201-516: Paul Ehrlich ( German: [ˈpaʊl ˈʔeːɐ̯lɪç] ; 14 March 1854 – 20 August 1915) was a Nobel Prize -winning German physician and scientist who worked in the fields of hematology , immunology and antimicrobial chemotherapy . Among his foremost achievements were finding a cure for syphilis in 1909 and inventing the precursor technique to Gram staining bacteria. The methods he developed for staining tissue made it possible to distinguish between different types of blood cells, which led to
402-707: A cerebral haemorrhage . He was 63 years old. Nobel wrote several wills during his lifetime. He composed the last over a year before he died, signing it at the Swedish–Norwegian Club in Paris on 27 November 1895. To widespread astonishment, Nobel's last will specified that his fortune be used to create a series of prizes for those who confer the "greatest benefit on mankind" in physics , chemistry , physiology or medicine , literature , and peace . Nobel bequeathed 94% of his total assets, 31 million SEK (c. US$ 186 million, €150 million in 2008), to establish
603-430: A habilitation thesis. In it he introduced the new technology of in vivo staining. One of his findings was that pigments can only be easily assimilated by living organisms if they are in granular form. He injected the dyes alizarin blue and indophenol blue into laboratory animals and established after their death that various organs had been coloured to different degrees. In organs with high oxygen saturation, indophenol
804-495: A theory of contagion in 1840, asked him to participate in his research project on uterine nerve structure. This research won him a research prize from the university and enabled him to briefly study under Rudolf Virchow , who was at the time considered "Germany's most renowned physician". In his sixth semester, Koch began to research at the Physiological Institute, where he studied the secretion of succinic acid , which
1005-459: A French newspaper. It was Alfred's brother Ludvig who had died; the obituary was eight years premature. The article disconcerted Nobel and made him apprehensive about how he would be remembered. This inspired him to change his will . Historians have been unable to verify this story and some dismiss the story as a myth. On 10 December 1896, Alfred Nobel died in his villa in San Remo, Italy , from
1206-612: A Victorian poet. The first Physiology or Medicine Prize went to the German physiologist and microbiologist Emil von Behring . During the 1890s, von Behring developed an antitoxin to treat diphtheria , which until then had been causing thousands of deaths each year. The first Nobel Peace Prize went to the Swiss Jean Henri Dunant for his role in founding the International Red Cross Movement and initiating
1407-415: A bacterium. He discovered the formation of spores in anthrax bacteria, which could remain dormant under specific conditions. However, under optimal conditions, the spores were activated and caused disease. To determine this causative agent, he dry-fixed bacterial cultures onto glass slides, used dyes to stain the cultures, and observed them through a microscope. His work with anthrax is notable in that he
1608-410: A barrier, with Lina Stern later coining the phrase. The medication triggered the so-called "Salvarsan war". On one side there was hostility on the part of those who feared a resulting moral breakdown of sexual inhibitions. Ehrlich was also accused, with clearly anti-Semitic undertones, of excessively enriching himself. In addition, Ehrlich's associate, Paul Uhlenhuth claimed priority in discovering
1809-558: A case of tuberculosis which he had contracted in the laboratory. Upon his return he established a private medical practice and small laboratory in Berlin-Steglitz. In 1891, Robert Koch invited Ehrlich to join the staff at his Berlin Institute of Infectious Diseases, where in 1896 a new branch, the Institute for Serum Research and Testing ( Institut für Serumforschung und Serumprüfung ), was established for Ehrlich's specialisation. Ehrlich
2010-402: A consequence of his patent claims, Nobel was eventually involved in a patent infringement lawsuit over cordite. Nobel amassed a fortune during his lifetime, with most of his wealth coming from his 355 inventions, of which dynamite is the most famous. There is a popular story about how, in 1888, Nobel was astonished to read his own obituary , titled "The Merchant of Death Is Dead", in
2211-488: A cytotoxic biologically active drug), as they enable cytotoxic drugs to be selectively delivered to their designated targets (e.g. cancer cells). In 1910, a street was named after Ehrlich in Frankfurt-Sachsenhausen. In Nazi Germany , Ehrlich's achievements were ignored while Emil Adolf von Behring was stylised as the ideal Aryan scientist, and the street named after Ehrlich was given another name. Shortly after

Hence, a " magic bullet " ( Zauberkugel , his term for an ideal therapeutic agent) would be created that killed only the organism targeted. The concept of a "magic bullet" has to some extent been realised by the development of antibody-drug conjugates (a monoclonal antibody linked to
2613-456: A district physician in Wollstein (today's Wolsztyn), Poland, in 1872, Robert began to delve into the disease called Anthrax. Near Wollstein, anthrax disease was regularly taking the lives of humans and livestock without evidence explaining why. Eventually, in 1876, Koch was able to make an incredible discovery that anthrax was triggered by one singular pathogen. Koch's discovery of the dormant stage,
2814-498: A doctorate with a dissertation entitled "Contributions to the Theory and Practice of Histological Staining" ( Beiträge zur Theorie und Praxis der histologischen Färbung ). One of the most outstanding results of his dissertation investigations was the discovery of a new cell type. Ehrlich discovered in the protoplasm of supposed plasma cells a granulate which could be made visible with the help of an alkaline dye. He thought this granulate
3015-435: A dye in his research on the tuberculosis pathogen. In Ehrlich's view, an added benefit was that methylene blue also stained the long appendages of nerve cells, the axons . He initiated a doctoral dissertation on the subject, but did not follow up the topic himself. It was the opinion of the neurologist Ludwig Edinger that Ehrlich had thereby opened up a major new topic in the field of neurology . After mid-1889, when Ehrlich
3216-518: A foundation established by Alfred Nobel would reward those who serve humanity. The Nobel Prize was funded by Alfred Nobel's personal fortune. According to the official sources, Alfred Nobel bequeathed most of his fortune to the Nobel Foundation that now forms the economic base of the Nobel Prize. The Nobel Foundation was founded as a private organisation on 29 June 1900. Its function is to manage
3417-443: A laboratory connected to his patient's examination room. His early research in this laboratory yielded one of his major contributions to the field of microbiology, as he developed the technique of growing bacteria. Furthermore, he managed to isolate and grow selected pathogens in a pure laboratory culture . His discovery of the anthrax bacillus (later named Bacillus anthracis ) hugely impressed Ferdinand Julius Cohn , professor at
3618-671: A lid to prevent contamination. The glass plate and the transparent culture media made observation of the bacterial growth easy. Koch publicly demonstrated his plating method at the Seventh International Medical Congress in London in August 1881. There, Louis Pasteur exclaimed, "C'est un grand progrès, Monsieur !" ("What a great progress, Sir!") It was using Koch's microscopy and agar-plate culture method that his students discovered new bacteria. Friedrich Loeffler discovered
3819-431: A liquid agar onto the glass slide and then spreading a thin layer of gelatin over it. The gelatin made the culture medium solidify, in which bacterial samples could be spread uniformly. The whole bacterial culture was then put on a glass plate together with a small wet paper. Koch named this container as feuchte Kammer (moist chamber). The typical chamber was a circular glass dish 20 cm in diameter and 5 cm in height and had
4020-428: A method for examining antibacterial activity by mixing the gelatin-based culture media with a yellow dye, auramin . His notebook indicates that by February 1890, he tested hundreds of compounds. In one of such tests, he found that an extract from the tuberculosis bacterium culture dissolved in glycerine could cure tuberculosis in guinea pigs. Based on a series of experiments from April to July 1891, he could conclude that
4221-596: A method for standardising therapeutic serums . In 1908, he received the Nobel Prize in Physiology or Medicine for his contributions to immunology. He was the founder and first director of what is now known as the Paul Ehrlich Institute , a German research institution and medical regulatory body that is the nation's federal institute for vaccines and biomedicines. A genus of Rickettsiales bacteria, Ehrlichia ,
SECTION 20
#17328555681914422-431: A new urine test which could be used to distinguish various types of typhoid from simple cases of diarrhea. The intensity of staining made possible a disease prognosis. The pigment solution he used is known today as Ehrlich's reagent. Ehrlich's great achievement, but also a source of problems during his further career, was that he had initiated a new field of study interrelating chemistry, biology and medicine. Much of his work
4623-539: A poorly equipped laboratory in Wollstein. He published the discovery in a booklet as " Die Ätiologie der Milzbrand-Krankheit, Begründet auf die Entwicklungsgeschichte des Bacillus Anthracis " ( The Etiology of Anthrax Disease, Based on the Developmental History of Bacillus Anthracis ) in 1876 while working at in Wöllstein. His publication in 1877 on the structure of anthrax bacterium marked the first photography of
4824-660: A private research foundation affiliated with his institute. Here he discovered in 1909 the first drug to be targeted against a specific pathogen: Salvarsan , a treatment for syphilis, which was at that time one of the most lethal and infectious diseases in Europe. In 1914, Ehrlich was awarded the Cameron Prize of the University of Edinburgh. Among the foreign guest scientists working with Ehrlich at his institute were two Nobel Prize winners, Henry Hallett Dale and Paul Karrer . The institute

Except for the Peace Prize, the Nobel Prizes are presented in Stockholm, Sweden, at the annual Prize Award Ceremony on 10 December, the anniversary of Nobel's death. The recipients' lectures are normally held in the days prior to the award ceremony. The Peace Prize and its recipients' lectures are presented at the annual Prize Award Ceremony in Oslo, Norway, usually on 10 December. The award ceremonies and
5226-432: A reference for testing other serums. For the test itself, toxin and serum were mixed in a ratio so that their effects just cancelled each other when injected into a guinea pig. But since there was a large margin in determining whether symptoms of illness were present, Ehrlich established an unambiguous target: the death of the animal. The mixture was to be such that the test animal would die after four days. If it died earlier,
5427-544: A small park known as Robert Koch Platz, just north of the Charity Hospital , in the Mitte section of Berlin . His life was the subject of a 1939 German-produced motion picture that featured Oscar-winning actor Emil Jannings in the title role. On 10 December 2017, Google showed a Doodle in celebration of Koch's birthday. Koch and his relationship to Paul Ehrlich , who developed a mechanism to diagnose TB, were portrayed in
5628-546: A solid funding base for the prizes and the administrative activities. The Nobel Foundation is exempt from all taxes in Sweden (since 1946) and from investment taxes in the United States (since 1953). Since the 1980s, the foundation's investments have become more profitable and as of 31 December 2007, the assets controlled by the Nobel Foundation amounted to 3.628 billion Swedish kronor (c. US$ 560 million). According to
5829-462: A stable concentration of diphtheria toxin was required. Ehrlich discovered that the toxin being used was perishable, in contrast to what had been assumed, which for him led to two consequences: he did not use the toxin as a standard, but instead a serum powder developed by Behring, which had to be dissolved in liquid shortly before use. The strength of a test toxin was first determined in comparison with this standard. The test toxin could then be used as

A prize may not be shared among more than three individuals, although the Nobel Peace Prize can be awarded to organisations of more than three people. Nobel Prizes are not awarded posthumously , but if a person is awarded a prize and dies before receiving it, the prize is presented. The Nobel Prizes, beginning in 1901, and the Nobel Memorial Prize in Economic Sciences, beginning in 1969, have been awarded 609 times to 975 people and 25 organisations. Five individuals and two organisations have received more than one Nobel Prize. Alfred Nobel

When Koch discovered tuberculin in 1890 as a medication for tuberculosis, he kept the experiment secret and avoided disclosing the source. It was only after a year under public pressure that he publicly announced the experiment and the source. Clinical trials with tuberculin were disastrous and complete failures. Rudolf Virchow's autopsy report of 21 subjects treated with tuberculin to

As such he is popularly nicknamed the father of microbiology (with Louis Pasteur ), and as the father of medical bacteriology. His discovery of the anthrax bacterium ( Bacillus anthracis ) in 1876 is considered as the birth of modern bacteriology. Koch used his discoveries to establish that germs "could cause a specific disease" and directly provided proofs for

Nomination forms are sent by the Nobel Committee to about 3,000 individuals, usually in September the year before the prizes are awarded. These individuals are generally prominent academics working in a relevant area. Regarding the Peace Prize, inquiries are also sent to governments, former Peace Prize laureates, and current or former members of

He was discharged a year later and was appointed as a district physician ( Kreisphysikus ) in Wollstein in Prussian Posen (now Wolsztyn , Poland). As his family settled there, his wife gave him a microscope as a birthday gift. With the microscope, he set up a private laboratory and started his career in microbiology. Koch began conducting research on microorganisms in

The award of the 2004 Literature Prize to Elfriede Jelinek drew a protest from a member of the Swedish Academy, Knut Ahnlund . Ahnlund resigned, alleging that the selection of Jelinek had caused "irreparable damage to all progressive forces, it has also confused the general view of literature as an art". He alleged that Jelinek's works were "a mass of text shovelled together without artistic structure". The 2009 Literature Prize to Herta Müller also generated criticism. According to The Washington Post , many US literary critics and professors were ignorant of her work. This made those critics feel

Koch reported his discovery to the German Secretary of State for the Interior on 2 February, and published it in the Deutsche Medizinische Wochenschrift ( German Medical Weekly ) the following month. Although Koch was convinced that the bacterium was the cholera pathogen, he could not entirely establish critical evidence the bacterium produced the symptoms in healthy subjects (following Koch's postulates ). His experiment on animals using his pure bacteria culture did not cause

It was already known that in some cases after a smallpox or syphilis infection, specific immunity was transmitted from the parents to their offspring. Ehrlich rejected inheritance in the genetic sense because the offspring of a male mouse immunised against abrin and an untreated female mouse were not immune to abrin. He concluded that the foetus was supplied with antibodies via

At their first meeting at the Seventh International Medical Congress in London in August 1881, Koch and Pasteur were friendly towards each other. But the rest of their careers followed with scientific disputes. The conflict started when Koch interpreted his discovery of anthrax bacillus in 1876 as causality, that is, the germ caused the anthrax infections. Although his postulates were not yet formulated, he did not establish

The International Committee of the Red Cross received it three times: in 1917 and 1944 for its work during the world wars; and in 1963 during the year of its centenary. The United Nations High Commissioner for Refugees has been awarded the Peace Prize twice for assisting refugees: in 1954 and 1981. The Curie family has received
11859-511: The Berlin Medical Society on 7 January 1891 revealed that instead of healing tuberculosis, the subjects died because of the treatment. One week later, Koch publicised that the drug was a glycerine extract of a pure cultivation of the tuberculosis bacilli. The German official report in late 1891 declared that tuberculosis was not cured with tuberculin. From this moment onwards, Koch's prestige fell apart. The reason for his initial secrecy

As director of the Georg-Speyer House, Ehrlich transferred his chemotherapeutic research there. He was looking for an agent which was as effective as methylene blue, but without its side effects. His model was on the one hand the impact of quinine on malaria, and on the other hand, in analogy to serum therapy, he thought there must also be chemical pharmaceuticals which would have just as specific an effect on individual diseases. His goal
12663-502: The Imperial Health Office was carrying out a project for disinfection of sputum of tuberculosis patients. Koch experimented with arsenic and creosote as possible disinfectants. These chemicals and other available drugs did not work. His report in 1883 also mentioned a failed experiment in an attempt to make a tuberculosis vaccine. By 1888, Koch turned his attention to synthetic dyes as antibacterial chemicals. He developed

Koch was made a Knight Grand Cross in the Prussian Order of the Red Eagle on 19 November 1890, and was elected a Foreign Member of the Royal Society (ForMemRS) in 1897. In 1905, he was awarded the Nobel Prize in Physiology and Medicine "for his investigations and discoveries in relation to tuberculosis." In 1906, research on tuberculosis and tropical diseases won him

Those hostile to the North and what they considered its deceptive practices during negotiations were deprived of a chance to criticise Lê Đức Thọ, as he declined the award. The satirist and musician Tom Lehrer has remarked that "political satire became obsolete when Henry Kissinger was awarded
14472-507: The Norwegian Nobel Committee fled into exile. The remaining members escaped persecution from the Germans when the Nobel Foundation stated that the committee building in Oslo was Swedish property. Thus it was a safe haven from the German military, which was not at war with Sweden. These members kept the work of the committee going, but did not award any prizes. In 1944, the Nobel Foundation, together with

All nomination records for a prize are sealed for 50 years from the awarding of
14874-543: The Physiology or Medicine Prize for his development of the prefrontal leucotomy . The previous year, Walter Freeman had developed a version of the procedure which was faster and easier to carry out. Due in part to the publicity surrounding the original procedure, Freeman's procedure was prescribed without due consideration or regard for modern medical ethics . Endorsed by such influential publications as The New England Journal of Medicine , leucotomy or "lobotomy" became so popular that about 5,000 lobotomies were performed in

Ehrlich's name is also borne by many schools and pharmacies, by the Paul-Ehrlich-Gesellschaft für Chemotherapie e. V. (PEG) in Frankfurt am Main, and the Paul-Ehrlich-Klinik in Bad Homburg vor der Höhe. The Paul Ehrlich and Ludwig Darmstaedter Prize
15477-489: The United States in the three years immediately following Moniz's receipt of the Prize. Robert Koch Heinrich Hermann Robert Koch ( / k ɒ x / KOKH ; German: [ˈʁoːbɛʁt ˈkɔx] ; 11 December 1843 – 27 May 1910) was a German physician and microbiologist . As the discoverer of the specific causative agents of deadly infectious diseases including tuberculosis , cholera and anthrax , he
15678-514: The University of Breslau (now the University of Wrocław ), who helped him publish the discovery in 1876. Cohn had established the Institute of Plant Physiology and invited Koch to demonstrate his new bacterium there in 1877. Koch was transferred to Breslau as district physician in 1879. A year after, he left for Berlin when he was appointed a government advisor at the Imperial Health Office, where he worked from 1880 to 1885. Following his discovery of
15879-414: The ability to diagnose numerous blood diseases . His laboratory discovered arsphenamine (Salvarsan), the first antibiotic and first effective medicinal treatment for syphilis , thereby initiating and also naming the concept of chemotherapy . Ehrlich introduced the concept of a magic bullet . He also made a decisive contribution to the development of an antiserum to combat diphtheria and conceived
16080-409: The age of 19, in 1862, Koch entered the University of Göttingen to study natural science. He took up mathematics, physics and botany. He was appointed assistant in the university's Pathological Museum. After three semesters, he decided to change his area of study to medicine, as he aspired to be a physician. During his fifth semester at the medical school, Jacob Henle , an anatomist who had published
16281-483: The anatomist Heinrich Wilhelm Waldeyer , Ehrlich continued the research started by his cousin in pigments and staining tissues for microscopic study. He spent his eighth university semester in Freiburg im Breisgau investigating primarily the red dye dahlia (monophenylrosanilin), giving rise to his first publication. In 1878 he followed his dissertation supervisor Julius Friedrich Cohnheim to Leipzig, and that year obtained
16482-480: The anthrax spores, allowed him to successfully unravel the mystery behind the anthrax disease. By gaining a better understanding of this pathogen, he was able to shed light on the bacterium's remarkable resistance to environmental factors (“Robert Koch – Nobel Lecture” 2018). This groundbreaking achievement marked Koch as the pioneer scientist to discover that a microscopic organism was causing a disease to spread. His findings were especially impressive as they were done in
16683-425: The antigen and the antibody he assumed there was an additional immune molecule, which he called an "additive" or a "complement". For him, the side chain contained at least two functional groups. For providing a theoretical basis for immunology as well as for his work on serum valency, Ehrlich was awarded the Nobel Prize for Physiology or Medicine in 1908 together with Élie Metchnikoff . Metchnikoff, who had researched
16884-567: The associated banquets are typically major international events. The Prizes awarded in Sweden's ceremonies are held at the Stockholm Concert Hall , with the Nobel banquet following immediately at Stockholm City Hall . The Nobel Peace Prize ceremony has been held at the Norwegian Nobel Institute (1905–1946), at the auditorium of the University of Oslo (1947–1989), and at Oslo City Hall (1990–present). The highlight of
17085-782: The award ceremony in Sweden, a banquet is held in the Blue Hall at the Stockholm City Hall , which is attended by the Swedish Royal Family and around 1,300 guests. The Nobel Peace Prize banquet is held in Norway at the Oslo Grand Hotel after the award ceremony. Apart from the laureate, guests include the president of the Storting , on occasion the Swedish prime minister, and, since 2006,
17286-483: The award, and others saying he had not secured the achievements to yet merit such an accolade. Obama's award, along with the previous Peace Prizes for Jimmy Carter and Al Gore , also prompted accusations of a liberal bias. Aung San Suu Kyi was awarded Peace Prize in 1993 however in 2015 when she came into power in Myanmar , she was criticized for being silent on human rights violation under her rule and especially over
17487-429: The bacilli present in the tuberculous lesions do not only accompany tuberculosis, but rather cause it. These bacilli are the true agents of tuberculosis. In August 1883, the German government sent a medical team led by Koch to Alexandria, Egypt , to investigate a cholera epidemic there. Koch soon found that the intestinal mucosa of people who died of cholera always had bacterial infection, yet could not confirm whether
17688-402: The bacteria of glanders ( Burkholderia mallei ) in 1882 and diphtheria ( Corynebacterium diphtheriae ) in 1884; and Georg Theodor August Gaffky , the bacterium of typhoid ( Salmonella enterica ) in 1884. Koch's assistant Julius Richard Petri developed an improved method and published it in 1887 as " Eine kleine Modification des Koch’schen Plattenverfahrens " (A minor modification of
17889-468: The bacteria were the causative pathogens. As the outbreak in Egypt declined, he was transferred to Calcutta (now Kolkata ) India, where there was a more severe outbreak. He soon found that the river Ganges was the source of cholera. He performed autopsies of almost 100 bodies, and found in each bacterial infection. He identified the same bacteria from water tanks, linking the source of the infection. He isolated
18090-420: The bacterium as the causative agent of cholera. Koch's colleague Richard Friedrich Johannes Pfeiffer correctly identified the comma bacillus as Pacini's vibrioni and renamed it as Vibrio cholera in 1896. Koch gave much of his research attention to tuberculosis throughout his career. After medical expeditions to various parts of the world, he again focussed on tuberculosis from the mid-1880s. By that time
18291-400: The bacterium as the cause of the disease: it was an inference. Pasteur therefore argued that Koch's discovery was not the full proof of causality, but Pasteur's anthrax vaccine developed in 1881 was. Koch published his conclusion in 1881 with a statement: "anthrax never occurs without viable anthrax bacilli or spores. In my opinion no more conclusive proof can be given that anthrax bacilli are
18492-420: The bacterium in pure culture on 7 January 1884. He subsequently confirmed that the bacterium was a new species, and described as "a little bent, like a comma." His experiment using fresh blood samples indicated that the bacterium could kill red blood cells, and he hypothesized that some sort of poison was used by the bacterium to cause the disease. In 1959, Indian scientist Sambhu Nath De discovered this poison,
18693-432: The causative agent of anthrax led to the formation of a generic set of postulates which can be used in the determination of the cause of most infectious diseases. These postulates, which not only outlined a method for linking cause and effect of an infectious disease but also established the significance of laboratory culture of infectious agents, became the "gold standard" in infectious diseases. Although Koch worked out
18894-521: The causative agent of the disease to be the slow-growing Mycobacterium tuberculosis . He published the discovery as " Die Ätiologie der Tuberkulose " ( The Etiology of Tuberculosis ), and presented before the German Physiological Society at Berlin on 24 March 1882. Koch said, When the cover-glasses were exposed to this staining fluid [methylene blue mixed with potassium hydroxide ] for 24 hours, very fine rod-like forms became apparent in
19095-556: The cellular branch of immunity, Phagocytosis , at the Pasteur Institute had previously sharply attacked Ehrlich. In 1901, the Prussian Ministry of Finance criticised Ehrlich for exceeding his budget and as a consequence reduced his income. In this situation Althoff arranged a contact with Georg Speyer, a Jewish philanthropist and joint owner of the bank house Lazard Speyer-Ellissen. The cancerous disease of Princess Victoria ,
19296-459: The conventional therapy of mercury salts. Manufactured by Hoechst AG, Salvarsan became the most widely prescribed drug in the world. It was the most effective drug for treating syphilis until penicillin became available in the 1940s. Salvarsan required improvement as to side effects and solubility and was replaced in 1911 with Neosalvarsan . Ehrlich's work illuminated the existence of the blood-brain barrier , although he himself never believed in such
19497-520: The country, however, the more they too seemed to develop a resistance against it. During his time as government advisor, Koch published a report on how he discovered and experimentally showed tuberculosis bacterium as the pathogen of tuberculosis. He described the importance of pure cultures in isolating disease-causing organisms and explained the necessary steps to obtain these cultures, methods which are summarized in Koch's four postulates . Koch's discovery of
19698-675: The death of this meritorious researcher for his great service to medical science and suffering humanity; his life’s work ensures undying fame and the gratitude of both his contemporaries and posterity". Ehrlich was buried at the Old Jewish Cemetery, Frankfurt (Block 114 N). In the early 1870s, Ehrlich's cousin Karl Weigert was the first person to stain bacteria with dyes and to introduce aniline pigments for histological studies and bacterial diagnostics. During his studies in Strassburg under
19899-409: The decision to award Steinman the prize "was made in good faith", it would remain unchanged, and the prize would be awarded. Nobel's will provided for prizes to be awarded in recognition of discoveries made "during the preceding year". Early on, the awards usually recognised recent discoveries. However, some of those early discoveries were later discredited. For example, Johannes Fibiger was awarded
20100-467: The decisive factor that enabled the Nobel Prizes to be established". Another important task of the Nobel Foundation is to market the prizes internationally and to oversee informal administration related to the prizes. The foundation is not involved in the process of selecting the Nobel laureates . In many ways, the Nobel Foundation is similar to an investment company , in that it invests Nobel's money to create
20301-474: The diploma and medal. Even though Sweden was officially neutral during the Second World War, the prizes were awarded irregularly. In 1939, the Peace Prize was not awarded. No prize was awarded in any category from 1940 to 1942, due to the occupation of Norway by Germany . In the subsequent year, all prizes were awarded except those for literature and peace. During the occupation of Norway, three members of
20502-710: The discovery of the tuberculosis bacterium, 24 March 1882, has been observed by the World Health Organization as " World Tuberculosis Day " every year since 1982. Koch was born in Clausthal, Germany , on 11 December 1843, to Hermann Koch (1814–1877) and Mathilde Julie Henriette (née Biewend; 1818–1871). His father was a mining engineer. He was the third of thirteen siblings. He excelled academically from an early age. Before entering school in 1848, he had taught himself how to read and write. He completed secondary education in 1862, having excelled in science and math. At
20703-465: The disease, and correctly explained that animals are immune to human pathogen. The bacterium was then known as "the comma bacillus", and scientifically as Bacillus comma . It was later realised that the bacterium was already described by an Italian physician Filippo Pacini in 1854, and was also observed by the Catalan physician Joaquim Balcells i Pascual around the same time. But they failed to identify
20904-432: The drug. Because some people died during the clinical testing, Ehrlich was accused of "stopping at nothing." In 1914, one of the most prominent accusers was convicted of criminal libel at a trial for which Ehrlich was called to testify. Though Ehrlich was thereby exonerated, the ordeal threw him into a depression from which he never fully recovered. Ehrlich reasoned that if a compound could be made that selectively targeted
21105-409: The end of the war the name Paul-Ehrlich-Strasse was reinstated, and today numerous German cities have streets named after Ehrlich. West Germany issued a postage stamp in 1954 on the 100th anniversary of the births of Ehrlich (14 March 1854) and Emil von Behring (15 March 1854). The 200 Deutsche Mark bank note, issued until 2001, featured Ehrlich. The German Paul Ehrlich Institute, the successor to
21306-502: The existence of nucleated red blood cells, which he subdivided into normoblasts, megaloblasts, microblasts and poikiloblasts; he had discovered the precursors of erythrocytes. Ehrlich thus also laid the basis for the analysis of anemias , after he had created the basis for systematising leukemias with his investigation of white blood cells. His duties at the Charité included analysing patients' blood and urine specimens. In 1881 he published
21507-498: The extent that Ehrlich was quickly able to increase the level of immunity of the laboratory animals based on his experience with mice. Clinical tests with diphtheria serum early in 1894 were successful and in August the chemical company Hoechst started to market Behring's "Diphtheria Remedy synthesised by Behring-Ehrlich". The two discoverers had originally agreed to share any profits after the Hoechst share had been subtracted. Their contract
21708-555: The extract did not kill the tuberculosis bacterium, but destroyed (by necrosis ) the infected tissues, thereby depriving bacterial growth. He made a vague announcement in August 1890 at the Tenth International Medical Congress in Berlin, saying, In a communication which I made a few months ago to the International Medical Congress [in London in 1881], I described a substance of which the result
21909-472: The finances and administration of the Nobel Prizes. In accordance with Nobel's will , the primary task of the foundation is to manage the fortune Nobel left. Robert and Ludvig Nobel were involved in the oil business in Azerbaijan , and according to Swedish historian E. Bargengren, who accessed the Nobel family archive , it was this "decision to allow withdrawal of Alfred's money from Baku that became
22110-594: The first microtomes ), he became fascinated by the process of staining microscopic tissue substances. He retained that interest during his subsequent medical studies at the universities of Breslau, Strasbourg , Freiburg im Breisgau and Leipzig . After obtaining his doctorate in 1882, he worked at the Charité in Berlin as an assistant medical director under Theodor Frerichs, the founder of experimental clinical medicine, focusing on histology , hematology and colour chemistry (dyes). He married Hedwig Pinkus (1864–1948) in 1883 in
22311-545: The five Nobel Prizes. Owing to skepticism surrounding the will, it was not approved by the Storting in Norway until 26 April 1897. The executors of the will, Ragnar Sohlman and Rudolf Lilljequist, formed the Nobel Foundation to take care of the fortune and to organise the awarding of prizes. Nobel's instructions named a Norwegian Nobel Committee to award the Peace Prize , the members of which were appointed shortly after
22512-470: The grant equally, or awarding one-half to one recipient and one-quarter to each of the others. It is common for recipients to donate prize money to benefit scientific, cultural, or humanitarian causes. Five people have received two Nobel Prizes. Marie Curie received the Physics Prize in 1903 for her work on radioactivity and the Chemistry Prize in 1911 for the isolation of pure radium , making her
22713-426: The holders. After the war, the gold was recovered from solution, and the medals re-cast. Nobel laureates receive a diploma directly from the hands of the King of Sweden, or in the case of the peace prize, the chairman of the Norwegian Nobel Committee. Each diploma is uniquely designed by the prize-awarding institutions for the laureates that receive them. The diploma contains a picture and text in Swedish which states
22914-568: The human bacillus. " Chair of the congress, Joseph Lister reprimanded Koch and explained the medical evidence of cattle tuberculosis in humans. The Nobel Committee selected the 1902 Nobel Prize in Physiology or Medicine to be awarded for the discovery of the transmission of malaria. But it could not make the final decision on whom to give it to — the British surgeon Ronald Ross or the Italian biologist Giovanni Battista Grassi . Ross had discovered that
23115-412: The human malarial parasite was carried by certain mosquitoes in 1897, and the next year that bird malaria could be transmitted from infected to healthy birds by the bite of a mosquito. Grassi had discovered Plasmodium vivax and the bird malaria parasite, and towards the end of 1898 the transmission of Plasmodium falciparum between humans through mosquitoes Anopheles claviger . To the surprise of
23316-472: The immunity reaction, so easily produced by all kinds of cells, is prevented from acting against the organism's own elements". Emil Behring had worked at the Berlin Institute of Infectious Diseases until 1893 on developing an antiserum for treating diphtheria and tetanus but with inconsistent results. Koch suggested that Behring and Ehrlich cooperate on the project. This joint work was successful to
23517-451: The institute, as was tuberculin and later on various vaccines . Ehrlich's most important colleague at the institute was the Jewish physician and biologist Julius Morgenroth. Ehrlich postulated that cell protoplasm contains special structures which have chemical side chains (today's term is macromolecules ) to which the toxin binds, affecting function. If the organism survives the effects of
23718-506: The invention of the transistor and in 1972 for the theory of superconductivity . Frederick Sanger received the prize twice in Chemistry: in 1958 for determining the structure of the insulin molecule and in 1980 for inventing a method of determining base sequences in DNA. Karl Barry Sharpless was awarded the 2001 Chemistry Prize for his research into chirally catalysed oxidation reactions, and
23919-434: The laureates arriving in Stockholm and normally ends with the Nobel banquet), but this is not mandatory. The laureate is only obliged to give the lecture within six months of receiving the prize, but some have happened even later. For example, US President Theodore Roosevelt received the Peace Prize in 1906 but gave his lecture in 1910, after his term in office. The lectures are organised by the same association which selected
24120-541: The laureates. Military cemeteries in every corner of the world are silent testimony to the failure of national leaders to sanctify human life. The Nobel Foundation announced on 30 May 2012 that it had awarded the contract for the production of the five (Swedish) Nobel Prize medals to Svenska Medalj AB. Between 1902 and 2010, the Nobel Prize medals were minted by Myntverket (the Swedish Mint), Sweden's oldest company, which ceased operations in 2011 after 107 years. In 2011,
24321-506: The lecture in which he reported how he was able to identify the tuberculosis pathogen . Ehrlich later described this lecture as his "greatest experience in science". The day after Koch's lecture, Ehrlich had already made an improvement to Koch's staining method, which Koch unreservedly welcomed. From this date on, the two men were bound in friendship. In 1887 Ehrlich became an unsalaried lecturer in internal medicine ( Privatdozent für Innere Medizin ) at Berlin University, and in 1890 took over
24522-566: The life cycle of the anthrax pathogen and had contacted Ferdinand Cohn , who was quickly convinced by Koch's work and introduced him to his Breslau colleagues. From 30 April to 2 May 1876, Koch presented his investigations in Breslau, which the student Ehrlich was able to attend. On 24 March 1882, Ehrlich was present when Koch, working since 1880 at the Imperial Public Health Office ( Kaiserliches Gesundheitsamt ) in Berlin, presented
24723-405: The malaria plasmodia disappeared from their blood. Ehrlich obtained methylene blue from the company Meister Lucius & Brüning AG (later renamed Hoechst AG), which started a long collaboration with this company. Before the Institute of Experimental Therapy had moved to Frankfurt, Ehrlich had already resumed work on methylene blue. After the death of Georg Speyer, his widow Franziska Speyer endowed
24924-492: The months between their nomination and the decision of the prize committee were originally eligible to receive the prize. This has occurred twice: the 1931 Literature Prize awarded to Erik Axel Karlfeldt , and the 1961 Peace Prize awarded to UN Secretary General Dag Hammarskjöld . Since 1974, laureates must be thought alive at the time of the October announcement. There has been one laureate, William Vickrey , who in 1996 died after
25125-538: The most criticised Nobel Peace Prizes was the one awarded to Henry Kissinger and Lê Đức Thọ . This led to the resignation of two Norwegian Nobel Committee members. Kissinger and Thọ were awarded the prize for negotiating a ceasefire between North Vietnam and the United States in January 1973 during the Vietnam War . However, when the award was announced, both sides were still engaging in hostilities. Critics sympathetic to
25326-475: The most prizes, with four prizes awarded to five individual laureates. Marie Curie received the prizes in Physics (in 1903) and Chemistry (in 1911). Her husband, Pierre Curie , shared the 1903 Physics prize with her. Their daughter, Irène Joliot-Curie , received the Chemistry Prize in 1935 together with her husband Frédéric Joliot-Curie . In addition, the husband of Marie Curie's second daughter, Henry Labouisse ,
25527-498: The name "Koch dish" had been given. During his time as the government advisor with the Imperial Health Agency in Berlin in the 1880s, Koch became interested in tuberculosis research. At the time, it was widely believed that tuberculosis was an inherited disease. However, Koch was convinced that the disease was caused by a bacterium and was infectious. In 1882, he published his findings on tuberculosis, in which he reported
25728-694: The name literally means "nonpoisonous", atoxyl does cause damage, especially to the optic nerve. Ehrlich elaborated the systematic testing of chemical compounds in the sense of screening as now practiced in the pharmaceutical industry. He discovered that Compound 418 - Arsenophenylglycine - had an impressive therapeutic effect and had it tested in Africa. With the support of his assistant Sahachiro Hata Ehrlich discovered in 1909 that Compound 606, Arsphenamine , effectively combatted " spirillum " spirochaetes bacteria, one of whose subspecies causes syphilis . The compound proved to have few side effects in human trials, and
25929-422: The name of the laureate and normally a citation of why they received the prize. None of the Nobel Peace Prize laureates has ever had a citation on their diplomas. The laureates are given a sum of money when they receive their prizes, in the form of a document confirming the amount awarded. The amount of prize money depends upon how much money the Nobel Foundation can award each year. The purse has increased since
26130-664: The obverse of the Peace Prize medal and the medal for the Economics Prize, but with a slightly different design. For instance, the laureate's name is engraved on the rim of the Economics medal. The image on the reverse of a medal varies according to the institution awarding the prize. The reverse sides of the medals for chemistry and physics share the same design. All medals made before 1980 were struck in 23 carat gold. Since then, they have been struck in 18 carat green gold plated with 24 carat gold. The weight of each medal varies with
26331-432: The only person to be awarded a Nobel Prize in two different sciences. Linus Pauling was awarded the 1954 Chemistry Prize for his research into the chemical bond and its application to the structure of complex substances. Pauling was also awarded the Peace Prize in 1962 for his activism against nuclear weapons, making him the only laureate of two unshared prizes. John Bardeen received the Physics Prize twice: in 1956 for
26532-469: The other hand, Paul Ehrlich later recollected that this moment was his "single greatest scientific experience." Koch expanded the report and published it under the same title as a booklet in 1884, in which he concluded that the discovery of tuberculosis bacterium fulfilled the three principles, eventually known as Koch's postulates , which were formulated by his assistant Friedrich Loeffler in 1883, saying: All these factors together allow me to conclude that
26733-478: The pathological process can be brought to a complete standstill. By November 1890, Koch demonstrated the effectiveness of the extract in treating humans by administering the vaccine through the Bacillus Calmette-Guerin (BCG) technique. This absorbs the vaccine through the skin by means of multiple shallow punctures on the skin and many patients and doctors went to Berlin to get Koch's remedy. While this
26934-430: The plating technique of Koch). The culture plate was given an eponymous name Petri dish . It is often asserted that Petri developed a new culture plate, but this was not so. He simply discarded the use of glass plate and instead used the circular glass dish directly, not just as a moist chamber, but as the main culture container. This further reduced the chances of contaminations. It would also have been appropriate if
27135-486: The poet Sully Prudhomme for the first Nobel Prize in Literature. A group including 42 Swedish writers, artists, and literary critics protested against this decision, having expected Leo Tolstoy to be awarded. Some, including Burton Feldman , have criticised this prize because they consider Prudhomme a mediocre poet. Feldman's explanation is that most of the academy members preferred Victorian literature and thus selected
27336-424: The poisons ricin and abrin . After feeding them with small but increasing dosages of ricin he ascertained that they had become "ricin-proof". Ehrlich interpreted this as immunisation and observed that it was abruptly initiated after a few days and was still in existence after several months, but mice immunised against ricin were just as sensitive to abrin as untreated animals. This was followed by investigations on
27537-424: The possibility that an organism's immune system could attack the organism's own tissue calling it "horror autotoxicus". It was Ehrlich's student, Ernest Witebsky , who demonstrated that autoimmunity could cause disease in humans. Ehrlich was the first to propose that regulatory mechanisms existed to protect an organism from autoimmunity, saying in 1906 that "the organism possesses certain contrivances by means of which
27738-533: The preceding year, have conferred the greatest benefit to humankind, as established by the 1895 will of Swedish chemist, engineer, and industrialist Alfred Nobel , in the year before he died. Prizes were first awarded in 1901 by the Nobel Foundation . Nobel's will indicated that the awards should be granted in the fields of Physics , Chemistry , Physiology or Medicine , Literature , and Peace . A sixth prize for Economic Sciences , endowed by Sweden 's central bank, Sveriges Riksbank , and first presented in 1969,
27939-582: The primary tumor is removed, then metastasis precipitously increases. Ehrlich applied bacteriological methods to cancer research. In analogy to vaccination, he attempted to generate immunity to cancer by injecting weakened cancer cells. Both in cancer research and chemotherapy research (see below) he introduced the methodologies of Big Science . In 1885 Ehrlich's monograph "The Need of the Organism for Oxygen" ( Das Sauerstoffbedürfnis des Organismus – Eine farbenanalytische Studie ) appeared, which he also submitted as
28140-454: The principles, he did not formulate the postulates, which were introduced by his assistant Friedrich Loeffler. Loeffler, reporting his discovery of diphtheria bacillus in 1883, stated three postulates as follows: The fourth postulate was added by an American plant pathologist Erwin Frink Smith in 1905, and is stated as: In July 1867, Koch married Emma (Emmy) Adolfine Josephine Fraatz, and
28341-487: The prize (in Economics ) was announced but before it could be presented. On 3 October 2011, the laureates for the Nobel Prize in Physiology or Medicine were announced; however, the committee was not aware that one of the laureates, Ralph M. Steinman , had died three days earlier. The committee was debating about Steinman's prize, since the rule is that the prize is not awarded posthumously. The committee later decided that as
28542-420: The prize. The Nobel Committee then prepares a report reflecting the advice of experts in the relevant fields. This, along with the list of preliminary candidates, is submitted to the prize-awarding institutions. There are four awarding institutions for the six prizes awarded: The institutions meet to choose the laureate or laureates in each field by a majority vote. Their decision, which cannot be appealed,
28743-450: The prize. In the last decades of the 19th century, many chemists had made significant contributions. Thus, with the Chemistry Prize, the academy "was chiefly faced with merely deciding the order in which these scientists should be awarded the prize". The academy received 20 nominations, eleven of them for Jacobus van 't Hoff . Van 't Hoff was awarded the prize for his contributions in chemical thermodynamics . The Swedish Academy chose
28944-412: The prizes were too Eurocentric. The 2019 Literature Prize to Peter Handke received heavy criticisms from various authors, such as Salman Rushdie and Hari Kunzru , and was condemned by the governments of Bosnia and Herzegovina , Kosovo , and Turkey , due to his history of Bosnian genocide denialism and his support for Slobodan Milošević . In 1949, the neurologist António Egas Moniz received
29145-443: The pulmonary circulation of the mother. This idea was supported by the fact that this "inherited immunity" decreased after a few months. In another experiment he exchanged the offspring of treated and untreated female mice. The mice which were nursed by the treated females were protected from the poison, providing the proof that antibodies can also be conveyed in milk. Ehrlich also researched autoimmunity , but he specifically rejected
29346-492: The right to apply for patent protection. In 1906, he moved to East Africa to research a cure for trypanosomiasis (sleeping sickness). He established the Bugula research camp where up to 1000 people a day were treated with the experimental drug Atoxyl . Robert Koch made two important developments in microscopy; he was the first to use an oil immersion lens and a condenser that enabled smaller objects to be seen. In addition, he
29547-457: The serum was too weak and was rejected. Ehrlich claimed to have made the determination of the valency of serum as accurate as it would be with chemical titration . This again demonstrates his tendency to quantify the life sciences. Influenced by the mayor of Frankfurt am Main, Franz Adickes, who endeavored to establish science institutions in Frankfurt in preparation of the founding of a university, Ehrlich's institute moved to Frankfurt in 1899 and
29748-469: The site of the injection becomes dark, and eventually heals normally and quickly (Moreland, 2024). The uncertainty in the chemical nature coined the term phenomenon in the name “Koch’s phenomenon.” Koch published his experiments in the 15 January 1891 issue of Deutsche Medizinische Wochenschrift , and The British Medical Journal immediately published the English version simultaneously. The English version
29949-482: The spirochetes disappeared in seven syphilis patients after this treatment. After extensive clinical testing (all the research participants had the negative example of tuberculin in mind) the Hoechst company began to market the compound toward the end of 1910 under the name Salvarsan. This was the first agent with a specific therapeutic effect to be created on the basis of theoretical considerations. Salvarsan proved to be amazingly effective, particularly when compared with
30150-546: The statutes, the foundation consists of a board of five Swedish or Norwegian citizens, with its seat in Stockholm. The chairman of the board is appointed by the Swedish King in Council , with the other four members appointed by the trustees of the prize-awarding institutions . An Executive director is chosen from among the board members , a deputy director is appointed by the King in Council, and two deputies are appointed by
30351-682: The synagogue in Neustadt (now Prudnik, Poland). The couple had two daughters, Stephanie and Marianne. Hedwig was a sister of Max Pinkus , who was an owner of the textile factory in Neustadt (later known as ZPB "Frotex" ). He settled in the villa of the Fränkel family on Wiesenerstrasse in Neustadt. After completing his clinical education and habilitation at the prominent Charité medical school and teaching hospital in Berlin in 1886, Ehrlich travelled to Egypt and other countries in 1888 and 1889, in part to cure
30552-547: The three members in exile, made sure that nominations were submitted for the Peace Prize and that the prize could be awarded once again. In 1968, Sweden's central bank Sveriges Riksbank celebrated its 300th anniversary by donating a large sum of money to the Nobel Foundation to be used to set up a prize in honour of Alfred Nobel. The following year, the Sveriges Riksbank Prize in Economic Sciences in Memory of Alfred Nobel
30753-668: The title role. It focused on Salvarsan (arsphenamine, " compound 606 "), his cure for syphilis. Since the Nazi government was opposed to this tribute to a Jewish scientist, attempts were made to keep the film a secret in Germany. The film was nominated for an Academy Award for Best Original Screenplay . Nobel Prize The Nobel Prizes ( / n oʊ ˈ b ɛ l / noh- BEL ; Swedish : Nobelpriset [nʊˈbɛ̂lːˌpriːsɛt] ; Norwegian : Nobelprisen [nʊˈbɛ̀lːˌpriːsn̩] ) are five separate prizes awarded to those who, during
30954-414: The total annual cost was approximately 120 million kronor , with 50 million kronor as the prize money. Further costs to pay institutions and persons engaged in giving the prizes were 27.4 million kronor. The events during the Nobel week in Stockholm and Oslo cost 20.2 million kronor. The administration, Nobel symposium , and similar items had costs of 22.4 million kronor. The cost of
31155-441: The toxin, the blocked side-chains are replaced by new ones. This regeneration can be trained, the name for this phenomenon being immunisation . If the cell produces a surplus of side chains, these might also be released into the blood as antibodies. In the following years Ehrlich expanded his side chain theory using concepts ("amboceptors", "receptors of the first, second and third order", etc.) which are no longer customary. Between
31356-496: The treatment. An attempt to use tuberculin as a therapeutic drug is regarded as Koch's "greatest failure." With it his reputation greatly waned. But he devoted the rest of his life trying to make tuberculin as a usable medication. His discovery was not a total failure: the substance is now used to test for hypersensitivity in tuberculosis patients. Koch observed the phenomenon of acquired immunity . On 26 December 1900, he arrived as part of an expedition to German New Guinea , which
31557-639: The true and only cause of anthrax," and that vaccination such as claimed by Pasteur would be impossible. To prove his vaccine, Pasteur sent his assistant Louis Thuillier to Germany for demonstration and disproved Koch's idea. They had a heated public debate at the International Congress for Hygiene in Geneva in 1882, where Koch criticised Pasteur's methods as "unreliable," and claimed they "are false and [as such ] they inevitably lead to false conclusions." Koch later continued to attack Pasteur, saying, "Pasteur
31758-461: The trustees of these institutions, and auditors . The capital of the Nobel Foundation today is invested 50% in shares , 20% bonds and 30% other investments (e.g. hedge funds or real estate ). The distribution can vary by 10 percent. At the beginning of 2008, 64% of the funds were invested mainly in American and European stocks, 20% in bonds, plus 12% in real estate and hedge funds. In 2011,
31959-587: The tubercular mass for the first time, having, as further observations showed, the power of multiplication and of spore formation and hence belonging to the same group of organisms as the anthrax bacillus... Microscopic examination then showed that only the previously blue-stained cell nuclei and detritus became brown, while the tubercle bacilli remained a beautiful blue. There was no particular reaction to this announcement. Eminent scientists such as Rudolf Virchow remained sceptical. Virchow clung to his theory that all diseases are due to faulty cellular activities. On
32160-492: The tuberculosis bacterium, he was promoted to Geheimer Regierungsrat , a senior executive position, in June 1882. In 1885, Koch received two appointments as an administrator and professor at Berlin University . He became Director of Hygienic Institute and Chair (Professor of hygiene) of the Faculty of Medicine. In 1891, he relinquished his professorship and became a director of the Royal Prussian Institute for Infectious Diseases (now
32361-541: The tuberculosis station at a public hospital in Berlin-Moabit at Koch's request. This was where Koch's hoped-for tuberculosis therapeutic agent tuberculin was under study; and Ehrlich had even injected himself with it. In the ensuing tuberculin scandal , Ehrlich tried to support Koch and stressed the value of tuberculin for diagnostic purposes. In 1891 Koch invited Ehrlich to work at the newly founded Institute of Infectious Diseases ( Institut für Infektionskrankheiten – now
32562-539: The two had a daughter, Gertrude, in 1868. Their marriage ended after 26 years in 1893, and later that same year, he married actress Hedwig Freiberg (1872–1945). On 9 April 1910, Koch suffered a heart attack and never made a complete recovery. On 27 May, three days after giving a lecture on his tuberculosis research at the Prussian Academy of Sciences , Koch died in Baden-Baden at the age of 66. Following his death,
32763-714: The value of gold, but averages about 175 grams (0.386 lb) for each medal. The diameter is 66 millimetres (2.6 in) and the thickness varies between 5.2 millimetres (0.20 in) and 2.4 millimetres (0.094 in). Because of the high value of their gold content and tendency to be on public display, Nobel medals are subject to medal theft. During World War II, the medals of German scientists Max von Laue and James Franck were sent to Copenhagen for safekeeping. When Germany invaded Denmark, Hungarian chemist (and Nobel laureate himself) George de Hevesy dissolved them in aqua regia (nitro-hydrochloric acid), to prevent confiscation by Nazi Germany and to prevent legal problems for
32964-539: The widow of the German Emperor Friedrich II, had received much public attention and prompted a collection among wealthy Frankfurt citizens, including Speyer, in support of cancer research. Ehrlich had also received from the German Emperor Wilhelm II a personal request to devote all his energy to cancer research. Such efforts led to the founding of a department for cancer research affiliated with
33165-476: The wife of his first cousin, who won solo for Chemistry in 1964. Jan Tinbergen , who was awarded the first Economics Prize in 1969, was the brother of Nikolaas Tinbergen , who received the 1973 Physiology or Medicine Prize. Gunnar Myrdal , who was awarded the Economics Prize in 1974, was the husband of Alva Myrdal , Peace Prize laureate in 1982. Economics laureates Paul Samuelson (1970) and Kenneth Arrow (1972; shared) were brothers-in-law. Frits Zernike , who
33366-690: The will was approved in April 1897. Soon thereafter, the other prize-awarding organisations were designated. These were the Karolinska Institute on 7 June, the Swedish Academy on 9 June, and the Royal Swedish Academy of Sciences on 11 June. The Nobel Foundation reached an agreement on guidelines for how the prizes should be awarded; and, in 1900, the Nobel Foundation's newly created statutes were promulgated by King Oscar II . According to his will and testament read in Stockholm on 30 December 1896,
33567-412: The year when the full impact of the discovery has become evident." The interval between the award and the accomplishment it recognises varies from discipline to discipline. The Literature Prize is typically awarded to recognise a cumulative lifetime body of work rather than a single achievement. The Peace Prize can also be awarded for a lifetime body of work. For example, 2008 laureate Martti Ahtisaari
33768-633: Was a dry specimen technique, which he also developed. A drop of blood placed between two glass slides and heated over a Bunsen burner fixed the blood cells while still allowing them to be stained. Ehrlich used both alkaline and acid dyes, and also created new "neutral" dyes. For the first time this made it possible to differentiate the lymphocytes among the leucocytes (white blood cells). By studying their granulation he could distinguish between nongranular lymphocytes, mono- and poly-nuclear leucocytes, eosinophil granulocytes and mast cells. Starting in 1880, Ehrlich also studied red blood cells . He demonstrated
33969-470: Was a sign of good nourishment, and accordingly named these cells mast cells , (from the German word for an animal-fattening feed, Mast ). This focus on chemistry was unusual for a medical dissertation. In it, Ehrlich presented the entire spectrum of known staining techniques and the chemistry of the pigments employed. While he was at the Charité, Ehrlich elaborated upon the differentiation of white blood cells according to their different granules. A precondition
34170-588: Was also reproduced in Nature , and The Lancet in the same month. The Lancet presented it as "glad tidings of great joy." Koch simply referred to the medication as "brownish, transparent fluid." Josephs Pohl-Pincus had used the name tuberculin in 1844 for tuberculosis culture media, and Koch subsequently adopted as "tuberkulin." The first report on the clinical trial in 1891 was disappointing. By then 1061 patients with tuberculosis of internal organs and of 708 patients with tuberculosis of external tissues were given
34371-595: Was also the first to effectively use photography ( microphotography ) for microscopic observation. He introduced the "bedrock methods" of bacterial staining using methylene blue and Bismarck (Vesuvin) brown dye . In an attempt to grow bacteria, Koch began to use solid nutrients such as potato slices. Through these initial experiments, Koch observed individual colonies of identical, pure cells. He found that potato slices were not suitable media for all organisms, and later began to use nutrient solutions with gelatin . However, he soon realized that gelatin, like potato slices,
34572-604: Was awarded for his work to resolve international conflicts. However, they can also be awarded for specific recent events. For instance, Kofi Annan was awarded the 2001 Peace Prize just four years after becoming the Secretary-General of the United Nations. Similarly Yasser Arafat , Yitzhak Rabin , and Shimon Peres received the 1994 award, about a year after they successfully concluded the Oslo Accords . A controversy
34773-417: Was awarded for the first time. The Royal Swedish Academy of Sciences became responsible for selecting laureates. The first laureates for the Economics Prize were Jan Tinbergen and Ragnar Frisch "for having developed and applied dynamic models for the analysis of economic processes". The board of the Nobel Foundation decided that after this addition, it would allow no further new prizes. The award process
34974-501: Was awarded the 1953 Physics Prize, was the great-uncle of 1999 Physics laureate Gerard 't Hooft . In 2019, married couple Abhijit Banerjee and Esther Duflo were awarded the Economics Prize. Christiane Nüsslein-Volhard was awarded the Prize in Physiology or Medicine in 1995, and her nephew Benjamin List received the Chemistry Prize in 2021. Sune Bergström was awarded the Prize in Physiology or Medicine in 1982, and his son Svante Pääbo
35175-629: Was awarded the same prize in 2022. Edwin McMillan , who shared the Prize in Chemistry in 1951, was the uncle of John Clauser , who was awarded the Prize in Physics in 2022. Among other criticisms, the Nobel Committees have been accused of having a political agenda, and of omitting more deserving candidates. They have also been accused of Eurocentrism , especially for the Literature Prize. Among
35376-422: Was awarded to Manne Siegbahn in 1924, followed by his son, Kai Siegbahn , in 1981. Hans von Euler-Chelpin , who received the Chemistry Prize in 1929, was the father of Ulf von Euler , who was awarded the Physiology or Medicine Prize in 1970. C. V. Raman was awarded the Physics Prize in 1930 and was the uncle of Subrahmanyan Chandrasekhar , who was awarded the same prize in 1983. Arthur Kornberg received
35577-400: Was born on 21 October 1833 in Stockholm , Sweden, into a family of engineers. He was a chemist , engineer , and inventor . In 1894, Nobel purchased the Bofors iron and steel mill, which he made into a major armaments manufacturer . Nobel also invented ballistite . This invention was a precursor to many smokeless military explosives, especially the British smokeless powder cordite . As
35778-498: Was caused by awarding the 2009 Nobel Peace Prize to Barack Obama during his first year as US president. Awards for physics, chemistry, and medicine are typically awarded once the achievement has been widely accepted. Sometimes, this takes decades – for example, Subrahmanyan Chandrasekhar shared the 1983 Physics Prize for his 1930s work on stellar structure and evolution. Not all scientists live long enough for their work to be recognised. Some discoveries can never be considered for
35979-432: Was changed several times and finally Ehrlich was eventually pressured into accepting a profit share of only eight percent. Ehrlich resented what he considered as unfair treatment, and his relationship with Behring was thereafter problematic, a situation which later escalated over the issue of the valency of tetanus serum. Ehrlich recognised that the principle of serum therapy had been developed by Behring and Kitasato . But he
36180-441: Was due to an ambition for monetary benefits for the new drug, and with that establishment of his own research institute. Since 1885, he had tried to leave government service and create an independent state-run institute of his own. Following the disappointment, he was released from the University of Berlin and forced to work as Director of the Royal Prussian Institute for Infectious Diseases, a newly established institute, in 1891. He
36381-408: Was effective in humans, his experiments also revealed that when the substance was inoculated into his tuberculosis-infected test guinea pigs, they presented with severe symptoms. This outcome, characterized by an exaggerated immune response, coined the term “Koch’s phenomenon.” This is known as an extreme skin reaction that manifests itself at the BCG vaccination site within a few days after the vaccine
36582-432: Was established in 1896 in Berlin-Steglitz, with Ehrlich as director (which required him to cancel all his contracts with Hoechst). In this function and as honorary professor at Berliner University he had annual earnings of 6,000 marks, approximately the salary of a university professor. In addition to a testing department the institute had a research department. In order to determine the effectiveness of diphtheria antiserum,
36783-570: Was evidence that cattle tuberculosis was transmitted to humans through meat and milk. Upon these reports, Koch conceded that the two bacilli were different but still advocated that cattle tuberculosis was of no health concern. Speaking at the Third International Congress on Tuberculosis , held in London in July 1901, he said that cattle tuberculosis is not dangerous to humans and there is no need for medical attention. He said, "I therefore consider it unnecessary to take any measures against this form of TB. The fight against TB clearly has to concentrate on
36984-430: Was highly variable, a government system was established to guarantee their safety and effectiveness. Beginning 1 April 1895, only government-approved serum could be sold in the German Reich. The testing station for diphtheria serum was provisionally housed at the Institute of Infectious Diseases. At the initiative of Friedrich Althoff, an Institute of Serum Research and Testing ( Institut für Serumforschung und Serumprüfung )
37185-413: Was named its founding director. In 1899 his institute moved to Frankfurt am Main and was renamed the Institute of Experimental Therapy ( Institut für experimentelle Therapie ). One of his important collaborators there was Max Neisser. In 1904, Ehrlich received a full position of honorary professor from the University of Göttingen . In 1906 Ehrlich became the director of the Georg Speyer House in Frankfurt,
37386-404: Was not the optimal medium for bacterial growth, as it did not remain solid at 37 °C, the ideal temperature for growth of most human pathogens. And also many bacteria can hydrolyze gelatin making it a liquid. As suggested to him by his post-doctoral assistant Walther Hesse , who got the idea from his wife Fanny Hesse , in 1881, Koch started using agar to grow and isolate pure cultures. Agar
37587-531: Was of the opinion that he had been the first to develop a serum which could also be used on humans, and that his role in developing the diphtheria serum had been insufficiently acknowledged. Behring, for his part, schemed against Ehrlich at the Prussian Ministry of Culture, and from 1900 on Ehrlich refused to collaborate with him. Von Behring was the sole recipient of the first Nobel Prize in Medicine, in 1901, for contributions to research on diphtheria. Since antiserums were an entirely new type of medicine whose quality
37788-423: Was prohibited from working on tuberculin and from claiming patent rights in any of his subsequent works. Koch initially believed that human ( Mycobacterium tuberculosis ) and cattle tuberculosis bacilli (now called Mycobacterium bovis ) were different pathogens when he made the discovery in 1882. Two years later, he revoked that position and asserted that the two bacilli were the same type. This later assumption
37989-451: Was rejected by the medical profession, which lacked the requisite chemical knowledge. It also meant that there was no suitable professorship in sight for Ehrlich. When a student in Breslau, Ehrlich was given an opportunity by the pathologist Julius Friedrich Cohnheim to conduct extensive research and was also introduced to Robert Koch , who was at the time a district physician in Wollstein, Posen Province. In his spare time, Koch had clarified
38190-417: Was renamed Paul Ehrlich Institute in Ehrlich's honour in 1947. In 1914, Ehrlich signed the Manifesto of the Ninety-Three which was a defence of Germany's World War I politics and militarism. On 17 August 1915 Ehrlich suffered a heart attack and died on 20 August in Bad Homburg vor der Höhe . Wilhelm II the German emperor, wrote in a telegram of condolence, "I, along with the entire civilized world, mourn
38391-458: Was renamed Robert Koch Institute in his honour. The World Health Organization has observed " World Tuberculosis Day " every 24 March since 1982 to commemorate the day Koch discovered the tuberculosis bacterium. Koch's name is one of 23 from the fields of hygiene and tropical medicine featured on the frieze of the London School of Hygiene & Tropical Medicine building in Keppel Street , Bloomsbury . A large marble statue of Koch stands in
38592-454: Was renamed the Royal Prussian Institute of Experimental Therapy ( Königlich Preußisches Institut für Experimentelle Therapie ). The German quality-control methodology was copied by government serum institutes all over the world, and they also obtained the standard serum from Frankfurt. After diphtheria antiserum, tetanus serum and various bactericide serums for use in veterinary medicine were developed in rapid sequence. These were also evaluated at
38793-532: Was retained; in organs with medium saturation, indophenol was reduced, but not alizarin blue. And in areas with low oxygen saturation, both pigments were reduced. With this work, Ehrlich also formulated the conviction which guided his research: that all life processes can be traced to processes of physical chemistry occurring in the cell. In the course of his investigations Ehrlich came across methylene blue , which he regarded as particularly suitable for staining bacteria. Later, Robert Koch also used methylene blue as
38994-478: Was taken as a fact in veterinary practice. Based on it, legislations were made in the US for the inspection of meat and milk. In 1898, an American veterinarian Theobald Smith published a detailed comparative study and found that the tuberculosis bacteria are different based on their structure, growth patterns, and pathogenicity. In addition, he also discovered that there were variations in each type. In his conclusion, he made two important points: By that time, there
39195-406: Was that awarded to Barack Obama in 2009 . Nominations had closed only eleven days after Obama took office as President of the United States , but the actual evaluation occurred over the next eight months. Obama himself stated that he did not feel deserving of the award, or worthy of the company in which it would place him. Past Peace Prize laureates were divided, some saying that Obama deserved
39396-479: Was the director of UNICEF when he accepted the Nobel Peace Prize in 1965 on that organisation's behalf. Although no family matches the Curie family's record, there have been several with two laureates. The Nobel Prize in Physiology or Medicine was awarded to the husband-and-wife team of Gerty Cori and Carl Ferdinand Cori in 1947, and to the husband-and-wife team of May-Britt Moser and Edvard Moser in 2014 (along with John O'Keefe ). The Physics Prize in 1906
39597-434: Was the first to link a specific microorganism with a specific disease, rejecting the idea of spontaneous generation and supporting the germ theory of disease . After graduation in 1866, Koch briefly worked as an assistant in the General Hospital of Hamburg. In October of that year, he moved to Idiot's Hospital of Langenhagen, near Hanover, as a general physician. In 1868, he moved to Neimegk and then to Rakwitz in 1869. As
39798-452: Was then a protectorate of the German Reich. Koch serially examined the Papuan people , the indigenous inhabitants, and their blood samples and noticed they contained Plasmodium parasites, the cause of malaria , but their bouts of malaria were mild or could not even be noticed, i.e. were subclinical . On the contrary, German settlers and Chinese workers, who had been brought to New Guinea, fell sick immediately. The longer they had stayed in
39999-527: Was to find a Therapia sterilisans magna , in other words a treatment that could kill all disease pathogens. As a model for experimental therapy Ehrlich used a guinea pig disease trypanosoma and tested out various chemical substances on laboratory animals. The trypanosomes could indeed be successfully killed with the dye trypan red. Beginning in 1906, he intensively investigated atoxyl and had it tested by Robert Koch along with other arsenic compounds during Koch's sleeping sickness expedition of 1906/07. Although
40200-446: Was unemployed, he privately continued his research on methylene blue. His work on in vivo staining gave him the idea of using it therapeutically. Since the parasite family of Plasmodiidae – which includes the malaria pathogen – can be stained with methylene blue, he thought it could possibly be used in the treatment of malaria. In the case of two patients so treated at the city hospital in Berlin-Moabit, their fever indeed subsided and
40401-423: Was won by J. J. Thomson for showing that electrons are particles, and in 1937 by his son, George Paget Thomson , for showing that they also have the properties of waves . William Henry Bragg and his son, William Lawrence Bragg , shared the Physics Prize in 1915 for inventing X-ray crystallography . Niels Bohr was awarded the Physics Prize in 1922, as was his son, Aage Bohr , in 1975. The Physics Prize
