In September 1821, Wheatstone brought himself into public notice by exhibiting the 'Enchanted Lyre,' or 'Acoucryptophone,' at a music shop at Pall Mall and in the Adelaide Gallery. It consisted of a mimic lyre hung from the ceiling by a cord, and emitting the strains of several instruments – the piano, harp , and dulcimer . In reality it

( Robert Hooke , in his Micrographia , published in 1667, writes: 'I can assure the reader that I have, by the help of a distended wire, propagated the sound to a very considerable distance in an instant, or with as seemingly quick a motion as that of light.' Nor was it essential the wire should be straight; it might be bent into angles. This property is the basis of the mechanical or lover's telephone, said to have been known to

The same year he was awarded the Ampere Medal by the French Society for the Encouragement of National Industry. In 1875 he was created an honorary member of the Institution of Civil Engineers. He was a D.C.L. of Oxford and an LL.D. of Cambridge. While on

In the rostrum he was tongue-tied and incapable, sometimes turning his back on the audience and mumbling to the diagrams on the wall. In the laboratory he felt himself at home, and ever after confined his duties mostly to demonstration. He achieved renown by a great experiment made in 1834 – the measurement of the velocity of electricity in

American and British veterans who served in either World War on French soil, or during the 1944 campaigns to liberate France, may be eligible for appointment as Chevalier of the Legion of Honour, provided they were still living when the honour was approved. Collective appointments can be made to cities, institutions or companies. A total of 64 settlements in France have been decorated, as well as six foreign cities: Liège in 1914, Belgrade in 1920, Luxembourg City in 1957, Volgograd (the World War II 'Stalingrad') in 1984, Algiers in 2004, and London in 2020. French towns display

Wheatstone sent the first message, to which Cooke replied: and "never" said Wheatstone, "did I feel such a tumultuous sensation before, as when, all alone in the still room, I heard the needles click, and as I spelled the words, I felt all the magnitude of the invention pronounced to be practicable beyond cavil or dispute." In spite of this trial, however,

A sound telegraph, in which the signals were given by the strokes of a bell, was also patented by Cooke and Wheatstone in May of that year. Wheatstone's remarkable ingenuity was also displayed in the invention of ciphers. He was responsible for the then unusual Playfair cipher , named after his friend Lord Playfair . It was used by

It consisted of two slender rods, which conveyed the mechanical vibrations to both ears, and is quite different from the electrical microphone of Professor Hughes. In 1823, his uncle, the musical instrument maker, died, and Wheatstone, with his elder brother, William, took over
1397-479: A façade to give political favours, gifts, and concessions. The Légion d'honneur was loosely patterned after a Roman legion , with legionaries , officers , commanders, regional " cohorts " and a grand council. The highest rank was not a Grand Cross but a Grand aigle (Grand Eagle), a rank that wore the insignia common to a Grand Cross. The members were paid, the highest of them extremely generously: Napoleon famously declared, "You call these baubles, well, it

The insignia of the Légion d'honneur bear a resemblance to those of the Ordre de Saint-Louis , which also used a red ribbon. Napoleon originally created this award to ensure political loyalty. The organization would be used as

The following January Alexander Bain took out a patent for an electro-magnetic clock, and he subsequently charged Wheatstone with appropriating his ideas. It appears that Bain worked as a mechanist to Wheatstone from August to December 1840, and he asserted that he had communicated

The actual distance was only one and a half-miles (2.4 km), but spare wire had been inserted in the circuit to increase its length. It was late in the evening before the trial took place. Cooke was in charge at Camden Town, while Robert Stephenson and other gentlemen looked on; and Wheatstone sat at his instrument in

On the night of 8 April 1886, when Gladstone introduced his Bill for Home Rule in Ireland , no fewer than 1,500,000 words were dispatched from the central station at St. Martin's-le-Grand by 100 Wheatstone transmitters. The plan of sending messages by a running strip of paper which actuates the key was originally patented by Alexander Bain in 1846; but Wheatstone, aided by Augustus Stroh, an accomplished mechanician, and an able experimenter,
2032-688: A time was coming when a minister might be asked in Parliament if war had broken out in India, and would reply, 'Wait a minute; I'll just telegraph to the Governor-General, and let you know.' Wheatstone was knighted in 1868, after his completion of the automatic telegraph. He had previously been made a Chevalier of the Legion of Honour . Some thirty-four distinctions and diplomas of home or foreign societies bore witness to his scientific reputation. Since 1836 he had been
2159-646: A visit from William Cooke at his house in Conduit Street on 27 February 1837, which had an important influence on his future. Cooke was an officer in the Madras Army , who, being home on leave, was attending some lectures on anatomy at the University of Heidelberg , where, on 6 March 1836, he witnessed a demonstration with the telegraph of professor Georg Munke , and was so impressed with its importance, that he forsook his medical studies and devoted all his efforts to

In 1840, Wheatstone introduced his chronoscope, for measuring minute intervals of time, which was used in determining the speed of a bullet or the passage of a star. In this apparatus an electric current actuated an electro-magnet, which noted
2540-413: A wire. He cut the wire at the middle, to form a gap which a spark might leap across, and connected its ends to the poles of a Leyden jar filled with electricity. Three sparks were thus produced, one at each end of the wire, and another at the middle. He mounted a tiny mirror on the works of a watch, so that it revolved at a high velocity, and observed the reflections of his three sparks in it. The points of

In practice, in current usage, the order is conferred on entrepreneurs, high-level civil servants , scientists, artists, including famous actors and actresses, sport champions , and others with connections in the executive . Members of the French Parliament cannot receive the order, except for valour in war, and ministers are not allowed to nominate their accountants. Until 2008, French nationals could only enter

As John Munro wrote in 1891, "In 1835, at the Dublin meeting of the British Association, Wheatstone showed that when metals were volatilised in the electric spark, their light, examined through a prism, revealed certain rays which were characteristic of them. Thus
4699-421: The stereoscope . He showed that our impression of solidity is gained by the combination in the mind of two separate pictures of an object taken by both of our eyes from different points of view. Thus, in the stereoscope, an arrangement of lenses or mirrors, two photographs of the same object taken from different points are so combined as to make the object stand out with a solid aspect. Sir David Brewster improved

Francis Ronalds had observed signal retardation in his buried electric telegraph cable (but not his airborne line) in 1816 and outlined its cause to be induction. Wheatstone witnessed these experiments as a youth, which were apparently a stimulus for his own research in telegraphy. Decades later, after

To be promoted to a higher class, one had to perform new eminent services in the interest of France and a set number of years had to pass between appointment and promotion. This was however amended in 2008 when entry became possible at Officer, Commander and Grand Officer levels, as a recognition of "extraordinary careers" ( carrières hors du commun ). In 2009, Simone Veil became

9017-479: The early 20th century. In 1827, Wheatstone introduced his ' kaleidophone ', a device for rendering the vibrations of a sounding body apparent to the eye. It consists of a metal rod, carrying at its end a silvered bead, which reflects a 'spot' of light. As the rod vibrates the spot is seen to describe complicated figures in the air, like a spark whirled about in the darkness. His photometer was probably suggested by this appliance. It enables two lights to be compared by
9144-628: The fashion of the time allowed for decorations to be worn most of the time. The king of Sweden therefore declined the order; it was too common in his eyes. Napoleon's own decorations were captured by the Prussians and were displayed in the Zeughaus (armoury) in Berlin until 1945. Today, they are in Moscow. Louis XVIII changed the appearance of the order, but it was not abolished. To have done so would have angered
9271-515: The fellowships described below: Every year, up to 52 new fellows are elected from the United Kingdom, the rest of the Commonwealth of Nations , and Ireland, which make up around 90% of the society. Each candidate is considered on their merits and can be proposed from any sector of the scientific community. Fellows are elected for life on the basis of excellence in science and are entitled to use
9398-643: The first American was admitted: Thomas Wiltberger Evans , dentist of Napoleon III. In 1870, the defeat of the French Imperial Army in the Franco-Prussian War brought the end of the Empire and the creation of the Third Republic (1871–1940). As France changed, the Légion d'honneur changed as well. The crown was replaced by a laurel and oak wreath. In 1871, during the Paris Commune uprising,
9525-597: The first person to enter the Order at Grand Officer level. Veil was a member of the Académie française , a former Health Minister and President of the European Parliament , as well as an Auschwitz survivor. She was promoted to Grand Cross in 2012. Every year at least five recipients decline the award. Even if they refuse to accept it, they are still included in the order's official membership. The composers Maurice Ravel and Charles Koechlin , for example, declined
9652-440: The first recorded woman, Angélique Duchemin , an old revolutionary of the 1789 uprising against the absolute monarchy, was admitted into the order. On 2 December 1851, President Louis-Napoléon Bonaparte staged a coup d'état with the help of the armed forces. He made himself Emperor of the French exactly one year later on 2 December 1852, after a successful plebiscite . An Imperial crown was added. During Napoleon III 's reign,
9779-578: The flute. Charles, the second son, went to a village school, near Gloucester, and afterwards to several institutions in London. One of them was in Kennington , and kept by a Mrs. Castlemaine, who was astonished at his rapid progress. From another he ran away, but was captured at Windsor , not far from the theatre of his practical telegraph. As a boy he was very shy and sensitive, liking to retreat into an attic, without any other company than his own thoughts. When he
9906-530: The good of the Royal Society of London for Improving Natural Knowledge, and to pursue the ends for which the same was founded; that we will carry out, as far as we are able, those actions requested of us in the name of the Council; and that we will observe the Statutes and Standing Orders of the said Society. Provided that, whensoever any of us shall signify to the President under our hands, that we desire to withdraw from
10033-400: The head of Marianne , surrounded by the legend République Française on a blue enamel ring. The reverse central disc is also in gilt, with a set of crossed tricolores , surrounded by the Légion's motto Honneur et Patrie ('Honour and Fatherland') and its foundation date on a blue enamel ring. The badge is suspended by an enameled laurel and oak wreath. The star (or plaque )
10160-522: The horizon, could be determined, and the apparent solar time obtained. The clock consisted of a spyglass, having a Nicol (double-image) prism for an eyepiece, and a thin plate of selenite for an object-glass. When the tube was directed to the North Pole—that is, parallel to the Earth's axis—and the prism of the eyepiece turned until no colour was seen, the angle of turning, as shown by an index moving with
10287-790: The idea of an electric clock to Wheatstone during that period; but Wheatstone maintained that he had experimented in that direction during May. Bain further accused Wheatstone of stealing his idea of the electro-magnetic printing telegraph; but Wheatstone showed that the instrument was only a modification of his own electro-magnetic telegraph. In 1840, Alexander Bain mentioned to the Mechanics Magazine editor his financial problems. The editor introduced him to Sir Charles Wheatstone. Bain demonstrated his models to Wheatstone, who, when asked for his opinion, said "Oh, I shouldn't bother to develop these things any further! There's no future in them." Three months later Wheatstone demonstrated an electric clock to
10414-481: The individual, the Emperor would take the Legion d'Honneur from his own coat and pin it on the chest of the man. The order was the first modern order of merit . Under the monarchy, such orders were often limited to Roman Catholics, all knights had to be noblemen, and military decorations were restricted to officers . The Légion d'honneur , however, was open to men of all ranks and professions; only merit or bravery counted. The new legionnaire had to be sworn into
10541-415: The instant of an occurrence by means of a pencil on a moving paper. It is said to have been capable of distinguishing 1/7300 part of a second (137 microsecond), and the time a body took to fall from a height of one inch (25 mm). On 26 November 1840, he exhibited his electro-magnetic clock in the library of the Royal Society, and propounded a plan for distributing the correct time from a standard clock to
10668-414: The key, the current deflected the needle to one side or the other. There were five separate circuits actuating five different needles. The latter were pivoted in rows across the middle of a dial shaped like a diamond, and having the letters of the alphabet arranged upon it in such a way that a letter was literally pointed out by the current deflecting two of the needles towards it. An experimental line, with
10795-456: The kind of metals which formed the sparking points could be determined by analysing the light of the spark. This suggestion has been of great service in spectrum analysis, and as applied by Robert Bunsen , Gustav Robert Kirchhoff , and others, has led to the discovery of several new elements, such as rubidium and thallium , as well as increasing our knowledge of the heavenly bodies." Wheatstone abandoned his idea of transmitting intelligence by
10922-490: The line. Their circuit was eventually extended to Slough in 1841, and was publicly exhibited at Paddington as a marvel of science, which could transmit fifty signals a distance of 280,000 miles per minute (7,500 km/s). The price of admission was a shilling (£0.05), and in 1844 one fascinated observer recorded the following: It is perfect from the terminus of the Great Western as far as Slough – that is, eighteen miles;
11049-528: The mechanical vibration of rods, and took up the electric telegraph . In 1835 he lectured on the system of Baron Schilling , and declared that the means were already known by which an electric telegraph could be made of great service to the world. He made experiments with a plan of his own, and not only proposed to lay an experimental line across the Thames, but to establish it on the London and Birmingham Railway. Before these plans were carried out, however, he received
11176-403: The medal is plain red. The badge or star is not usually worn, except at the time of the decoration ceremony or on a dress uniform or formal wear . Instead, one normally wears the ribbon or rosette on their suit. For less formal occasions, recipients wear a simple stripe of thread sewn onto the lapel (red for chevaliers and officiers , silver for commandeurs ). Except when wearing
11303-405: The medal, whatever the Légion d'honneur rank and the military rank of the bearer. This is not mandatory with the ribbon. In practice, however, this is rarely done. There is not a single, complete list of all the members of the Legion in chronological order. The number is estimated at one million, including about 2,900 Knights Grand Cross. French nationals, men and women, can be received into
11430-417: The messages it brings, so that if no-one attended to the bell,....the message would not be lost. This is effected by the electrical fluid causing a little hammer to strike the letter which presents itself, the letter which is raised hits some manifold writing paper (a new invention, black paper which, if pressed, leaves an indelible black mark), by which means the impression is left on white paper beneath. This
11557-460: The method would not act, and produced his own experimental telegraph. Finally, Cooke proposed that they should enter into a partnership, but Wheatstone was at first reluctant to comply. He was a well-known man of science, and had meant to publish his results without seeking to make capital of them. Cooke, on the other hand, declared that his sole object was to make a fortune from the scheme. In May they agreed to join their forces, Wheatstone contributing
11684-509: The militaries of several nations through at least World War I, and is known to have been used during World War II by British intelligence services. It was initially resistant to cryptanalysis , but methods were eventually developed to break it. He also became involved in the interpretation of cipher manuscripts in the British Museum. He devised a cryptograph or machine for turning a message into cipher which could only be interpreted by putting
11811-423: The needle telegraph a joint production. If it had mainly been invented by Wheatstone, it was chiefly introduced by Cooke. Their respective shares in the undertaking might be compared to that of an author and his publisher, but for the fact that Cooke himself had a share in the actual work of invention. From 1836 to 1837 Wheatstone had thought a good deal about submarine telegraphs, and in 1840 he gave evidence before
11938-525: The needles. Of these, the single-needle instrument, requiring only one wire, is still in use. The development of the telegraph may be gathered from two facts. In 1855, the death of the Emperor Nicholas at St. Petersburg , about one o'clock in the afternoon, was announced in the House of Lords a few hours later. The result of The Oaks of 1890 was received in New York fifteen seconds after the horses passed
12065-464: The order. Members convicted of a misdemeanour ( délit in French) can be dismissed as well, although this is not automatic. Wearing the decoration of the Légion d'honneur without having the right to do so is a serious offence. Wearing the ribbon or rosette of a foreign order is prohibited if that ribbon is mainly red, like the ribbon of the Legion of Honour. French military personnel in uniform must salute other military members in uniform wearing
12192-509: The post nominal letters HonFRS . Statute 12 is a legacy mechanism for electing members before official honorary membership existed in 1997. Fellows elected under statute 12 include David Attenborough (1983) and John Palmer, 4th Earl of Selborne (1991). The Council of the Royal Society can recommend members of the British royal family for election as Royal Fellow of the Royal Society . As of 2023 there are four royal fellows: Elizabeth II
12319-539: The prism over a graduated limb, gave the hour of day. The device is of little service in a country where watches are reliable; but it formed part of the equipment of the 1875–1876 North Polar expedition commanded by Captain Nares. In 1843 Wheatstone communicated an important paper to the Royal Society, entitled 'An Account of Several New Processes for Determining the Constants of a Voltaic Circuit.' It contained an exposition of
12446-546: The proposal is being made. There is no limit on the number of nominations made each year. In 2015, there were 654 candidates for election as Fellows and 106 candidates for Foreign Membership. The Council of the Royal Society oversees the selection process and appoints 10 subject area committees, known as Sectional Committees, to recommend the strongest candidates for election to the Fellowship. The final list of up to 52 Fellowship candidates and up to 10 Foreign Membership candidates
12573-556: The relative brightness of their reflections in a silvered bead, which describes a narrow ellipse, so as to draw the spots into parallel lines. In 1828, Wheatstone improved the German wind instrument, called the Mundharmonika , creating the symphonium (or symphonion ), a mouth-blown free-reed instrument with a logical layout of button keys, patented on 19 December 1829, prefiguring the bellows-blown English concertina. The portable harmonium
12700-446: The scientific, and Cooke the administrative talent. The deed of partnership was dated 19 November 1837. A joint patent was taken out for their inventions, including the five-needle telegraph of Wheatstone, and an alarm worked by a relay, in which the current, by dipping a needle into mercury, completed a local circuit, and released the detent of a clockwork. The five-needle telegraph, which was mainly, if not entirely, due to Wheatstone,
12827-419: The scullery behind his father's house. In constructing the battery, the boy philosophers ran short of money to procure the requisite copper-plates. They had only a few copper coins left. A happy thought occurred to Charles, who was the leading spirit in these researches, 'We must use the pennies themselves,' said he, and the battery was soon complete. At Christchurch, Marylebone , on 12 February 1847, Wheatstone
12954-558: The signals of the message are first punched out on a strip of paper ( punched tape ), which is then passed through the sending-key, and controls the signal currents. By substituting a mechanism for the hand in sending the message, he was able to telegraph about 100 words a minute, or five times the ordinary rate. In the Postal Telegraph service this apparatus is employed for sending Press telegrams, and it has recently been so much improved, that messages are now sent from London to Bristol at
13081-452: The stereoscope by dispensing with the mirrors, and bringing it into its existing form with lenses. The ' pseudoscope ' (Wheatstone coined the term from the Greek ψευδίς σκοπειν) was introduced in 1852, and is in some sort the reverse of the stereoscope, since it causes a solid object to seem hollow, and a nearer one to be farther off; thus, a bust appears to be a mask, and a tree growing outside of
13208-588: The subject of the Atlantic cables, and in 1864 he was one of the experts who advised the Atlantic Telegraph Company on the construction of the successful lines of 1865 and 1866. In 1870 the electric telegraph lines of the United Kingdom, worked by different companies, were transferred to the Post Office, and placed under Government control. Wheatstone further invented the automatic transmitter , in which
13335-420: The surprise of the bookseller, he coveted a volume on the discoveries of Volta in electricity, but not having the price, he saved his pennies and secured the volume. It was written in French, and so he was obliged to save again, until he could buy a dictionary. Then he began to read the volume, and, with the help of his elder brother, William, to repeat the experiments described in it, with a home-made battery, in
13462-459: The telegraph as a useful undertaking which promised to be of national importance, and to Wheatstone that of having by his researches prepared the public to receive it. They concluded with the words: 'It is to the united labours of two gentlemen so well qualified for mutual assistance that we must attribute the rapid progress which this important invention has made during five years since they have been associated.' The decision, however vague, pronounces
13589-439: The telegraph had been commercialised, Michael Faraday described how the velocity of an electric field in a submarine wire, coated with insulator and surrounded with water, is only 144,000 miles per second (232,000 km/s), or still less. Wheatstone's device of the revolving mirror was afterwards employed by Léon Foucault and Hippolyte Fizeau to measure the relative speeds of light in air versus water , and later to measure
13716-406: The time, he had only to compare that with the length of half the wire, and he could find the velocity of electricity. His results gave a calculated velocity of 288,000 miles per second, i.e. faster than what we now know to be the speed of light (299,792.458 kilometres per second (186,000 mi/s)), but were nonetheless an interesting approximation. It was already appreciated by some scientists that
13843-472: The time, sometimes even changed multiple times during one historical era. The badge of the Légion is shaped as a five-armed "Maltese Asterisk ", using five distinctive "arrowhead" shaped arms inspired by the Maltese Cross . The badge is rendered in gilt (in silver for chevalier) enameled white, with an enameled laurel and oak wreath between the arms. The obverse central disc is in gilt, featuring
13970-532: The type revolved a hammer, actuated by the current, pressed the required letter on the paper. The introduction of the telegraph had so far advanced that, on 2 September 1845, the Electric Telegraph Company was registered, and Wheatstone, by his deed of partnership with Cooke, received a sum of £33,000 for the use of their joint inventions. In 1859 Wheatstone was appointed by the Board of Trade to report on
14097-565: The well known balance for measuring the electrical resistance of a conductor, which still goes by the name of Wheatstone's Bridge or balance, although it was first devised by Samuel Hunter Christie , of the Royal Military Academy, Woolwich, who published it in the Philosophical Transactions for 1833. The method was neglected until Wheatstone brought it into notice. His paper abounds with simple and practical formulae for
14224-465: The winning-post. In 1841 a difference arose between Cooke and Wheatstone as to the share of each in the honour of inventing the telegraph. The question was submitted to the arbitration of the famous engineer, Marc Isambard Brunel , on behalf of Cooke, and Professor Daniell , of King's College, the inventor of the Daniell cell , on the part of Wheatstone. They awarded to Cooke the credit of having introduced
14351-415: The wire were so arranged that if the sparks were instantaneous, their reflections would appear in one straight line; but the middle one was seen to lag behind the others, because it was an instant later. The electricity had taken a certain time to travel from the ends of the wire to the middle. This time was found by measuring the amount of lag, and comparing it with the known velocity of the mirror. Having got
14478-557: The wires being in some places underground in tubes, and in others high up in the air, which last, he says, is by far the best plan. We asked if the weather did not affect the wires, but he said not; a violent thunderstorm might ring a bell, but no more. We were taken into a small room (we being Mrs Drummond , Miss Philips, Harry Codrington and myself – and afterwards the Milmans and Mr Rich) where were several wooden cases containing different sorts of telegraphs. In one sort every word
14605-602: The work of introducing the telegraph. He returned to London soon after, and was able to exhibit a telegraph with three needles in January 1837. Feeling his want of scientific knowledge, he consulted Michael Faraday and Peter Roget (then secretary of the Royal Society ): Roget sent him to Wheatstone. At a second interview, Cooke told Wheatstone of his intention to bring out a working telegraph, and explained his method. Wheatstone, according to his own statement, remarked to Cooke that
14732-451: Was a mere sounding box, and the cord was a steel rod that conveyed the vibrations of the music from the several instruments which were played out of sight and ear-shot. At this period Wheatstone made numerous experiments on sound and its transmission. Some of his results are preserved in Thomson's Annals of Philosophy for 1823. He recognised that sound is propagated by waves or oscillations of
14859-406: Was about fourteen years old he was apprenticed to his uncle and namesake, a maker and seller of musical instruments at 436 Strand, London; but he showed little taste for handicraft or business, and loved better to study books. His father encouraged him in this, and finally took him out of the uncle's charge. At the age of fifteen, Wheatstone translated French poetry, and wrote two songs, one of which
14986-566: Was full of animation. Sir Henry Taylor tells us that he once observed Wheatstone at an evening party in Oxford earnestly holding forth to Lord Palmerston on the capabilities of his telegraph. 'You don't say so!' exclaimed the statesman. 'I must get you to tell that to the Lord Chancellor .' And so saying, he fastened the electrician on Lord Westbury , and effected his escape. A reminiscence of this interview may have prompted Palmerston to remark that
15113-434: Was given to his uncle, who published it without knowing it as his nephew's composition. Some lines of his on the lyre became the motto of an engraving by Bartolozzi . He often visited an old book-stall in the vicinity of Pall Mall , which was then a dilapidated and unpaved thoroughfare. Most of his pocket-money was spent in purchasing the books which had taken his fancy, whether fairy tales, history, or science. One day, to
15240-416: Was married to Emma West. She was the daughter of a Taunton tradesman, and of handsome appearance. She died in 1866, leaving a family of five young children to his care. His domestic life was quiet and uneventful. Though silent and reserved in public, Wheatstone was a clear and voluble talker in private, if taken on his favourite studies, and his small but active person, his plain but intelligent countenance,
15367-421: Was not a Royal Fellow, but provided her patronage to the society, as all reigning British monarchs have done since Charles II of England . Prince Philip, Duke of Edinburgh (1951) was elected under statute 12, not as a Royal Fellow. The election of new fellows is announced annually in May, after their nomination and a period of peer-reviewed selection. Each candidate for Fellowship or Foreign Membership
15494-405: Was similar to that of Schilling, and based on the principle enunciated by Ampère – that is to say, the current was sent into the line by completing the circuit of the battery with a make and break key, and at the other end it passed through a coil of wire surrounding a magnetic needle free to turn round its centre. According as one pole of the battery or the other was applied to the line by means of
15621-420: Was slow to accept his indirect political responsibility, which caused his eventual resignation on 2 December 1887. During World War I , some 55,000 decorations were conferred, 20,000 of which went to foreigners. The large number of decorations resulted from the new posthumous awards authorised in 1918. Traditionally, membership in the Légion d'honneur could not be awarded posthumously. The establishment of
15748-399: Was spelt, and as each letter was placed in turn in a particular position, the machinery caused the electric fluid to run down the line, where it made the letter show itself at Slough, by what machinery he could not undertake to explain. After each word came a sign from Slough, signifying "I understand", coming certainly in less than one second from the end of the word......Another prints
15875-411: Was the 'Polar clock,' exhibited at the meeting of the British Association in 1848. It is based on the fact discovered by Sir David Brewster , that the light of the sky is polarised in a plane at an angle of ninety degrees from the position of the sun. It follows that by discovering that plane of polarisation, and measuring its azimuth with respect to the north, the position of the sun, although beneath
16002-525: Was the first to bring the idea into successful operation. This system is often referred to as the Wheatstone Perforator and is the forerunner of the stock market ticker tape . Stereopsis was first described by Wheatstone in 1838. In 1840 he was awarded the Royal Medal of the Royal Society for his explanation of binocular vision , a research which led him to make stereoscopic drawings and construct
16129-521: Was the most ingenious of all, and apparently Mr. Wheatstone's favourite; he was very good-natured in explaining but understands it so well himself that he cannot feel how little we know about it, and goes too fast for such ignorant folk to follow him in everything. Mrs Drummond told me he is wonderful for the rapidity with which he thinks and his power of invention; he invents so many things that he cannot put half his ideas into execution, but leaves them to be picked up and used by others, who get
