MCI Mail was one of the first commercial email services in the United States and one of the largest telecommunication services in the world. Operated by MCI Communications Corp. from 1983 to 2003, MCI Mail offered its customers a low cost and effective solution for sending and receiving electronic mail.
99-503: The MCI Mail service was launched on September 23, 1983, in Washington, D.C., during a press conference that was hosted by MCI's founder and Chairman, William G. McGowan . MCI Mail was the first commercial email service to use the Internet , in 1989. The service was officially decommissioned by MCI at 11:59 p.m. ET on June 30, 2003. William G. McGowan , MCI's founder and chairman, joined
198-453: A 4-Hour delivery option. The 4-hour service in particular was attractive as no one else offered the ability to print a document and have it delivered in this time frame. There were 15 print facilities around the U.S. which offered this service. The most popular locations were New York, Washington, D.C., and Los Angeles. At one point there was a print facility in Hawaii and they also ventured into
297-561: A diplomatic cable , is a confidential communication between a diplomatic mission and the foreign ministry of its parent country. These continue to be called telegrams or cables regardless of the method used for transmission. Passing messages by signalling over distance is an ancient practice. One of the oldest examples is the signal towers of the Great Wall of China . In 400 BC , signals could be sent by beacon fires or drum beats . By 200 BC complex flag signalling had developed, and by
396-477: A PC. These included Lotus Express, Norton Commander 's MCI Mail utility, MailRoom from Sierra Solutions, Emma, and MCI's own MCI Mail Express and Express Lite. The email facility in Microsoft Bob also used MCI Mail. Customers could send hard-copy MCI Letter messages to postal addresses. These were laser printed at an MCI Mail print site, placed in an envelope and mailed via the U.S. Postal Service . The cost
495-448: A code by itself. The term heliostat is sometimes used as a synonym for heliograph because of this origin. The Colomb shutter ( Bolton and Colomb , 1862) was originally invented to enable the transmission of morse code by signal lamp between Royal Navy ships at sea. The heliograph was heavily used by Nelson A. Miles in Arizona and New Mexico after he took over command (1886) of
594-410: A distance and cablegram means something written via a cable, whereas telegraph implies the process of writing at a distance. Later, a Telex was a message sent by a Telex network, a switched network of teleprinters similar to a telephone network. A wirephoto or wire picture was a newspaper picture that was sent from a remote location by a facsimile telegraph . A diplomatic telegram, also known as
693-466: A distance of a quarter of a mile. In the 1890s inventor Nikola Tesla worked on an air and ground conduction wireless electric power transmission system , similar to Loomis', which he planned to include wireless telegraphy. Tesla's experiments had led him to incorrectly conclude that he could use the entire globe of the Earth to conduct electrical energy and his 1901 large scale application of his ideas,
792-473: A few days, sometimes taking all day to send a message despite the use of the highly sensitive mirror galvanometer developed by William Thomson (the future Lord Kelvin ) before being destroyed by applying too high a voltage. Its failure and slow speed of transmission prompted Thomson and Oliver Heaviside to find better mathematical descriptions of long transmission lines . The company finally succeeded in 1866 with an improved cable laid by SS Great Eastern ,
891-734: A few features available, as well as hints and tricks for using MCI Mail. Long before spam became a problem on the Internet, Oppenheimer broadcast the planned table of contents, giving the recipients the opportunity to opt-out of receiving the newsletter. The final edition of the PEN newsletter included articles on Concert Packet Switching Service for MCI Mail, MCI Mail Telephone update, Cellular Access to MCI Mail, List of Access Cellular Numbers, Logon Procedures, X.400 Access via Frame Relay, MCI Never Busy Fax, Mailroom/Mailplus & MIME, internetMCI software, domainTNG, Newsgroups/Lists, and Web Surfing via MCI Mail. In
990-540: A message was relayed 640 km (400 mi) in four hours. Miles' enemies used smoke signals and flashes of sunlight from metal, but lacked a sophisticated telegraph code. The heliograph was ideal for use in the American Southwest due to its clear air and mountainous terrain on which stations could be located. It was found necessary to lengthen the morse dash (which is much shorter in American Morse code than in
1089-489: A modification of surveying equipment ( Gauss , 1821). Various uses of mirrors were made for communication in the following years, mostly for military purposes, but the first device to become widely used was a heliograph with a moveable mirror ( Mance , 1869). The system was used by the French during the 1870–71 siege of Paris , with night-time signalling using kerosene lamps as the source of light. An improved version (Begbie, 1870)

The new material was tested by Michael Faraday and in 1845 Wheatstone suggested that it should be used on the cable planned between Dover and Calais by John Watkins Brett . The idea was proved viable when the South Eastern Railway company successfully tested a three-kilometre (two-mile) gutta-percha insulated cable with telegraph messages to
1287-410: A predecessor to MCI Communications . In his role as chairman, McGowan raised capital for the growing company and set up fifteen of the seventeen regional carriers that would form the basis of MCI's initial communications network. In 1971, he executed a reorganization of Microwave Communications of America and its seventeen subsidiaries to form MCI Communications. In his role at MCI, McGowan established
1386-414: A reputation as a hard worker by routinely working fifteen-hour days. He was also a three-pack-a-day smoker and drank over twenty cups of coffee each day until his first heart attack. As leader of MCI, he labored for several years to gain the financing and regulator approvals required to begin full operations. Following the filing of MCI's 1974 lawsuit against AT&T , McGowan began cooperation with
1485-596: A ship off the coast of Folkestone . The cable to France was laid in 1850 but was almost immediately severed by a French fishing vessel. It was relaid the next year and connections to Ireland and the Low Countries soon followed. Getting a cable across the Atlantic Ocean proved much more difficult. The Atlantic Telegraph Company , formed in London in 1856, had several failed attempts. A cable laid in 1858 worked poorly for
1584-440: A single-needle telegraph was adapted to indicate just two messages: "Line Clear" and "Line Blocked". The signaller would adjust his line-side signals accordingly. As first implemented in 1844 each station had as many needles as there were stations on the line, giving a complete picture of the traffic. As lines expanded, a sequence of pairs of single-needle instruments were adopted, one pair for each block in each direction. Wigwag
1683-640: A substantial distance was by Ronalds in 1816 using an electrostatic generator . Ronalds offered his invention to the British Admiralty , but it was rejected as unnecessary, the existing optical telegraph connecting the Admiralty in London to their main fleet base in Portsmouth being deemed adequate for their purposes. As late as 1844, after the electrical telegraph had come into use, the Admiralty's optical telegraph
1782-418: A system for mass distributing information on current price of publicly listed companies. In a punched-tape system, the message is first typed onto punched tape using the code of the telegraph system—Morse code for instance. It is then, either immediately or at some later time, run through a transmission machine which sends the message to the telegraph network. Multiple messages can be sequentially recorded on
1881-503: A system of communication that would allow the central government to receive intelligence and to transmit orders in the shortest possible time. On 2 March 1791, at 11 am, they sent the message "si vous réussissez, vous serez bientôt couverts de gloire" (If you succeed, you will soon bask in glory) between Brulon and Parce, a distance of 16 kilometres (10 mi). The first means used a combination of black and white panels, clocks, telescopes, and codebooks to send their message. In 1792, Claude
1980-534: A telefax machine. In 1855, an Italian priest, Giovanni Caselli , also created an electric telegraph that could transmit images. Caselli called his invention " Pantelegraph ". Pantelegraph was successfully tested and approved for a telegraph line between Paris and Lyon . In 1881, English inventor Shelford Bidwell constructed the scanning phototelegraph that was the first telefax machine to scan any two-dimensional original, not requiring manual plotting or drawing. Around 1900, German physicist Arthur Korn invented
2079-461: A telegraph between St Petersburg and Kronstadt , but it was never completed. The first operative electric telegraph ( Gauss and Weber , 1833) connected Göttingen Observatory to the Institute of Physics about 1 km away during experimental investigations of the geomagnetic field. The first commercial telegraph was by Cooke and Wheatstone following their English patent of 10 June 1837. It

In 2002, McGowan was inducted into the Wireless Hall of Fame for his dedication to the cellular industry. Telegraphy#Telex Telegraphy is the long-distance transmission of messages where the sender uses symbolic codes, known to
2277-448: A year of operation, his consulting agency branched out into venture capital . In the role of venture capitalist, McGowan dealt with firms developing ultrasonic cleaning technology and electro-mechanical devices. In 1968, McGowan was contacted by MCI due to his expertise in raising venture capital. Based on this contact, he made a US$ 50,000 investment in the fledgling business and was made chairman of Microwave Communications of America,
2376-465: Is a form of flag signalling using a single flag. Unlike most forms of flag signalling, which are used over relatively short distances, wigwag is designed to maximise the distance covered—up to 32 km (20 mi) in some cases. Wigwag achieved this by using a large flag—a single flag can be held with both hands unlike flag semaphore which has a flag in each hand—and using motions rather than positions as its symbols since motions are more easily seen. It
2475-512: Is a telegraph consisting of a line of stations in towers or natural high points which signal to each other by means of shutters or paddles. Signalling by means of indicator pointers was called semaphore . Early proposals for an optical telegraph system were made to the Royal Society by Robert Hooke in 1684 and were first implemented on an experimental level by Sir Richard Lovell Edgeworth in 1767. The first successful optical telegraph network
2574-458: Is a telegraph machine that can send messages from a typewriter-like keyboard and print incoming messages in readable text with no need for the operators to be trained in the telegraph code used on the line. It developed from various earlier printing telegraphs and resulted in improved transmission speeds. The Morse telegraph (1837) was originally conceived as a system marking indentations on paper tape. A chemical telegraph making blue marks improved
2673-560: Is a telegraph system using reflected sunlight for signalling. It was mainly used in areas where the electrical telegraph had not been established and generally used the same code. The most extensive heliograph network established was in Arizona and New Mexico during the Apache Wars . The heliograph was standard military equipment as late as World War II . Wireless telegraphy developed in the early 20th century became important for maritime use, and

DePaul University in Chicago has two science and research buildings named for
2871-447: Is that it permits duplex communication. The Wheatstone tape reader was capable of a speed of 400 words per minute. A worldwide communication network meant that telegraph cables would have to be laid across oceans. On land cables could be run uninsulated suspended from poles. Underwater, a good insulator that was both flexible and capable of resisting the ingress of seawater was required. A solution presented itself with gutta-percha ,

A study of these demonstrations of radio, with scientists trying to work out how a phenomenon predicted to have a short range could transmit "over the horizon", led to the discovery of a radio reflecting layer in the Earth's atmosphere in 1902, later called the ionosphere . Radiotelegraphy proved effective for rescue work in sea disasters by enabling effective communication between ships and from ship to shore. In 1904, Marconi began

3168-499: The First Macedonian War . Nothing else that could be described as a true telegraph existed until the 17th century. Possibly the first alphabetic telegraph code in the modern era is due to Franz Kessler who published his work in 1616. Kessler used a lamp placed inside a barrel with a moveable shutter operated by the signaller. The signals were observed at a distance with the newly invented telescope. An optical telegraph
3267-582: The Han dynasty (200 BC – 220 AD) signallers had a choice of lights, flags, or gunshots to send signals. By the Tang dynasty (618–907) a message could be sent 1,100 kilometres (700 mi) in 24 hours. The Ming dynasty (1368–1644) added artillery to the possible signals. While the signalling was complex (for instance, different-coloured flags could be used to indicate enemy strength), only predetermined messages could be sent. The Chinese signalling system extended well beyond
3366-519: The London and Birmingham Railway line's chief engineer. The messages were for the operation of the rope-haulage system for pulling trains up the 1 in 77 bank. The world's first permanent railway telegraph was completed in July 1839 between London Paddington and West Drayton on the Great Western Railway with an electric telegraph using a four-needle system.

Bill was active in Ashley Boy Scouts and his troop which included his friends, Tim Klinges, Manus Cooney, Dave Cooney and George Frees, was one of the first group of Boy Scouts to go to Camp St. Andrew before it opened publicly in Tunkhannock, PA. Bill's brother, Monsignor Andrew J. McGowan eventually ran Camp St. Andrew. After graduating from Hanover High School Bill joined
3762-465: The 1850s until well into the 20th century, British submarine cable systems dominated the world system. This was set out as a formal strategic goal, which became known as the All Red Line . In 1896, there were thirty cable-laying ships in the world and twenty-four of them were owned by British companies. In 1892, British companies owned and operated two-thirds of the world's cables and by 1923, their share
3861-530: The 1890s saw the discovery and then development of a newly understood phenomenon into a form of wireless telegraphy , called Hertzian wave wireless telegraphy, radiotelegraphy, or (later) simply " radio ". Between 1886 and 1888, Heinrich Rudolf Hertz published the results of his experiments where he was able to transmit electromagnetic waves (radio waves) through the air, proving James Clerk Maxwell 's 1873 theory of electromagnetic radiation . Many scientists and inventors experimented with this new phenomenon but

Robert Harcharik was the President of Tymnet when he was recruited to MCI to develop what he called a "digital postoffice." Eventually this service became known as MCI Mail. Harcharik recruited and organized a development team that included Vint Cerf . In late 1982, Vint Cerf , one of the original designers of the MCI email service,
4653-438: The consensus was that these new waves (similar to light) would be just as short range as light, and, therefore, useless for long range communication. At the end of 1894, the young Italian inventor Guglielmo Marconi began working on the idea of building a commercial wireless telegraphy system based on the use of Hertzian waves (radio waves), a line of inquiry that he noted other inventors did not seem to be pursuing. Building on

Upon approval by the FCC to begin working, McGowan knew he had to keep up with
4950-458: The earliest electrical telegraphs. A telegraph message sent by an electrical telegraph operator or telegrapher using Morse code (or a printing telegraph operator using plain text) was known as a telegram. A cablegram was a message sent by a submarine telegraph cable, often shortened to "cable" or "wire". The suffix -gram is derived from ancient Greek: γραμμα ( gramma ), meaning something written, i.e. telegram means something written at

This is to be distinguished from semaphore , which merely transmits messages. Smoke signals, for instance, are to be considered semaphore, not telegraph. According to Morse, telegraph dates only from 1832 when Pavel Schilling invented one of

This shift rocked MCI Mail's electronic message delivery and receiving rates, as customers were more inclined to use services available to them with no charge. In addition to an increase in industry competition, the modernization of the fax machine proved more efficient and valuable to customers than MCI Mail's services. These industry advances contributed to

Use of the heliograph declined from 1915 onwards, but remained in service in Britain and British Commonwealth countries for some time. Australian forces used the heliograph as late as 1942 in the Western Desert Campaign of World War II . Some form of heliograph was used by the mujahideen in the Soviet–Afghan War (1979–1989). A teleprinter

Tacticus's system had water filled pots at the two signal stations which were drained in synchronisation. Annotation on a floating scale indicated which message was being sent or received. Signals sent by means of torches indicated when to start and stop draining to keep
6732-519: The recipient, rather than a physical exchange of an object bearing the message. Thus flag semaphore is a method of telegraphy, whereas pigeon post is not. Ancient signalling systems, although sometimes quite extensive and sophisticated as in China, were generally not capable of transmitting arbitrary text messages. Possible messages were fixed and predetermined, so such systems are thus not true telegraphs. The earliest true telegraph put into widespread use
6831-419: The same run of tape. The advantage of doing this is that messages can be sent at a steady, fast rate making maximum use of the available telegraph lines. The economic advantage of doing this is greatest on long, busy routes where the cost of the extra step of preparing the tape is outweighed by the cost of providing more telegraph lines. The first machine to use punched tape was Bain's teleprinter (Bain, 1843), but

By 1989, a gateway to the Internet was also provided. MCI Mail users were assigned an email address of either their MCI Mail ID @mcimail.com (e.g. 2180241@mcimail.com), their user name @mcimail.com (e.g. bsmith@mcimail.com), or their formal name @mcimail.com (e.g. Bob_Smith@mcimail.com). Several email software products were developed to facilitate email handling from
7029-451: The speed of recording ( Bain , 1846), but was delayed by a patent challenge from Morse. The first true printing telegraph (that is printing in plain text) used a spinning wheel of types in the manner of a daisy wheel printer ( House , 1846, improved by Hughes , 1855). The system was adopted by Western Union . Early teleprinters used the Baudot code , a five-bit sequential binary code. This

However, Great Britain and the British Empire continued to use the Cooke and Wheatstone system, in some places as late as the 1930s. Likewise, the United States continued to use American Morse code internally, requiring translation operators skilled in both codes for international messages. Railway signal telegraphy
7227-462: The synchronisation. None of the signalling systems discussed above are true telegraphs in the sense of a system that can transmit arbitrary messages over arbitrary distances. Lines of signalling relay stations can send messages to any required distance, but all these systems are limited to one extent or another in the range of messages that they can send. A system like flag semaphore , with an alphabetic code, can certainly send any given message, but
7326-554: The system is designed for short-range communication between two persons. An engine order telegraph , used to send instructions from the bridge of a ship to the engine room, fails to meet both criteria; it has a limited distance and very simple message set. There was only one ancient signalling system described that does meet these criteria. That was a system using the Polybius square to encode an alphabet. Polybius (2nd century BC) suggested using two successive groups of torches to identify
7425-602: The system saw only limited use. Later versions of Bain's system achieved speeds up to 1000 words per minute, far faster than a human operator could achieve. The first widely used system (Wheatstone, 1858) was first put into service with the British General Post Office in 1867. A novel feature of the Wheatstone system was the use of bipolar encoding . That is, both positive and negative polarity voltages were used. Bipolar encoding has several advantages, one of which
7524-523: The transmitter and receiver, Marconi was able, by early 1896, to transmit radio far beyond the short ranges that had been predicted. Having failed to interest the Italian government, the 22-year-old inventor brought his telegraphy system to Britain in 1896 and met William Preece , a Welshman, who was a major figure in the field and Chief Engineer of the General Post Office . A series of demonstrations for
7623-445: The two stations to form a complete electrical circuit or "loop". In 1837, however, Carl August von Steinheil of Munich , Germany , found that by connecting one leg of the apparatus at each station to metal plates buried in the ground, he could eliminate one wire and use a single wire for telegraphic communication. This led to speculation that it might be possible to eliminate both wires and therefore transmit telegraph signals through
7722-562: The wife of McGowan. On April 25, 1987, McGowan underwent a heart transplant at UPMC Presbyterian in Pittsburgh, Pennsylvania. On December 21, 1986, McGowan experienced a heart attack . His medical problems resulted in his receiving a heart transplant on April 25, 1987. McGowan returned to his duties as MCI chairman after a six-month recovery, where he remained until his death on June 8, 1992, from another heart attack. McGowan's philanthropy continues on in many forms. He established what
7821-412: Was $ 2 for up to 3 pages for an MCI Letter, and $ 9 for an Overnight Letter. The service was attractive because there were few affordable letter-quality laser printers available to consumers at the time. Most consumers could only afford low quality dot matrix printers , which were not suitable for business correspondence. It also saved a trip to the post office. Prior to 1996, the service also allowed users
7920-459: Was a competitor to electrical telegraphy using submarine telegraph cables in international communications. Telegrams became a popular means of sending messages once telegraph prices had fallen sufficiently. Traffic became high enough to spur the development of automated systems— teleprinters and punched tape transmission. These systems led to new telegraph codes , starting with the Baudot code . However, telegrams were never able to compete with
8019-481: Was a telegraph code developed for use on the French telegraph using a five-key keyboard ( Baudot , 1874). Teleprinters generated the same code from a full alphanumeric keyboard. A feature of the Baudot code, and subsequent telegraph codes, was that, unlike Morse code, every character has a code of the same length making it more machine friendly. The Baudot code was used on the earliest ticker tape machines ( Calahan , 1867),
8118-520: Was also provided via Infonet's dedicated data network. MCI Mail branded this access service: MCI Mail Global Access. The service was primarily sold using a third-party "agency program". Agents were paid a commission on usage. One of these agents, Gary Oppenheimer, created what is believed to be the first electronically delivered newsletter. Called the PEN (Periodic Electronic Newsletter), it was published from August 1985 until November 1996, and provided both customers and many MCI employees with information on
8217-469: Was appointed Ingénieur-Télégraphiste and charged with establishing a line of stations between Paris and Lille , a distance of 230 kilometres (140 mi). It was used to carry dispatches for the war between France and Austria. In 1794, it brought news of a French capture of Condé-sur-l'Escaut from the Austrians less than an hour after it occurred. A decision to replace the system with an electric telegraph
8316-401: Was coined by the French inventor of the semaphore telegraph , Claude Chappe , who also coined the word semaphore . A telegraph is a device for transmitting and receiving messages over long distances, i.e., for telegraphy. The word telegraph alone generally refers to an electrical telegraph . Wireless telegraphy is transmission of messages over radio with telegraphic codes. Contrary to
8415-414: Was demonstrated on the London and Birmingham Railway in July of the same year. In July 1839, a five-needle, five-wire system was installed to provide signalling over a record distance of 21 km on a section of the Great Western Railway between London Paddington station and West Drayton. However, in trying to get railway companies to take up his telegraph more widely for railway signalling , Cooke
8514-421: Was developed in Britain from the 1840s onward. It was used to manage railway traffic and to prevent accidents as part of the railway signalling system. On 12 June 1837 Cooke and Wheatstone were awarded a patent for an electric telegraph. This was demonstrated between Euston railway station —where Wheatstone was located—and the engine house at Camden Town—where Cooke was stationed, together with Robert Stephenson ,
8613-638: Was invented by Claude Chappe and operated in France from 1793. The two most extensive systems were Chappe's in France, with branches into neighbouring countries, and the system of Abraham Niclas Edelcrantz in Sweden. During 1790–1795, at the height of the French Revolution , France needed a swift and reliable communication system to thwart the war efforts of its enemies. In 1790, the Chappe brothers set about devising
8712-522: Was invented by US Army surgeon Albert J. Myer in the 1850s who later became the first head of the Signal Corps . Wigwag was used extensively during the American Civil War where it filled a gap left by the electrical telegraph. Although the electrical telegraph had been in use for more than a decade, the network did not yet reach everywhere and portable, ruggedized equipment suitable for military use
8811-782: Was made in 1846, but it took a decade before it was fully taken out of service. The fall of Sevastopol was reported by Chappe telegraph in 1855. The Prussian system was put into effect in the 1830s. However, they were highly dependent on good weather and daylight to work and even then could accommodate only about two words per minute. The last commercial semaphore link ceased operation in Sweden in 1880. As of 1895, France still operated coastal commercial semaphore telegraph stations, for ship-to-shore communication. The early ideas for an electric telegraph included in 1753 using electrostatic deflections of pith balls, proposals for electrochemical bubbles in acid by Campillo in 1804 and von Sömmering in 1809. The first experimental system over
8910-400: Was not immediately available. Permanent or semi-permanent stations were established during the war, some of them towers of enormous height and the system was extensive enough to be described as a communications network. A heliograph is a telegraph that transmits messages by flashing sunlight with a mirror, usually using Morse code. The idea for a telegraph of this type was first proposed as
9009-478: Was one of the main contractors who served from 1982 to 1986 as MCI's Vice President of Digital Information Services. During his time in office, he acted as one of the driving forces behind the creation of the MCI Mail service. Cerf worked on the data networking related hardware and software applications of the MCI Mail. After an eight-year separation from the corporation to work with his Internet partner, Robert E. Kahn at
9108-455: Was preceded by a 50-year history of ingenious but ultimately unsuccessful experiments by inventors to achieve wireless telegraphy by other means. Several wireless electrical signaling schemes based on the (sometimes erroneous) idea that electric currents could be conducted long-range through water, ground, and air were investigated for telegraphy before practical radio systems became available. The original telegraph lines used two wires between
9207-433: Was proposed by Cooke in 1842. Railway signal telegraphy did not change in essence from Cooke's initial concept for more than a century. In this system each line of railway was divided into sections or blocks of varying length. Entry to and exit from the block was to be authorised by electric telegraph and signalled by the line-side semaphore signals, so that only a single train could occupy the rails. In Cooke's original system,
9306-496: Was quickly followed by a different system developed in the United States by Samuel Morse . The electric telegraph was slower to develop in France due to the established optical telegraph system, but an electrical telegraph was put into use with a code compatible with the Chappe optical telegraph. The Morse system was adopted as the international standard in 1865, using a modified Morse code developed in Germany in 1848. The heliograph
9405-542: Was rejected several times in favour of the more familiar, but shorter range, steam-powered pneumatic signalling. Even when his telegraph was taken up, it was considered experimental and the company backed out of a plan to finance extending the telegraph line out to Slough . However, this led to a breakthrough for the electric telegraph, as up to this point the Great Western had insisted on exclusive use and refused Cooke permission to open public telegraph offices. Cooke extended
9504-496: Was still 42.7 percent. During World War I , Britain's telegraph communications were almost completely uninterrupted while it was able to quickly cut Germany's cables worldwide. In 1843, Scottish inventor Alexander Bain invented a device that could be considered the first facsimile machine . He called his invention a "recording telegraph". Bain's telegraph was able to transmit images by electrical wires. Frederick Bakewell made several improvements on Bain's design and demonstrated
9603-404: Was still used, although it was accepted that poor weather ruled it out on many days of the year. France had an extensive optical telegraph system dating from Napoleonic times and was even slower to take up electrical systems. Eventually, electrostatic telegraphs were abandoned in favour of electromagnetic systems. An early experimental system ( Schilling , 1832) led to a proposal to establish
9702-603: Was the Chappe telegraph , an optical telegraph invented by Claude Chappe in the late 18th century. The system was used extensively in France, and European nations occupied by France, during the Napoleonic era . The electric telegraph started to replace the optical telegraph in the mid-19th century. It was first taken up in Britain in the form of the Cooke and Wheatstone telegraph , initially used mostly as an aid to railway signalling . This
9801-473: Was used by British military in many colonial wars, including the Anglo-Zulu War (1879). At some point, a morse key was added to the apparatus to give the operator the same degree of control as in the electric telegraph. Another type of heliograph was the heliostat or heliotrope fitted with a Colomb shutter. The heliostat was essentially a surveying instrument with a fixed mirror and so could not transmit
