27 Baudot, Jean-Maurice-Emile
[br]b. 11 September 1845 Magneux, Franced. 28 March 1903 Sceaux, France[br]French engineer who developed the multiplexed telegraph and devised a 5-bit code for data communication and control.[br]Baudot had no formal education beyond his local primary school and began his working life as a farmer, as was his father. However, in September 1869 he joined the French telegraph service and was soon sent on a course on the recently developed Hughes printing telegraph. After service in the Franco-Prussian war as a lieutenant with the military telegraph, he returned to his civilian duties in Paris in 1872. He was there encouraged to develop (in his own time!) a multiple Hughes system for time-multiplexing of several telegraph messages. By using synchronized clockwork-driven rotating switches at the transmitter and receiver he was able to transmit five messages simultaneously; the system was officially adopted by the French Post \& Telegraph Administration five years later. In 1874 he patented the idea of a 5-bit (i.e. 32-permutation) code, with equal on and off intervals, for telegraph transmission of the Roman alphabet and punctuation signs and for control of the typewriter-like teleprinter used to display the message. This code, known as the Baudot code, was found to be more economical than the existing Morse code and was widely adopted for national and international telegraphy in the twentieth century. In the 1970s it was superseded by 7—and 8-bit codes.Further development of his ideas on multiplexing led in 1894 to methods suitable for high-speed telegraphy. To commemorate his contribution to efficient telegraphy, the unit of signalling speed (i.e. the number of elements transmitted per second) is known as the baud.[br]Bibliography17 June 1874, "Système de télégraphie rapide" (Baudot's first patent).Further Reading1965, From Semaphore to Satellite, Geneva: International Telecommunications Union.P.Lajarrige, 1982, "Chroniques téléphoniques et télégraphiques", Collection historique des télécommunications.KFBiographical history of technology > Baudot, Jean-Maurice-Emile

28 Edison, Thomas Alva
SUBJECT AREA: Architecture and building, Automotive engineering, Electricity, Electronics and information technology, Metallurgy, Photography, film and optics, Public utilities, Recording, Telecommunications[br]b. 11 February 1847 Milan, Ohio, USAd. 18 October 1931 Glenmont[br]American inventor and pioneer electrical developer.[br]He was the son of Samuel Edison, who was in the timber business. His schooling was delayed due to scarlet fever until 1855, when he was 8½ years old, but he was an avid reader. By the age of 14 he had a job as a newsboy on the railway from Port Huron to Detroit, a distance of sixty-three miles (101 km). He worked a fourteen-hour day with a stopover of five hours, which he spent in the Detroit Free Library. He also sold sweets on the train and, later, fruit and vegetables, and was soon making a profit of $20 a week. He then started two stores in Port Huron and used a spare freight car as a laboratory. He added a hand-printing press to produce 400 copies weekly of The Grand Trunk Herald, most of which he compiled and edited himself. He set himself to learn telegraphy from the station agent at Mount Clements, whose son he had saved from being run over by a freight car.At the age of 16 he became a telegraphist at Port Huron. In 1863 he became railway telegraphist at the busy Stratford Junction of the Grand Trunk Railroad, arranging a clock with a notched wheel to give the hourly signal which was to prove that he was awake and at his post! He left hurriedly after failing to hold a train which was nearly involved in a head-on collision. He usually worked the night shift, allowing himself time for experiments during the day. His first invention was an arrangement of two Morse registers so that a high-speed input could be decoded at a slower speed. Moving from place to place he held many positions as a telegraphist. In Boston he invented an automatic vote recorder for Congress and patented it, but the idea was rejected. This was the first of a total of 1180 patents that he was to take out during his lifetime. After six years he resigned from the Western Union Company to devote all his time to invention, his next idea being an improved ticker-tape machine for stockbrokers. He developed a duplex telegraphy system, but this was turned down by the Western Union Company. He then moved to New York.Edison found accommodation in the battery room of Law's Gold Reporting Company, sleeping in the cellar, and there his repair of a broken transmitter marked him as someone of special talents. His superior soon resigned, and he was promoted with a salary of $300 a month. Western Union paid him $40,000 for the sole rights on future improvements on the duplex telegraph, and he moved to Ward Street, Newark, New Jersey, where he employed a gathering of specialist engineers. Within a year, he married one of his employees, Mary Stilwell, when she was only 16: a daughter, Marion, was born in 1872, and two sons, Thomas and William, in 1876 and 1879, respectively.He continued to work on the automatic telegraph, a device to send out messages faster than they could be tapped out by hand: that is, over fifty words per minute or so. An earlier machine by Alexander Bain worked at up to 400 words per minute, but was not good over long distances. Edison agreed to work on improving this feature of Bain's machine for the Automatic Telegraph Company (ATC) for $40,000. He improved it to a working speed of 500 words per minute and ran a test between Washington and New York. Hoping to sell their equipment to the Post Office in Britain, ATC sent Edison to England in 1873 to negotiate. A 500-word message was to be sent from Liverpool to London every half-hour for six hours, followed by tests on 2,200 miles (3,540 km) of cable at Greenwich. Only confused results were obtained due to induction in the cable, which lay coiled in a water tank. Edison returned to New York, where he worked on his quadruplex telegraph system, tests of which proved a success between New York and Albany in December 1874. Unfortunately, simultaneous negotiation with Western Union and ATC resulted in a lawsuit.Alexander Graham Bell was granted a patent for a telephone in March 1876 while Edison was still working on the same idea. His improvements allowed the device to operate over a distance of hundreds of miles instead of only a few miles. Tests were carried out over the 106 miles (170 km) between New York and Philadelphia. Edison applied for a patent on the carbon-button transmitter in April 1877, Western Union agreeing to pay him $6,000 a year for the seventeen-year duration of the patent. In these years he was also working on the development of the electric lamp and on a duplicating machine which would make up to 3,000 copies from a stencil. In 1876–7 he moved from Newark to Menlo Park, twenty-four miles (39 km) from New York on the Pennsylvania Railway, near Elizabeth. He had bought a house there around which he built the premises that would become his "inventions factory". It was there that he began the use of his 200- page pocket notebooks, each of which lasted him about two weeks, so prolific were his ideas. When he died he left 3,400 of them filled with notes and sketches.Late in 1877 he applied for a patent for a phonograph which was granted on 19 February 1878, and by the end of the year he had formed a company to manufacture this totally new product. At the time, Edison saw the device primarily as a business aid rather than for entertainment, rather as a dictating machine. In August 1878 he was granted a British patent. In July 1878 he tried to measure the heat from the solar corona at a solar eclipse viewed from Rawlins, Wyoming, but his "tasimeter" was too sensitive.Probably his greatest achievement was "The Subdivision of the Electric Light" or the "glow bulb". He tried many materials for the filament before settling on carbon. He gave a demonstration of electric light by lighting up Menlo Park and inviting the public. Edison was, of course, faced with the problem of inventing and producing all the ancillaries which go to make up the electrical system of generation and distribution-meters, fuses, insulation, switches, cabling—even generators had to be designed and built; everything was new. He started a number of manufacturing companies to produce the various components needed.In 1881 he built the world's largest generator, which weighed 27 tons, to light 1,200 lamps at the Paris Exhibition. It was later moved to England to be used in the world's first central power station with steam engine drive at Holborn Viaduct, London. In September 1882 he started up his Pearl Street Generating Station in New York, which led to a worldwide increase in the application of electric power, particularly for lighting. At the same time as these developments, he built a 1,300yd (1,190m) electric railway at Menlo Park.On 9 August 1884 his wife died of typhoid. Using his telegraphic skills, he proposed to 19-year-old Mina Miller in Morse code while in the company of others on a train. He married her in February 1885 before buying a new house and estate at West Orange, New Jersey, building a new laboratory not far away in the Orange Valley.Edison used direct current which was limited to around 250 volts. Alternating current was largely developed by George Westinghouse and Nicola Tesla, using transformers to step up the current to a higher voltage for long-distance transmission. The use of AC gradually overtook the Edison DC system.In autumn 1888 he patented a form of cinephotography, the kinetoscope, obtaining film-stock from George Eastman. In 1893 he set up the first film studio, which was pivoted so as to catch the sun, with a hinged roof which could be raised. In 1894 kinetoscope parlours with "peep shows" were starting up in cities all over America. Competition came from the Latham Brothers with a screen-projection machine, which Edison answered with his "Vitascope", shown in New York in 1896. This showed pictures with accompanying sound, but there was some difficulty with synchronization. Edison also experimented with captions at this early date.In 1880 he filed a patent for a magnetic ore separator, the first of nearly sixty. He bought up deposits of low-grade iron ore which had been developed in the north of New Jersey. The process was a commercial success until the discovery of iron-rich ore in Minnesota rendered it uneconomic and uncompetitive. In 1898 cement rock was discovered in New Village, west of West Orange. Edison bought the land and started cement manufacture, using kilns twice the normal length and using half as much fuel to heat them as the normal type of kiln. In 1893 he met Henry Ford, who was building his second car, at an Edison convention. This started him on the development of a battery for an electric car on which he made over 9,000 experiments. In 1903 he sold his patent for wireless telegraphy "for a song" to Guglielmo Marconi.In 1910 Edison designed a prefabricated concrete house. In December 1914 fire destroyed three-quarters of the West Orange plant, but it was at once rebuilt, and with the threat of war Edison started to set up his own plants for making all the chemicals that he had previously been buying from Europe, such as carbolic acid, phenol, benzol, aniline dyes, etc. He was appointed President of the Navy Consulting Board, for whom, he said, he made some forty-five inventions, "but they were pigeonholed, every one of them". Thus did Edison find that the Navy did not take kindly to civilian interference.In 1927 he started the Edison Botanic Research Company, founded with similar investment from Ford and Firestone with the object of finding a substitute for overseas-produced rubber. In the first year he tested no fewer than 3,327 possible plants, in the second year, over 1,400, eventually developing a variety of Golden Rod which grew to 14 ft (4.3 m) in height. However, all this effort and money was wasted, due to the discovery of synthetic rubber.In October 1929 he was present at Henry Ford's opening of his Dearborn Museum to celebrate the fiftieth anniversary of the incandescent lamp, including a replica of the Menlo Park laboratory. He was awarded the Congressional Gold Medal and was elected to the American Academy of Sciences. He died in 1931 at his home, Glenmont; throughout the USA, lights were dimmed temporarily on the day of his funeral.[br]Principal Honours and DistinctionsMember of the American Academy of Sciences.

30 Wheatstone, Sir Charles
SUBJECT AREA: Telecommunications[br]b. 1802 near Gloucester, Englandd. 19 October 1875 Paris, France[br]English physicist, pioneer of electric telegraphy.[br]Wheatstone's family moved to London when he was 4 years old. He was educated at various schools in London and excelled in physics and mathematics. He qualified for a French prize but forfeited it because he was too shy to recite a speech in French at the prize-giving.An uncle, also called Charles Wheatstone, has a musical instrument manufacturing business where young Charles went to work. He was fascinated by the science of music, but did not enjoy business life. After the uncle's death, Charles and his brother William took over the business. Charles developed and patented the concertina, which the firm assembled from parts made by "outworkers". He devoted much of his time to studying the physics of sound and mechanism of sound transmission through solids. He sent speech and music over considerable distances through solid rods and stretched wires, and envisaged communication at a distance. He concluded, however, that electrical methods were more promising.In 1834 Wheatstone was appointed Professor of Experimental Philosophy—a part-time posi-tion—in the new King's College, London, which gave him some research facilities. He conducted experiments with a telegraph system using several miles of wire in the college corridors. Jointly with William Fothergill Cooke, in 1837 he obtained the first patent for a practical electric telegraph, and much of the remainder of his life was devoted to its improvement. In 1843 he gave a paper to the Royal Society surveying the state of electrical measurements and drew attention to a bridge circuit known ever since as the "Wheatstone bridge", although he clearly attributed it to S.H.Christie. Wheatstone devised the "ABC" telegraph, for use on private lines by anyone who could read, and a high-speed automatic telegraph which was adopted by the Post Office and used for many years. He also worked on the French and Belgian telegraph systems; he died when taken ill on a business visit to Paris.[br]Further ReadingB.Bowers, 1975, Sir Charles Wheatstone FRS, London: HMSO.BBBiographical history of technology > Wheatstone, Sir Charles

37 Chappe, Claude
SUBJECT AREA: Telecommunications[br]b. 25 December 1763 Brulon, Franced. 23 January 1805 Paris, France[br]French engineer who invented the semaphore visual telegraph.[br]Chappe began his studies at the Collège de Joyeuse, Rouen, and completed them at La Flèche. He was educated for the church with the intention of becoming an Abbé Commendataire, but this title did not in fact require him to perform any religious duties. He became interested in natural science and amongst other activities he carried out experiments with electrically charged soap bubbles.When the bénéfice was suppressed in 1781 he returned home and began to devise a system of telegraphic communication. With the help of his three brothers, particularly Abraham, and using an old idea, in 1790 he made a visual telegraph with suspended pendulums to relay coded messages over a distance of half a kilometre. Despite public suspicion and opposition, he presented the idea to the Assemblée Nationale on 22 May 1792. No doubt due to the influence of his brother, Ignace, a member of the Assemblée Nationale, the idea was favourably received, and on 1 April 1793 it was referred to the National Convention as being of military importance. As a result, Chappe was given the title of Telegraphy Engineer and commissioned to construct a semaphore (Gk. bearing a sign) link between Paris and Lille, a distance of some 240 km (150 miles), using twenty-two towers. Each station contained two telescopes for observing the adjacent towers, and each semaphore consisted of a central beam supporting two arms, whose positions gave nearly two hundred possible arrangements. Hence, by using a code book as a form of lookup table, Chappe was able to devise a code of over 8,000 words. The success of the system for communication during subsequent military conflicts resulted in him being commissioned to extend it with further links, a work that was continued by his brothers after his suicide during a period of illness and depression. Providing as it did an effective message speed of several thousand kilometres per hour, the system remained in use until the mid-nineteenth century, by which time the electric telegraph had become well established.[br]Further ReadingR.Appleyard, 1930, Pioneers of Electrical Communication.International Telecommunications Union, 1965, From Semaphore to Satellite, Geneva.See also: Morse, Samuel Finley BreezeKF -
38 Nyquist, Harry
[br]b. 7 February 1889 Nilsby, Swedend. 4 April 1976 Texas, USA[br]Swedish-American engineer who established the formula for thermal noise in electrical circuits and the stability criterion for feedback amplifiers.[br]Nyquist (original family name Nykvist) emigrated from Sweden to the USA when he was 18 years old and settled in Minnesota. After teaching for a time, he studied electrical engineering at the University of North Dakota, gaining his first and Master's degrees in 1915 and 1916, and his PhD from Yale in 1917. He then joined the American Telegraph \& Telephone Company, moving to its Bell Laboratories in 1934 and remaining there until his retirement in 1954. A prolific inventor, he made many contributions to communication engineering, including the invention of vestigial-side band transmission. In the late 1920s he analysed the behaviour of analogue and digital signals in communication circuits, and in 1928 he showed that the thermal noise per unit bandwidth is given by 4 kT, where k is Boltzmann's constant and T the absolute temperature. However, he is best known for the Nyquist Criterion, which defines the conditions necessary for the stable, oscillation-free operation of amplifiers with a closed feedback loop. The problem of how to realize these conditions was investigated by his colleague Hendrik Bode.[br]Principal Honours and DistinctionsFranklin Institute Medal 1960.
