11 Kompfner, Rudolph
[br]b. 16 May 1909 Vienna, Austriad. 3 December 1977 Stanford, California, USA[br]Austrian (naturalized English in 1949, American in 1957) electrical engineer primarily known for his invention of the travelling-wave tube.[br]Kompfner obtained a degree in engineering from the Vienna Technische Hochschule in 1931 and qualified as a Diplom-Ingenieur in Architecture two years later. The following year, with a worsening political situation in Austria, he moved to England and became an architectural apprentice. In 1936 he became Managing Director of a building firm owned by a relative, but at the same time he was avidly studying physics and electronics. His first patent, for a television pick-up device, was filed in 1935 and granted in 1937, but was not in fact taken up. In June 1940 he was interned on the Isle of Man, but as a result of a paper previously sent by him to the Editor of Wireless Engineer he was released the following December and sent to join the group at Birmingham University working on centimetric radar. There he worked on klystrons, with little success, but as a result of the experience gained he eventually invented the travelling-wave tube (TWT), which was based on a helical transmission line. After disbandment of the Birmingham team, in 1946 Kompfner moved to the Clarendon Laboratory at Oxford and in 1947 he became a British subject. At the Clarendon Laboratory he met J.R. Pierce of Bell Laboratories, who worked out the theory of operation of the TWT. After gaining his DPhil at Oxford in 1951, Kompfner accepted a post as Principal Scientific Officer at Signals Electronic Research Laboratories, Baldock, but very soon after that he was invited by Pierce to work at Bell on microwave tubes. There, in 1952, he invented the backward-wave oscillator (BWO). He was appointed Director of Electronics Research in 1955 and Director of Communications Research in 1962, having become a US citizen in 1957. In 1958, with Pierce, he designed Echo 1, the first (passive) satellite, which was launched in August 1960. He was also involved with the development of Telstar, the first active communications satellite, which was launched in 1962. Following his retirement from Bell in 1973, he continued to pursue research, alternately at Stanford, California, and Oxford, England.[br]Principal Honours and DistinctionsPhysical Society Duddell Medal 1955.

12 Preece, Sir William Henry
[br]b. 15 February 1834 Bryn Helen, Gwynedd, Walesd. 6 November 1913 Penrhos, Gwynedd, Wales[br]Welsh electrical engineer who greatly furthered the development and use of wireless telegraphy and the telephone in Britain, dominating British Post Office engineering during the last two decades of the nineteenth century.[br]After education at King's College, London, in 1852 Preece entered the office of Edwin Clark with the intention of becoming a civil engineer, but graduate studies at the Royal Institution under Faraday fired his enthusiasm for things electrical. His earliest work, as connected with telegraphy and in particular its application for securing the safe working of railways; in 1853 he obtained an appointment with the Electric and National Telegraph Company. In 1856 he became Superintendent of that company's southern district, but four years later he moved to telegraph work with the London and South West Railway. From 1858 to 1862 he was also Engineer to the Channel Islands Telegraph Company. When the various telegraph companies in Britain were transferred to the State in 1870, Preece became a Divisional Engineer in the General Post Office (GPO). Promotion followed in 1877, when he was appointed Chief Electrician to the Post Office. One of the first specimens of Bell's telephone was brought to England by Preece and exhibited at the British Association meeting in 1877. From 1892 to 1899 he served as Engineer-in-Chief to the Post Office. During this time he made a number of important contributions to telegraphy, including the use of water as part of telegraph circuits across the Solent (1882) and the Bristol Channel (1888). He also discovered the existence of inductive effects between parallel wires, and with Fleming showed that a current (thermionic) flowed between the hot filament and a cold conductor in an incandescent lamp.Preece was distinguished by his administrative ability, some scientific insight, considerable engineering intuition and immense energy. He held erroneous views about telephone transmission and, not accepting the work of Oliver Heaviside, made many errors when planning trunk circuits. Prior to the successful use of Hertzian waves for wireless communication Preece carried out experiments, often on a large scale, in attempts at wireless communication by inductive methods. These became of historic interest only when the work of Maxwell and Hertz was developed by Guglielmo Marconi. It is to Preece that credit should be given for encouraging Marconi in 1896 and collaborating with him in his early experimental work on radio telegraphy.While still employed by the Post Office, Preece contributed to the development of numerous early public electricity schemes, acting as Consultant and often supervising their construction. At Worcester he was responsible for Britain's largest nineteenth-century public hydro-electric station. He received a knighthood on his retirement in 1899, after which he continued his consulting practice in association with his two sons and Major Philip Cardew. Preece contributed some 136 papers and printed lectures to scientific journals, ninety-nine during the period 1877 to 1894.[br]Principal Honours and DistinctionsCB 1894. Knighted (KCB) 1899.

13 Bright, Sir Charles Tilston
SUBJECT AREA: Telecommunications[br]b. 8 June 1832 Wanstead, Essex, Englandd. 3 May 1888 Abbey Wood, London, England[br]English telegraph engineer responsible for laying the first transatlantic cable.[br]At the age of 15 years Bright left the London Merchant Taylors' School to join the two-year-old Electric Telegraph Company. By 1851 he was in charge of the Birmingham telegraph station. After a short time as Assistant Engineer with the newly formed British Telegraph Company, he joined his brother (who was Manager) as Engineer-in-Chief of the English and Irish Magnetic Telegraph Company in Liverpool, for which he laid thousands of miles of underground cable and developed a number of innovations in telegraphy including a resistance box for locating cable faults and a two-tone bell system for signalling. In 1853 he was responsible for the first successful underwater cable between Scotland and Ireland. Three years later, with the American financier Cyrus Field and John Brett, he founded and was Engineer-in-chief of the Atlantic Telegraph Company, which aimed at laying a cable between Ireland and Newfoundland. After several unsuccessful attempts this was finally completed on 5 August 1858, Bright was knighted a month later, but the cable then failed! In 1860 Bright resigned from the Magnetic Telegraph Company to set up an independent consultancy with another engineer, Joseph Latimer Clark, with whom he invented an improved bituminous cable insulation. Two years later he supervised construction of a telegraph cable to India, and in 1865 a further attempt to lay an Atlantic cable using Brunel's new ship, the Great Eastern. This cable broke during laying, but in 1866 a new cable was at last successfully laid and the 1865 cable recovered and repaired. The year 1878 saw extension of the Atlantic cable system to the West Indies and the invention with his brother of a system of neighbourhood fire alarms and even an automatic fire alarm.In 1861 Bright presented a paper to the British Association for the Advancement of Science on the need for electrical standards, leading to the creation of an organization that still exists in the 1990s. From 1865 until 1868 he was Liberal MP for Greenwich, and he later assisted with preparations for the 1881 Paris Exhibition.[br]Principal Honours and DistinctionsKnighted 1858. Légion d'honneur.

15 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 -
16 Hetzel, Max
[br]b. 5 March 1921 Basle, Switzerland[br]Swiss electrical engineer who invented the tuning-fork watch.[br]Hetzel trained as an electrical engineer at the Federal Polytechnic in Zurich and worked for several years in the field of telecommunications before joining the Bulova Watch Company in 1950. At that time several companies were developing watches with electromagnetically maintained balances, but they represented very little advance on the mechanical watch and the mechanical switching mechanism was unreliable. In 1952 Hetzel started work on a much more radical design which was influenced by a transistorized tuning-fork oscillator that he had developed when he was working on telecommunications. Tuning forks, whose vibrations were maintained electromagnetically, had been used by scientists during the nineteenth century to measure small intervals of time, but Niaudet- Breguet appears to have been the first to use a tuning fork to control a clock. In 1866 he described a mechanically operated tuning-fork clock manufactured by the firm of Breguet, but it was not successful, possibly because the fork did not compensate for changes in temperature. The tuning fork only became a precision instrument during the 1920s, when elinvar forks were maintained in vibration by thermionic valve circuits. Their primary purpose was to act as frequency standards, but they might have been developed into precision clocks had not the quartz clock made its appearance very shortly afterwards. Hetzel's design was effectively a miniaturized version of these precision devices, with a transistor replacing the thermionic valve. The fork vibrated at a frequency of 360 cycles per second, and the hands were driven mechanically from the end of one of the tines. A prototype was working by 1954, and the watch went into production in 1960. It was sold under the tradename Accutron, with a guaranteed accuracy of one minute per month: this was a considerable improvement on the performance of the mechanical watch. However, the events of the 1920s were to repeat themselves, and by the end of the decade the Accutron was eclipsed by the introduction of quartz-crystal watches.[br]Principal Honours and DistinctionsNeuchâtel Observatory Centenary Prize 1958.

18 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

19 Williams, Sir Frederic Calland
SUBJECT AREA: Electronics and information technology[br]b. 26 June 1911 Stockport, Cheshire, Englandd. 11 August 1977 Prestbury, Cheshire, England[br]English electrical engineer who invented the Williams storage cathode ray tube, which was extensively used worldwide as a data memory in the first digital computers.[br]Following education at Stockport Grammar School, Williams entered Manchester University in 1929, gaining his BSc in 1932 and MSc in 1933. After a short time as a college apprentice with Metropolitan Vickers, he went to Magdalen College, Oxford, to study for a DPhil, which he was awarded in 1936. He returned to Manchester University that year as an assistant lecturer, gaining his DSc in 1939. Following the outbreak of the Second World War he worked for the Scientific Civil Service, initially at the Bawdsey Research Station and then at the Telecommunications Research Establishment at Malvern, Worcestershire. There he was involved in research on non-incandescent amplifiers and diode rectifiers and the development of the first practical radar system capable of identifying friendly aircraft. Later in the war, he devised an automatic radar system suitable for use by fighter aircraft.After the war he resumed his academic career at Manchester, becoming Professor of Electrical Engineering and Director of the University Electrotechnical Laboratory in 1946. In the same year he succeeded in developing a data-memory device based on the cathode ray tube, in which the information was stored and read by electron-beam scanning of a charge-retaining target. The Williams storage tube, as it became known, not only found obvious later use as a means of storing single-frame, still television images but proved to be a vital component of the pioneering Manchester University MkI digital computer. Because it enabled both data and program instructions to be stored in the computer, it was soon used worldwide in the development of the early stored-program computers.[br]Principal Honours and DistinctionsKnighted 1976.
