16 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.

17 Paul, Robert William
[br]b. 3 October 1869 Highbury, London, Englandd. 28 March 1943 London, England[br]English scientific instrument maker, inventor of the Unipivot electrical measuring instrument, and pioneer of cinematography.[br]Paul was educated at the City of London School and Finsbury Technical College. He worked first for a short time in the Bell Telephone Works in Antwerp, Belgium, and then in the electrical instrument shop of Elliott Brothers in the Strand until 1891, when he opened an instrument-making business at 44 Hatton Garden, London. He specialized in the design and manufacture of electrical instruments, including the Ayrton Mather galvanometer. In 1902, with a purpose-built factory, he began large batch production of his instruments. He also opened a factory in New York, where uncalibrated instruments from England were calibrated for American customers. In 1903 Paul introduced the Unipivot galvanometer, in which the coil was supported at the centre of gravity of the moving system on a single pivot. The pivotal friction was less than in a conventional instrument and could be used without accurate levelling, the sensitivity being far beyond that of any pivoted galvanometer then in existence.In 1894 Paul was asked by two entrepreneurs to make copies of Edison's kinetoscope, the pioneering peep-show moving-picture viewer, which had just arrived in London. Discovering that Edison had omitted to patent the machine in England, and observing that there was considerable demand for the machine from show-people, he began production, making six before the end of the year. Altogether, he made about sixty-six units, some of which were exported. Although Edison's machine was not patented, his films were certainly copyrighted, so Paul now needed a cinematographic camera to make new subjects for his customers. Early in 1895 he came into contact with Birt Acres, who was also working on the design of a movie camera. Acres's design was somewhat impractical, but Paul constructed a working model with which Acres filmed the Oxford and Cambridge Boat Race on 30 March, and the Derby at Epsom on 29 May. Paul was unhappy with the inefficient design, and developed a new intermittent mechanism based on the principle of the Maltese cross. Despite having signed a ten-year agreement with Paul, Acres split with him on 12 July 1895, after having unilaterally patented their original camera design on 27 May. By the early weeks of 1896, Paul had developed a projector mechanism that also used the Maltese cross and which he demonstrated at the Finsbury Technical College on 20 February 1896. His Theatrograph was intended for sale, and was shown in a number of venues in London during March, notably at the Alhambra Theatre in Leicester Square. There the renamed Animatographe was used to show, among other subjects, the Derby of 1896, which was won by the Prince of Wales's horse "Persimmon" and the film of which was shown the next day to enthusiastic crowds. The production of films turned out to be quite profitable: in the first year of the business, from March 1896, Paul made a net profit of £12,838 on a capital outlay of about £1,000. By the end of the year there were at least five shows running in London that were using Paul's projectors and screening films made by him or his staff.Paul played a major part in establishing the film business in England through his readiness to sell apparatus at a time when most of his rivals reserved their equipment for sole exploitation. He went on to become a leading producer of films, specializing in trick effects, many of which he pioneered. He was affectionately known in the trade as "Daddy Paul", truly considered to be the "father" of the British film industry. He continued to appreciate fully the possibilities of cinematography for scientific work, and in collaboration with Professor Silvanus P.Thompson films were made to illustrate various phenomena to students.Paul ended his involvement with film making in 1910 to concentrate on his instrument business; on his retirement in 1920, this was amalgamated with the Cambridge Instrument Company. In his will he left shares valued at over £100,000 to form the R.W.Paul Instrument Fund, to be administered by the Institution of Electrical Engineers, of which he had been a member since 1887. The fund was to provide instruments of an unusual nature to assist physical research.[br]Principal Honours and DistinctionsFellow of the Physical Society 1920.

18 Reis, (Johann) Philipp
SUBJECT AREA: Telecommunications[br]b. 7 January 1834 Geinherusen, Hesse-Kassel, Germanyd. 14 January 1874 Friedrichsdorf, Germany[br]German schoolteacher and inventor who constructed an early form of telephone.[br]Reis entered the Garniers Institute in Friedrichsdorf in 1844 and then the Hassels Institute in Frankfurt. There he developed an interest in science, but on leaving school in 1850 he was apprenticed to the colour trade by his uncle. This involved study at the trade school and Dr Poppe's Institute in Frankfurt; while there he joined the Frankfurt Physical Society. Following military service in 1855 he studied to be a teacher. After his graduation he obtained a post at Garniers, where he began to pursue experiments with electricity and the development of hearing aids. In 1859 he sent a paper on the radiation of electricity to the editor of Annalen der Physik, but this was rejected, as was a later submission. Undeterred, he continued his experiments and by 1861 he had designed several instruments for the transmission of sound. The transmitter consisted of a membrane on which rested a metal strip that made contact with a metal point and completed an electrical circuit under the action of sound. The receiver consisted of an iron needle surrounded by a coil and resting on a sounding box, the operation probably being achieved by magnetostriction. The invention, which he described in a lecture to the Frankfurt Physical Society on 26 October 1861 and in a published paper, could produce tones and probably also speech, but was largely rejected by the scientific fraternity. The claim to produce speech was discounted in subsequent court cases that upheld the patents of Alexander Bell.[br]Principal Honours and DistinctionsOn 8 December 1878 a monument to Reis was erected in the Friedrichsdorf Cemetery by the Physical Society of Frankfurt.Bibliography1860–1, "Über Telephone durch den galvani-schen Strom", Jahresbericht der Physikalische 57.Further ReadingJ.Munro, 1891, Heroes of the Telegraph.Silvanus P.Thompson, 1883, Philipp Reis.

19 Thomson, Sir William, Lord Kelvin
[br]b. 26 June 1824 Belfast, Ireland (now Northern Ireland)d. 17 December 1907 Largs, Scotland[br]Irish physicist and inventor who contributed to submarine telegraphy and instrumentation.[br]After education at Glasgow University and Peterhouse, Cambridge, a period of study in France gave Thomson an interest in experimental work and instrumentation. He became Professor of Natural Philosophy at Glasgow in 1846 and retained the position for the rest of his career, establishing the first teaching laboratory in Britain.Among his many contributions to science and engineering was his concept, introduced in 1848, of an "absolute" zero of temperature. Following on from the work of Joule, his investigations into the nature of heat led to the first successful liquefaction of gases such as hydrogen and helium, and later to the science of low-temperature physics.Cable telegraphy gave an impetus to the scientific measurement of electrical quantities, and for many years Thomson was a member of the British Association Committee formed in 1861 to consider electrical standards and to develop units; these are still in use. Thomson first became Scientific Adviser to the Atlantic Telegraph Company in 1857, sailing on the Agamemnon and Great Eastern during the cable-laying expeditions. He invented a mirror galvanometer and more importantly the siphon recorder, which, used as a very sensitive telegraph receiver, provided a permanent record of signals. He also laid down the design parameters of long submarine cables and discovered that the conductivity of copper was greatly affected by its purity. A major part of the success of the Atlantic cable in 1866 was due to Thomson, who received a knighthood for his contribution.Other instruments he designed included a quadrant electrostatic voltmeter to measure high voltages, and his "multi-cellular" instrument for low voltages. They could be used on alternating or direct current and were free from temperature errors. His balances for precision current measurement were widely used in standardizing laboratories.Thomson was a prolific writer of scientific papers on subjects across the whole spectrum of physics; between 1855 and 1866 he published some 110 papers, with a total during his life of over 600. In 1892 he was raised to the peerage as Baron Kelvin of Largs. By the time of his death he was looked upon as the "father" of British physics, but despite his outstanding achievements his later years were spent resisting change and progress.[br]Principal Honours and DistinctionsKnighted 1866.
