41 Poulsen, Valdemar
[br]b. 23 November 1869 Copenhagen, Denmarkd. 23 July 1942 Gentofte, Denmark[br]Danish engineer who developed practical magnetic recording and the arc generator for continuous radio waves.[br]From an early age he was absorbed by phenomena of physics to the exclusion of all other subjects, including mathematics. When choosing his subjects for the final three years in Borgedydskolen in Christianshavn (Copenhagen) before university, he opted for languages and history. At the University of Copenhagen he embarked on the study of medicine in 1889, but broke it off and was apprenticed to the machine firm of A/S Frichs Eftf. in Aarhus. He was employed between 1893 and 1899 as a mechanic and assistant in the laboratory of the Copenhagen Telephone Company KTAS. Eventually he advanced to be Head of the line fault department. This suited his desire for experiment and measurement perfectly. After the invention of the telegraphone in 1898, he left the laboratory and with responsible business people he created Aktieselskabet Telegrafonen, Patent Poulsen in order to develop it further, together with Peder Oluf Pedersen (1874– 1941). Pedersen brought with him the mathematical background which eventually led to his professorship in electronic engineering in 1922.The telegraphone was the basis for multinational industrial endeavours after it was demonstrated at the 1900 World's Exhibition in Paris. It must be said that its strength was also its weakness, because the telegraphone was unique in bringing sound recording and reproduction to the telephone field, but the lack of electronic amplifiers delayed its use outside this and the dictation fields (where headphones could be used) until the 1920s. However, commercial interest was great enough to provoke a number of court cases concerning patent infringement, in which Poulsen frequently figured as a witness.In 1903–4 Poulsen and Pedersen developed the arc generator for continuous radio waves which was used worldwide for radio transmitters in competition with Marconi's spark-generating system. The inspiration for this work came from the research by William Duddell on the musical arc. Whereas Duddell had proposed the use of the oscillations generated in his electric arc for telegraphy in his 1901 UK patent, Poulsen contributed a chamber of hydrogen and a transverse magnetic field which increased the efficiency remarkably. He filed patent applications on these constructions from 1902 and the first publication in a scientific forum took place at the International Electrical Congress in St Louis, Missouri, in 1904.In order to use continuous waves efficiently (the high frequency constituted a carrier), Poulsen developed both a modulator for telegraphy and a detector for the carrier wave. The modulator was such that even the more primitive spark-communication receivers could be used. Later Poulsen and Pedersen developed frequency-shift keying.The Amalgamated Radio-Telegraph Company Ltd was launched in London in 1906, combining the developments of Poulsen and those of De Forest Wireless Telegraph Syndicate. Poulsen contributed his English and American patents. When this company was liquidated in 1908, its assets were taken over by Det Kontinentale Syndikat for Poulsen Radio Telegrafi, A/S in Copenhagen (liquidated 1930–1). Some of the patents had been sold to C.Lorenz AG in Berlin, which was very active.The arc transmitting system was in use worldwide from about 1910 to 1925, and the power increased from 12 kW to 1,000 kW. In 1921 an exceptional transmitter rated at 1,800 kW was erected on Java for communications with the Netherlands. More than one thousand installations had been in use worldwide. The competing systems were initially spark transmitters (Marconi) and later rotary converters ( Westinghouse). Similar power was available from valve transmitters only much later.From c. 1912 Poulsen did not contribute actively to further development. He led a life as a well-respected engineer and scientist and served on several committees. He had his private laboratory and made experiments in the composition of matter and certain resonance phenomena; however, nothing was published. It has recently been suggested that Poulsen could not have been unaware of Oberlin Smith's work and publication in 1888, but his extreme honesty in technical matters indicates that his development was indeed independent. In the case of the arc generator, Poulsen was always extremely frank about the inspiration he gained from earlier developers' work.[br]Bibliography1899, British patent no. 8,961 (the first British telegraphone patent). 1903, British patent no. 15,599 (the first British arc-genera tor patent).His scientific publications are few, but fundamental accounts of his contribution are: 1900, "Das Telegraphon", Ann. d. Physik 3:754–60; 1904, "System for producing continuous oscillations", Trans. Int. El. Congr. St. Louis, Vol. II, pp. 963–71.Further ReadingA.Larsen, 1950, Telegrafonen og den Traadløse, Ingeniørvidenskabelige Skrifter no. 2, Copenhagen (provides a very complete, although somewhat confusing, account of Poulsen's contributions; a list of his patents is given on pp. 285–93).F.K.Engel, 1990, Documents on the Invention of Magnetic Re cor ding in 1878, New York: Audio Engineering Society, reprint no. 2,914 (G2) (it is here that doubt is expressed about whether Poulsen's ideas were developed independently).GB-N -
42 Kennelly, Arthur Edwin
[br]b. 17 December 1871 Colaba, Bombay, Indiad. 18 June 1939 Boston, Massachusetts, USA[br]Anglo-American electrical engineer who predicted the ionosphere and developed mathematical analysis for electronic circuits.[br]As a young man, Kennelly worked as office boy for a London engineering society, as an electrician and on a cable-laying ship. In 1887 he went to work for Thomas Edison at West Orange, New Jersey, USA, becoming his chief assistant. In 1894, with Edwin J.Houston, he formed the Philadelphia company of Houston and Kennelly, but eight years later he took up the Chair of Electrical Engineering at Harvard, a post he held until his retirement in 1930. In 1902 he noticed that the radio signals received by Marconi in Nova Scotia from the transmitter in England were stronger than predicted and postulated a reflecting ionized layer in the upper atmosphere. Almost simultaneously the same prediction was made in England by Heaviside, so the layer became known as the Kennelly-Heaviside layer. Throughout most of his working life Kennelly was concerned with the application of mathematical techniques, particularly the use of complex theory, to the analysis of electrical circuits. With others he also contributed to an understanding of the high-frequency skin-effect in conductors.[br]Principal Honours and DistinctionsPresident, American Institute of Electrical Engineers 1898–1900.

44 Hartley, Ralph V.L.
[br]b. 1889 USAd. 1 May 1970 Summit, New Jersey, USA[br]American engineer who made contributions to radio communications.[br]Hartley obtained his BA in 1909 from the University of Utah, then gained a Rhodes Scholarship to Oxford University, England. After obtaining a further BA and a BSc in 1912 and 1913, respectively, he returned to the USA and took a job with the Western Electric Laboratories of the Bell Telephone Company, where he was in charge of radio-receiver development. In 1915 he invented the Hartley oscillator, analogous to that invented by Colpitts. Subsequently he worked on carrier telephony at Western Electric and then at Bell Laboratories. There he concen-trated on information theory, building on the pioneering work of Nyquist, in 1926 publishing his law that related information capacity, frequency bandwidth and time. Forced to give up work in 1929 due to ill health, he returned to Bell in 1939 as a consultant on transmission problems. During the Second World War he worked on various projects, including the use of servo-mechanisms for radar and fire control, and finally retired in 1950.[br]Principal Honours and DistinctionsInstitution of Electrical and Electronics Enginners Medal of Honour 1946.Bibliography29 May 1918, US patent no. 1,592,934 (plate modulator).29 September 1919, US patent no. 1,419,562 (balanced modulator or detector). 1922, with T.C.Fry, "Binaural location of complex sounds", Bell Systems TechnicalJournal (November).1923, "Relation of carrier and sidebands in radio transmission", Proceedings of the Institute of Radio Engineers 11:34.1924, "The transmission unit", Electrical Communications 3:34.1926, "Transmission limits of telephone lines", Bell Laboratories Record 1:225. 1928, "Transmission of information", Bell Systems Technical Journal (July).1928, "“TU” becomes Decibel", Bell Laboratories Record 7:137.1936, "Oscillations in systems with non-linear reactance", Bell System Technology Journal 15: 424.Further ReadingM.D.Fagen (ed.), 1975, A History of Engineering \& Science in the Bell System, Vol. 1: Bell Laboratories.KF -
45 Heaviside, Oliver
[br]b. 18 May 1850 London, Englandd. 2 February 1925 Torquay, Devon, England[br]English physicist who correctly predicted the existence of the ionosphere and its ability to reflect radio waves.[br]Brought up in poor, almost Dickensian, circumstances, at the age of 13 years Heaviside, a nephew by marriage of Sir Charles Wheatstone, went to Camden House Grammar School. There he won a medal for science, but he was forced to leave because his parents could not afford the fees. After a year of private study, he began his working life in Newcastle in 1870 as a telegraph operator for an Anglo-Dutch cable company, but he had to give up after only four years because of increasing deafness. He therefore proceeded to spend his time studying theoretical aspects of electrical transmission and communication, and moved to Devon with his parents in 1889. Because the operation of many electrical circuits involves transient phenomena, he found it necessary to develop what he called operational calculus (which was essentially a form of the Laplace transform calculus) in order to determine the response to sudden voltage and current changes. In 1893 he suggested that the distortion that occurred on long-distance telephone lines could be reduced by adding loading coils at regular intervals, thus creating a matched-transmission line. Between 1893 and 1912 he produced a series of writings on electromagnetic theory, in one of which, anticipating a conclusion of Einstein's special theory of relativity, he put forward the idea that the mass of an electric charge increases with its velocity. When it was found that despite the curvature of the earth it was possible to communicate over very great distances using radio signals in the so-called "short" wavebands, Heaviside suggested the presence of a conducting layer in the ionosphere that reflected the waves back to earth. Since a similar suggestion had been made almost at the same time by Arthur Kennelly of Harvard, this layer became known as the Kennelly-Heaviside layer.[br]Principal Honours and DistinctionsFRS 1891.

46 Zworykin, Vladimir Kosma
[br]b. 30 July 1889 Mourum (near Moscow), Russiad. 29 July 1982 New York City, New York, USA[br]Russian (naturalized American 1924) television pioneer who invented the iconoscope and kinescope television camera and display tubes.[br]Zworykin studied engineering at the Institute of Technology in St Petersburg under Boris Rosing, assisting the latter with his early experiments with television. After graduating in 1912, he spent a time doing X-ray research at the Collège de France in Paris before returning to join the Russian Marconi Company, initially in St Petersburg and then in Moscow. On the outbreak of war in 1917, he joined the Russian Army Signal Corps, but when the war ended in the chaos of the Revolution he set off on his travels, ending up in the USA, where he joined the Westinghouse Corporation. There, in 1923, he filed the first of many patents for a complete system of electronic television, including one for an all-electronic scanning pick-up tube that he called the iconoscope. In 1924 he became a US citizen and invented the kinescope, a hard-vacuum cathode ray tube (CRT) for the display of television pictures, and the following year he patented a camera tube with a mosaic of photoelectric elements and gave a demonstration of still-picture TV. In 1926 he was awarded a PhD by the University of Pittsburgh and in 1928 he was granted a patent for a colour TV system.In 1929 he embarked on a tour of Europe to study TV developments; on his return he joined the Radio Corporation of America (RCA) as Director of the Electronics Research Group, first at Camden and then Princeton, New Jersey. Securing a budget to develop an improved CRT picture tube, he soon produced a kinescope with a hard vacuum, an indirectly heated cathode, a signal-modulation grid and electrostatic focusing. In 1933 an improved iconoscope camera tube was produced, and under his direction RCA went on to produce other improved types of camera tube, including the image iconoscope, the orthicon and image orthicon and the vidicon. The secondary-emission effect used in many of these tubes was also used in a scintillation radiation counter. In 1941 he was responsible for the development of the first industrial electron microscope, but for most of the Second World War he directed work concerned with radar, aircraft fire-control and TV-guided missiles.After the war he worked for a time on high-speed memories and medical electronics, becoming Vice-President and Technical Consultant in 1947. He "retired" from RCA and was made an honorary vice-president in 1954, but he retained an office and continued to work there almost up until his death; he also served as Director of the Rockefeller Institute for Medical Research from 1954 until 1962.[br]Principal Honours and DistinctionsZworykin received some twenty-seven awards and honours for his contributions to television engineering and medical electronics, including the Institution of Electrical Engineers Faraday Medal 1965; US Medal of Science 1966; and the US National Hall of Fame 1977.Bibliography29 December 1923, US patent no. 2,141, 059 (the original iconoscope patent; finally granted in December 1938!).13 July 1925, US patent no. 1,691, 324 (colour television system).1930, with D.E.Wilson, Photocells and Their Applications, New York: Wiley. 1934, "The iconoscope.
