2 Eisler, Paul
[br]b. 1907 Vienna, Austria[br]Austrian engineer responsible for the invention of the printed circuit.[br]At the age of 23, Eisler obtained a Diploma in Engineering from the Technical University of Vienna. Because of the growing Nazi influence in Austria, he then accepted a post with the His Master's Voice (HMV) agents in Belgrade, where he worked on the problems of radio reception and sound transmission in railway trains. However, he soon returned to Vienna to found a weekly radio journal and file patents on graphical sound recording (for which he received a doctorate) and on a system of stereoscopic television based on lenticular vertical scanning.In 1936 he moved to England and sold the TV patent to Marconi for £250. Unable to find a job, he carried out experiments in his rooms in a Hampstead boarding-house; after making circuits using strip wires mounted on bakelite sheet, he filed his first printed-circuit patent that year. He then tried to find ways of printing the circuits, but without success. Obtaining a post with Odeon Theatres, he invented a sound-level control for films and devised a mirror-drum continuous-film projector, but with the outbreak of war in 1939, when the company was evacuated, he chose to stay in London and was interned for a while. Released in 1941, he began work with Henderson and Spalding, a firm of lithographic printers, to whom he unwittingly assigned all future patents for the paltry sum of £1. In due course he perfected a means of printing conducting circuits and on 3 February 1943 he filed three patents covering the process. The British Ministry of Defence rejected the idea, considering it of no use for military equipment, but after he had demonstrated the technique to American visitors it was enthusiastically taken up in the US for making proximity fuses, of which many millions were produced and used for the war effort. Subsequently the US Government ruled that all air-borne electronic circuits should be printed.In the late 1940s the Instrument Department of Henderson and Spalding was split off as Technograph Printed Circuits Ltd, with Eisler as Technical Director. In 1949 he filed a further patent covering a multilayer system; this was licensed to Pye and the Telegraph Condenser Company. A further refinement, patented in the 1950s, the use of the technique for telephone exchange equipment, but this was subsequently widely infringed and although he negotiated licences in the USA he found it difficult to license his ideas in Europe. In the UK he obtained finance from the National Research and Development Corporation, but they interfered and refused money for further development, and he eventually resigned from Technograph. Faced with litigation in the USA and open infringement in the UK, he found it difficult to establish his claims, but their validity was finally agreed by the Court of Appeal (1969) and the House of Lords (1971).As a freelance inventor he filed many other printed-circuit patents, including foil heating films and batteries. When his Patent Agents proved unwilling to fund the cost of filing and prosecuting Complete Specifications he set up his own company, Eisler Consultants Ltd, to promote food and space heating, including the use of heated cans and wallpaper! As Foil Heating Ltd he went into the production of heating films, the process subsequently being licensed to Thermal Technology Inc. in California.[br]Bibliography1953, "Printed circuits: some general principles and applications of the foil technique", Journal of the British Institution of Radio Engineers 13: 523.1959, The Technology of Printed Circuits: The Foil Technique in Electronic Production.1984–5, "Reflections of my life as an inventor", Circuit World 11:1–3 (a personal account of the development of the printed circuit).1989, My Life with the Printed Circuit, Bethlehem, Pennsylvania: Lehigh University Press.KF -
3 Appleton, Sir Edward Victor
[br]b. 6 September 1892 Bradford, Englandd. 21 April 1965 Edinburgh, Scotland[br]English physicist awarded the Nobel Prize for Physics for his discovery of the ionospheric layer, named after him, which is an efficient reflector of short radio waves, thereby making possible long-distance radio communication.[br]After early ambitions to become a professional cricketer, Appleton went to St John's College, Cambridge, where he studied under J.J.Thompson and Ernest Rutherford. His academic career interrupted by the First World War, he served as a captain in the Royal Engineers, carrying out investigations into the propagation and fading of radio signals. After the war he joined the Cavendish Laboratory, Cambridge, as a demonstrator in 1920, and in 1924 he moved to King's College, London, as Wheatstone Professor of Physics.In the following decade he contributed to developments in valve oscillators (in particular, the "squegging" oscillator, which formed the basis of the first hard-valve time-base) and gained international recognition for research into electromagnetic-wave propagation. His most important contribution was to confirm the existence of a conducting ionospheric layer in the upper atmosphere capable of reflecting radio waves, which had been predicted almost simultaneously by Heaviside and Kennelly in 1902. This he did by persuading the BBC in 1924 to vary the frequency of their Bournemouth transmitter, and he then measured the signal received at Cambridge. By comparing the direct and reflected rays and the daily variation he was able to deduce that the Kennelly- Heaviside (the so-called E-layer) was at a height of about 60 miles (97 km) above the earth and that there was a further layer (the Appleton or F-layer) at about 150 miles (240 km), the latter being an efficient reflector of the shorter radio waves that penetrated the lower layers. During the period 1927–32 and aided by Hartree, he established a magneto-ionic theory to explain the existence of the ionosphere. He was instrumental in obtaining agreement for international co-operation for ionospheric and other measurements in the form of the Second Polar Year (1932–3) and, much later, the International Geophysical Year (1957–8). For all this work, which made it possible to forecast the optimum frequencies for long-distance short-wave communication as a function of the location of transmitter and receiver and of the time of day and year, in 1947 he was awarded the Nobel Prize for Physics.He returned to Cambridge as Jacksonian Professor of Natural Philosophy in 1939, and with M.F. Barnett he investigated the possible use of radio waves for radio-location of aircraft. In 1939 he became Secretary of the Government Department of Scientific and Industrial Research, a post he held for ten years. During the Second World War he contributed to the development of both radar and the atomic bomb, and subsequently served on government committees concerned with the use of atomic energy (which led to the establishment of Harwell) and with scientific staff.[br]Principal Honours and DistinctionsKnighted (KCB 1941, GBE 1946).
