  • 6 Kompfner, Rudolph

    [br]
    b. 16 May 1909 Vienna, Austria
    d. 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.

    SUBJECT AREA: Weapons and armour
    [br]
    b. 23 August 1885 Gillingham, Kent, England
    d. 9 October 1959 Fareham, Hampshire, England
    [br]
    English scientist and administrator who made many contributions to military technology.
    [br]
    Educated at Westminster College, in 1904 Tizard went to Magdalen College, Oxford, gaining Firsts in mathematics and chemistry. After a period of time in Berlin with Nernst, he joined the Royal Institution in 1909 to study the colour changes of indicators. From 1911 until 1914 he was a tutorial Fellow of Oriel College, Oxford, but with the outbreak of the First World War he joined first the Royal Garrison Artillery, then, in 1915, the newly formed Royal Flying Corps, to work on the development of bomb-sights. Successively in charge of testing aircraft, a lieutenant-colonel in the Ministry of Munitions and Assistant Controller of Research and Experiments for the Royal Air Force, he returned to Oxford in 1919 and the following year became Reader in Chemical Thermodynamics; at this stage he developed the use of toluene as an air-craft-fuel additive.
    In 1922 he was appointed an assistant secretary at the government Department of Industrial and Scientific Research, becoming Principal Assistant Secretary in 1922 and its Permanent Director in 1927; during this time he was also a member of the Aeronautical Research Committee, being Chairman of the latter in 1933–43. From 1929 to 1942 he was Rector of Imperial College. In 1932 he was also appointed Chairman of a committee set up to investigate possible national air-defence systems, and it was largely due to his efforts that the radar proposals of Watson-Watt were taken up and an effective system made operational before the outbreak of the Second World War. He was also involved in various other government activities aimed at applying technology to the war effort, including the dam-buster and atomic bombs.
    President of Magdalen College in 1942–7, he then returned again to Whitehall, serving as Chairman of the Advisory Council on Scientific Policy and of the Defence Research Policy Committee. Finally, in 1952, he became Pro-Chan-cellor of Southampton University.

    [br]
    b. 18 October 1863 Kimmerghame, Berwickshire, Scotland
    d. 19 February 1930 London, England
    [br]
    Scottish electrical engineer who correctly predicted the development of electronic television.
    [br]
    After a time at Cargilfield Trinity School, Campbell-Swinton went to Fettes College in Edinburgh from 1878 to 1881 and then spent a year abroad in France. From 1882 until 1887 he was employed at Sir W.G.Armstrong's works in Elswick, Newcastle, following which he set up his own electrical contracting business in London. This he gave up in 1904 to become a consultant. Subsequently he was an engineer with many industrial companies, including the W.T.Henley Telegraph Works Company, Parson Marine Steam Turbine Company and Crompton Parkinson Ltd, of which he became a director. During this time he was involved in electrical and scientific research, being particularly associated with the development of the Parson turbine.
    In 1903 he tried to realize distant electric vision by using a Braun oscilloscope tube for the. image display, a second tube being modified to form a synchronously scanned camera, by replacing the fluorescent display screen with a photoconductive target. Although this first attempt at what was, in fact, a vidicon camera proved unsuccessful, he was clearly on the right lines and in 1908 he wrote a letter to Nature with a fairly accurate description of the principles of an all-electronic television system using magnetically deflected cathode ray tubes at the camera and receiver, with the camera target consisting of a mosaic of photoconductive elements that were scanned and discharged line by line by an electron beam. He expanded on his ideas in a lecture to the Roentgen Society, London, in 1911, but it was over twenty years before the required technology had advanced sufficiently for Shoenberg's team at EMI to produce a working system.

    Colpitts obtained Bachelor's degrees at Mount Allison University, Sackville, New Brunswick, and Harvard in 1894 and 1896, respectively, followed by a Master's degree at Harvard in 1897. After two years as assistant to the professor of physics there, he joined the American Bell Telephone Company. When the Bell Company was reorganized in 1907, he moved to the Western Electric branch of the company in New York as Head of the Physical Laboratories. In 1911 he became a director of the Research Laboratories, and in 1917 he became Assistant Chief Engineer of the company. During this time he invented both the push-pull amplifier and the Colpitts oscillator, both major developments in communications. In 1917, during the First World War, he spent some time in France helping to set up the US Signal Corps Research Laboratories. Afterwards he continued to do much, both technically and as a manager, to place telephone communications on a firm scientific basis, retiring as Vice-President of the Bell Telephone Laboratories in 1937. With the outbreak of the Second World War in 1941 he was recalled from retirement and appointed Director of the Engineering Foundation to work on submarine warfare techniques, particularly echo-ranging.

  • 10 Hofmann, August Wilhelm von

    SUBJECT AREA: Chemical technology
    [br]
    b. 8 April 1818 Giessen, Germany
    d. 2 May 1892 Berlin, Germany
    [br]
    German organic chemist.
    [br]
    The son of an architect, Hofmann began studying law and languages but was increasingly drawn to chemistry, attracted by Liebig's teaching at Giessen. In 1841 Hofmann took his doctorate with a study of coal tar. He became Privatdozent at Bonn University in 1845, but later that year he was persuaded to take up the post of first Director of the Royal College of Chemistry in London, after tenure was guaranteed as a result of Prince Albert's influence. He remained there for twenty years until he was offered professorships in chemistry at Bonn and Berlin. He accepted the latter. Hofmann continued the method of teaching chemistry, based on laboratory instruction, developed by Liebig at Giessen, and extended it to England and Berlin. A steady stream of well-trained chemists issued forth from Hofmann's tuition, concerning themselves especially with experimental organic chemistry and the industrial applications of chemistry. In 1848 one of his students, C.B. Mansfield, devised the method of fractional distillation of coal tar, to separate pure benzene, xylene and toluene, thus laying the foundations of the coal-tar industry. In 1856 another student, W.H. Perkin, prepared the first synthetic dyestuff, aniline purple, heralding the great dyestuffs industry, in which several other of his students distinguished themselves. Although keenly interested in the chemistry of dyestuffs, Hofmann did not pursue their large-scale preparation, but he stressed the importance of scientific research for success on a commercial scale. Hofmann's stimulus in this direction flagged after his return to Germany, and this was a factor in the failure of British industry to follow up their initial advantage and allow it to pass to Germany. In 1862 Hofmann prepared a dye from a derivative of triphenylmethane, which he called rosaniline. From this he derived a series of beautiful colours, ranging from blue to violet, which he patented as "Hofmann's violets" the following year.

    b. 13 April 1892 Brechin, Angus, Scotland
    d. 6 December 1973 Inverness, Scotland
    [br]
    Scottish engineer and scientific adviser known for his work on radar.
    [br]
    Following education at Brechin High School, Watson-Watt entered University College, Dundee (then a part of the University of St Andrews), obtaining a BSc in engineering in 1912. From 1912 until 1921 he was Assistant to the Professor of Natural Philosophy at St Andrews, but during the First World War he also held various posts in the Meteorological Office. During. this time, in 1916 he proposed the use of cathode ray oscillographs for radio-direction-finding displays. He joined the newly formed Radio Research Station at Slough when it was opened in 1924, and 3 years later, when it amalgamated with the Radio Section of the National Physical Laboratory, he became Superintendent at Slough. At this time he proposed the name "ionosphere" for the ionized layer in the upper atmosphere. With E.V. Appleton and J.F.Herd he developed the "squegger" hard-valve transformer-coupled timebase and with the latter devised a direction-finding radio-goniometer.
    In 1933 he was asked to investigate possible aircraft counter-measures. He soon showed that it was impossible to make the wished-for radio "death-ray", but had the idea of using the detection of reflected radio-waves as a means of monitoring the approach of enemy aircraft. With six assistants he developed this idea and constructed an experimental system of radar (RAdio Detection And Ranging) in which arrays of aerials were used to detect the reflected signals and deduce the bearing and height. To realize a practical system, in September 1936 he was appointed Director of the Bawdsey Research Station near Felixstowe and carried out operational studies of radar. The result was that within two years the East Coast of the British Isles was equipped with a network of radar transmitters and receivers working in the 7–14 metre band—the so-called "chain-home" system—which did so much to assist the efficient deployment of RAF Fighter Command against German bombing raids on Britain in the early years of the Second World War.
    In 1938 he moved to the Air Ministry as Director of Communications Development, becoming Scientific Adviser to the Air Ministry and Ministry of Aircraft Production in 1940, then Deputy Chairman of the War Cabinet Radio Board in 1943. After the war he set up Sir Robert Watson-Watt \& Partners, an industrial consultant firm. He then spent some years in relative retirement in Canada, but returned to Scotland before his death.

    [br]
    b. 28 July 1915 Greenville, South Carolina, USA
    [br]
    American physicist who developed the maser and contributed to the development of the laser.
    [br]
    Charles H.Townes entered Furman University, Greenville, at the early age of 16 and in 1935 obtained a BA in modern languages and a BS in physics. After a year of postgraduate study at Duke University, he received a master's degree in physics in 1936. He then went on to the California Institute of Technology, where he obtained a PhD in 1939. From 1939 to 1947 he worked at the Bell Telephone Laboratories, mainly on airborne radar, although he also did some work on radio astronomy. In 1948 he joined Columbia University as Associate Professor of Physics and in 1950 was appointed a full professor. He was Director of the University's Radiation Laboratory from 1950 to 1952, and from 1952 to 1955 he was Chairman of the Physics Department.
    To meet the need for an oscillator generating very short wavelength electromagnetic radiation, Townes in 1951 realized that use could be made of the different natural energy levels of atoms and molecules. The practical application of this idea was achieved in his laboratory in 1953 using ammonia gas to make the device known as a maser (an acronym of microwave amplification by stimulated emission of radiation). The maser was developed in the next few years and in 1958, in a joint paper with his brother-in-law Arthur L. Schawlow, Townes suggested the possibility of a further development into optical frequencies or an optical maser, later known as a laser (an acronym of light amplification by stimulated emission of radiation). Two years later the first such device was made by Theodore H. Maiman.
    In 1959 Townes was given leave from Columbia University to serve as Vice-President and Director of Research at the Institute for Defense Analyses until 1961. He was then appointed Provost and Professor of Physics at the Massachusetts Institute of Technology. In 1967 he became University Professor of Physics at the University of California, where he has extended his research interests in the field of microwave and infra-red astronomy. He is a member of the National Academy of Sciences, the Institute of Electrical and Electronics Engineers and the American Astronomical Society.

    SUBJECT AREA: Ports and shipping
    [br]
    b. 11 June 1910 Saint-André-de-Cubzac, France
    [br]
    French marine explorer who invented the aqualung.
    [br]
    He was the son of a country lawyer who became legal advisor and travelling companion to certain rich Americans. At an early age Cousteau acquired a love of travel, of the sea and of cinematography: he made his first film at the age of 13. After an interrupted education he nevertheless passed the difficult entrance examination to the Ecole Navale in Brest, but his naval career was cut short in 1936 by injuries received in a serious motor accident. For his long recuperation he was drafted to Toulon. There he met Philippe Tailliez, a fellow naval officer, and Frédéric Dumas, a champion spearfisher, with whom he formed a long association and began to develop his underwater swimming and photography. He apparently took little part in the Second World War, but under cover he applied his photographic skills to espionage, for which he was awarded the Légion d'honneur after the war.
    Cousteau sought greater freedom of movement underwater and, with Emile Gagnan, who worked in the laboratory of Air Liquide, he began experimenting to improve portable underwater breathing apparatus. As a result, in 1943 they invented the aqualung. Its simple design and robust construction provided a reliable and low-cost unit and revolutionized scientific and recreational diving. Gagnan shunned publicity, but Cousteau revelled in the new freedom to explore and photograph underwater and exploited the publicity potential to the full.
    The Undersea Research Group was set up by the French Navy in 1944 and, based in Toulon, it provided Cousteau with the Opportunity to develop underwater exploration and filming techniques and equipment. Its first aims were minesweeping and exploration, but in 1948 Cousteau pioneered an extension to marine archaeology. In 1950 he raised the funds to acquire a surplus US-built minesweeper, which he fitted out to further his quest for exploration and adventure and named Calypso. Cousteau also sought and achieved public acclaim with the publication in 1953 of The Silent World, an account of his submarine observations, illustrated by his own brilliant photography. The book was an immediate success and was translated into twenty-two languages. In 1955 Calypso sailed through the Red Sea and the western Indian Ocean, and the outcome was a film bearing the same title as the book: it won an Oscar and the Palme d'Or at the Cannes film festival. This was his favoured medium for the expression of his ideas and observations, and a stream of films on the same theme kept his name before the public.
    Cousteau's fame earned him appointment by Prince Rainier as Director of the Oceanographie Institute in Monaco in 1957, a post he held until 1988. With its museum and research centre, it offered Cousteau a useful base for his worldwide activities.
    In the 1980s Cousteau turned again to technological development. Like others before him, he was concerned to reduce ships' fuel consumption by harnessing wind power. True to form, he raised grants from various sources to fund research and enlisted technical help, namely Lucien Malavard, Professor of Aerodynamics at the Sorbonne. Malavard designed a 44 ft (13.4 m) high non-rotating cylinder, which was fitted onto a catamaran hull, christened Moulin à vent. It was intended that its maiden Atlantic crossing in 1983 should herald a new age in ship propulsion, with large royalties to Cousteau. Unfortunately the vessel was damaged in a storm and limped to the USA under diesel power. A more robust vessel, the Alcyone, was fitted with two "Turbosails" in 1985 and proved successful, with a 40 per cent reduction in fuel consumption. However, oil prices fell, removing the incentive to fit the new device; the lucrative sales did not materialize and Alcyone remained the only vessel with Turbosails, sharing with Calypso Cousteau's voyages of adventure and exploration. In September 1995, Cousteau was among the critics of the decision by the French President Jacques Chirac to resume testing of nuclear explosive devices under the Mururoa atoll in the South Pacific.

    d. 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.

    French physician and physicist noted for his invention of the reflecting galvanometer and for contributions to electrotherapy.
    [br]
    After studies at colleges in Limoges and later in Paris, Arsonval became a doctor of medicine in 1877. In 1882 the Collège de France established a laboratory of biophysics with Arsonval as Director, and he was Professor from 1894.
    His most outstanding scientific contributions were in the field of biological applications of electricity. His interest in muscle currents led to a series of inventions to assist in research, including the moving-coil galvanometer. In 1881 he made a significant improvement to the galvanometer by reversing the magnetic elements. It had been usual to suspend a compass needle in the centre of a large, stationary coil, but Arsonval's invention was to suspend a small, light coil between the poles of a powerful fixed magnet. This simple arrangement was independent of the earth's magnetic field and insensitive to vibration. A great increase in sensitivity was achieved by attaching a mirror to the coil in order to reflect a spot of light. For bacterial-research purposes he designed the first constant-temperature incubator controlled by electricity. His experiments on the effects of high-frequency, low-voltage alternating currents on animals led to the first high-frequency heat-therapy unit being established in 1892, and later to methods of physiotherapy becoming a professional discipline.

    [br]
    After schooling in France and Germany, Krylov returned to St Petersburg (as it then was) and in 1878 entered the Naval College. Upon graduating, he started work with the Naval Hydrographic Department; the combination of his genius and breadth of interest became apparent, and from 1888 until 1890 he undertook simultaneously a two-year university course in mathematics and a naval architecture course at his old college. On completion of his formal studies, Krylov commenced fifty years of service to the academic bodies of St Petersburg, including eight years as Superintendent of the Russian Admiralty Ship Model Experiment Tank. For many years he was Professor of Naval Architecture in the city, reorganizing the methods of teaching of his profession in Russia. It was during this period that he laid the foundations of his remarkable research and published the first of his many books destined to become internationally accepted in the fields of waves, rolling, ship motion and vibration. Practical work was not overlooked: he was responsible for the design of many vessels for the Imperial Russian Navy, including the battleships Sevastopol and Petropavlovsk, and went on, as Director of Naval Construction, to test anti-rolling tanks aboard military vessels in the North Atlantic in 1913. Following the Revolution, Krylov was employed by the Soviet Union to re-establish scientific links with other European countries, and on several occasions he acted as Superintendent in the procurement of important technical material from overseas. In 1919 he was appointed Head of the Marine Academy, and from then on participated in many scientific conferences and commissions, mainly in the shipbuilding field, and served on the Editorial Board of the well-respected Russian periodical Sudostroenie (Shipbuilding). The breadth of his personal research was demonstrated by the notable contributions he made to the Russian development of the gyro compass.

    b. 1845 Dukinfield, Cheshire, England
    d. 1 October 1921 Pontefract, Yorkshire, England
    [br]
    English colliery manager, pioneer in machine-holing and the safety of mines.
    [br]
    After Menzies conceived his idea of breaking off coal with machines in 1761, many inventors subsequently followed his proposals through into the practice of underground working. More than one century later, Garforth became one of the principal pioneers of machine-holing combined with the longwall method of working in order to reduce production costs and increase the yield of coal. Having been appointed agent to Pope \& Pearson's Collieries, West Yorkshire, in 1879, of which company he later became Managing Director and Chairman, he gathered a great deal of experience with different methods of cutting coal. The first disc machine was exhibited in London as early as 1851, and ten years later a pick machine was invented. In 1893 he introduced an improved type of deep undercutting machine, his "diamond" disc coal-cutter, driven by compressed air, which also became popular on the European continent.
    Besides the considerable economic advantages it created, the use of machinery for mining coal increased the safety of working in hard and thin seams. The improvement of safety in mining technology was always his primary concern, and as a result of his inventions and his many publications he became the leading figure in the British coal mining industry at the beginning of the twentieth century; safety lamps still carry his name. In 1885 he invented a firedamp detector, and following a severe explosion in 1886 he concentrated on coal-dust experiments. From the information he obtained of the effect of stone-dust on a coal-dust explosion he proposed the stone-dust remedy to prevent explosions of coal-dust. As a result of discussions which lasted for decades and after he had been entrusted with the job of conducting the British coal-dust experiments, in 1921 an Act made it compulsory in all mines which were not naturally wet throughout to treat all roads with incombustible dust so as to ensure that the dust always consisted of a mixture containing not more than 50 per cent combustible matter. In 1901 Garforth erected a surface gallery which represented the damaged roadways of a mine and could be filled with noxious fumes to test self-contained breathing apparata. This gallery formed the model from which all the rescue-stations existing nowadays have been developed.

    b. 16 August 1845 Hallerick, Luxembourg
    d. 14 July 1921 at sea, in the North Atlantic
    [br]
    French physicist who developed interference colour photography.
    [br]
    Born of French parents, Lippman's work began with a distinguished career in classics, philosophy, mathematics and physics at the Ecole Normale in Luxembourg. After further studies in physics at Heidelberg University, he returned to France and the Sorbonne, where he was in 1886 appointed Director of Physics. He was a leading pioneer in France of research into electricity, optics, heat and other branches of physics.
    In 1886 he conceived the idea of recording the existence of standing waves in light when it is reflected back on itself, by photographing the colours so produced. This required the production of a photographic emulsion that was effectively grainless: the individual silver halide crystals had to be smaller than the shortest wavelength of light to be recorded. Lippman succeeded in this and in 1891 demonstrated his process. A glass plate was coated with a grainless emulsion and held in a special plate-holder, glass towards the lens. The back of the holder was filled with mercury, which provided a perfect reflector when in contact with the emulsion. The standing waves produced during the exposure formed laminae in the emulsion, with the number of laminae being determined by the wavelength of the incoming light at each point on the image. When the processed plate was viewed under the correct lighting conditions, a theoretically exact reproduction of the colours of the original subject could be seen. However, the Lippman process remained a beautiful scientific demonstration only, since the ultra-fine-grain emulsion was very slow, requiring exposure times of over 10,000 times that of conventional negative material. Any method of increasing the speed of the emulsion also increased the grain size and destroyed the conditions required for the process to work.
