The son of an electrical engineer, Theodore H. Maiman graduated with the degree of BS in engineering physics from the University of Colorado in 1949. He then went on to do postgraduate work at Stanford University, where he gained an MS in electrical engineering in 1951 and a PhD in physics in 1955 for work on spectroscopy using microwave-optical techniques. He then joined the Hughes Research Laboratories, where he worked on the stimulated emission of microwave energy. In this field Charles H. Townes had developed the maser (an acronym of microwave amplification by stimulated emission of radiation) and in a paper in 1958 with Arthur L. Schawlow he had suggested the possibility of a further development into optical frequencies, or, of an optical maser, later known as a laser (an acronym of light amplification by stimulated emission of radiation). Maiman was the first to achieve this when in May 1960 he operated a ruby laser and coherent light was produced for the first time. In 1962 he founded his own company, Korad Corporation, for research, development and manufacture of high-power lasers. He founded Maiman Associates in 1968, acting as consultant on lasers and optics. He was a co-founder of the Laser Video Corporation in 1972, and in 1976 he became Vice-President for advanced technology at TRW Electronics.

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.

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.

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.

Kettering gained degrees in mechanical and electrical engineering from Ohio State University. He was employed by the National Construction Register (NCR) of Dayton, Ohio, where he devised an electric motor for use in cash registers. He became Head of the Inventions Department of that company but left in 1909 to form, with the former Works Manager of NCR, Edward A. Deeds, the Dayton Engineering Laboratories (later called Delco), to develop improved lighting and ignition systems for automobiles. In the first two years of the new company he produced not only these but also the first self-starter, both of which were fitted to the Cadillac, America's leading luxury car. In 1914 he founded Dayton Metal Products and the Dayton Wright Airplane Company. Two years later Delco was bought by General Motors. In 1925 the independent research facilities of Delco were moved to Detroit and merged with General Motors' laboratories to form General Motors Research Corporation, of which Kettering was President and General Manager. (He had been Vice-President of General Motors since 1920.) In that position he headed investigations into methods of achieving maximum engine performance as well as into the nature of friction and combustion. Many other developments in the automobile field were made under his leadership, such as engine coolers, variable-speed transmissions, balancing machines, the two-way shock absorber, high-octane fuel, leaded petrol or gasoline, fast-drying lacquers, crank-case ventilators, chrome plating, and the high-compression automobile engine. Among his other activities were the establishment of the Charles Franklin Kettering Foundation for the Study of Chlorophyll and Photosynthesis at Antioch College, and the founding of the Sloan- Kettering Institute for Cancer Research in New York City. He sponsored the Fever Therapy Research Project at Miami Valley Hospital at Dayton, which developed the hypertherm, or artificial fever machine, for use in the treatment of disease. He resigned from General Motors in 1947.

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.

Since he had a long family connection with the naval base at Portsmouth, it is not surprising that Watts started to serve his apprenticeship there in 1860. He was singled out for advanced training and then in 1866 was one of three young men selected to attend the Royal School of Naval Architecture at South Kensington in London. On completing his training he joined the technical staff, then had a period as a ship overseer before going to assist William Froude for two years, an arrangement which led to a close friendship between Watts and the two Froudes. Some interesting tasks followed: the calculations for HM Armoured Ram Polyphemus; the setting up of a "calculating" section within the Admiralty; and then work as a constructor at Chatham Dockyard. In 1885 the first major change of direction took place: Watts resigned from naval service to take the post of General Manager of the Elswick shipyard of Sir W.G.Armstrong. This was a wonderful opportunity for an enthusiastic and highly qualified man, and Watts rose to the challenge. Elswick produced some of the finest warships at the end of the nineteenth century and its cruisers, such as the Esmeralda of the Chilean Navy, had a legendary name.

In 1902 he was recalled to the Navy to succeed Sir William White as Director of Naval Construction (DNC). This was one of the most exciting times ever in warship design and it was during Watts's tenure of the post that the Dreadnought class of battleship was produced, the submarine service was developed and the destroyer fleet reached high levels of performance. It has been said that Watts's distinct achievements as DNC were greater armament per ton displacement, higher speeds and better manoeuvring, greater protection and, almost as important, elegance of appearance. Watt retired in 1912 but remained a consultant to the Admiralty until 1916, and then joined the board of Armstrong Whitworth, on which he served until his death.

Coolidge obtained his BS from the Massachusetts Institute of Technology (MIT) in 1896, and his PhD (physics) from the University of Leipzig in 1899. He was appointed Assistant Professor of Physics at MIT in 1904, and in 1905 he joined the staff of the General Electric Company's research laboratory at Schenectady. In 1905 Schenectady was trying to make tungsten-filament lamps to counter the competition of the tantalum-filament lamps then being produced by their German rival Siemens. The first tungsten lamps made by Just and Hanaman in Vienna in 1904 had been too fragile for general use. Coolidge and his life-long collaborator, Colin G. Fink, succeeded in 1910 by hot-working directly dense sintered tungsten compacts into wire. This success was the result of a flash of insight by Coolidge, who first perceived that fully recrystallized tungsten wire was always brittle and that only partially work-hardened wire retained a measure of ductility. This grasped, a process was developed which induced ductility into the wire by hot-working at temperatures below those required for full recrystallization, so that an elongated fibrous grain structure was progressively developed. Sintered tungsten ingots were swaged to bar at temperatures around 1,500°C and at the end of the process ductile tungsten filament wire was drawn through diamond dies around 550°C. This process allowed General Electric to dominate the world lamp market. Tungsten lamps consumed only one-third the energy of carbon lamps, and for the first time the cost of electric lighting was reduced to that of gas. Between 1911 and 1914, manufacturing licences for the General Electric patents had been granted for most of the developed work. The validity of the General Electric monopoly was bitterly contested, though in all the litigation that followed, Coolidge's fibering principle was upheld. Commercial arrangements between General Electric and European producers such as Siemens led to the name "Osram" being commonly applied to any lamp with a drawn tungsten filament. In 1910 Coolidge patented the use of thoria as a particular additive that greatly improved the high-temperature strength of tungsten filaments. From this development sprang the technique of "dispersion strengthening", still being widely used in the development of high-temperature alloys in the 1990s. In 1913 Coolidge introduced the first controllable hot-cathode X-ray tube, which had a tungsten target and operated in vacuo rather than in a gaseous atmosphere. With this equipment, medical radiography could for the first time be safely practised on a routine basis. During the First World War, Coolidge developed portable X-ray units for use in field hospitals, and between the First and Second World Wars he introduced between 1 and 2 million X-ray machines for cancer treatment and for industrial radiography. He became Director of the Schenectady laboratory in 1932, and from 1940 until 1944 he was Vice-President and Director of Research. After retirement he was retained as an X-ray consultant, and in this capacity he attended the Bikini atom bomb trials in 1946. Throughout the Second World War he was a member of the National Defence Research Committee.

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.

With an early bias towards science, Daniell's interest in chemistry was formed when he joined a relative's sugar-refining business. He formed a lifelong friendship with W.T.Brande, Professor of Chemistry at the Royal Institution, and together they revived the journal of the Royal Institution, to which Daniell submitted many of his early papers on chemical subjects. He made many contributions to the science of meteorology and in 1820 invented a hydrometer, which became widely used and gave precision to the measurement of atmospheric moisture. As one of the originators of the Society for Promoting Useful Knowledge, Daniell edited several of its early publications. His work on crystallization established his reputation as a chemist and in 1831 he was appointed the first Professor of Chemistry at King's College, London, where he was largely responsible for establishing its department of applied science. He was also involved in the Chemical Society of London and served as its Vice-President. At King's College he began the research into current electricity with which his name is particularly associated. His investigations into the zinc-copper cell revealed that the rapid decline in power was due to hydrogen gas being liberated at the positive electrode. Daniell's cell, invented in 1836, employed a zinc electrode in dilute sulphuric acid and a copper electrode in a solution of copper sulphate, the electrodes being separated by a porous membrane, typically an unglazed earthenware pot. He was awarded the Copley Medal of the Royal Society for his invention which avoided the "polarization" of the simple cell and provided a further source of current for electrical research and for commercial applications such as electroplating. Although the high internal resistance of the Daniell cell limited the current and the potential was only 1.1 volts, the voltage was so unchanging that it was used as a reference standard until the 1870s, when J. Lattimer Clark devised an even more stable cell.

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.

McNeill was born in Clydebank just outside Glasgow, and was to serve that town for most of his life. After education at Clydebank High School and then at Allan Glen's in Glasgow, in 1908 he entered the shipyard of John Brown \& Co. Ltd as an apprentice. He was encouraged to matriculate at the University of Glasgow, where he studied naval architecture under the (then) unique Glasgow system of "sandwich" training, alternately spending six months in the shipyard, followed by winter at the Faculty of Engineering. On graduating in 1915, he joined the Army and by 1918 had risen to the rank of Major in the Royal Field Artillery.

After the First World War, McNeill returned to the shipyard and in 1928 was appointed Chief Naval Architect. In 1934 he was made a local director of the company. During the difficult period of the 1930s he was in charge of the technical work which led to the design, launching and successful completion of the great liners Queen Mary and Queen Elizabeth. Some of the most remarkable ships of the mid-twentieth century were to come from this shipyard, including the last British battleship, HMS Vanguard, and the Royal Yacht Britannia, completed in 1954. From 1948 until 1959, Sir James was Managing Director of the Clydebank part of the company and was Deputy Chairman by the time he retired in 1962. His public service was remarkable and included chairmanship of the Shipbuilding Conference and of the British Ship Research Association, and membership of the Committee of Lloyd's Register of Shipping.
