  • 12 Goldmark, Peter Carl

    [br]
    b. 2 December 1906 Budapest, Hungary
    d. 7 December 1977 Westchester Co., New York, USA
    [br]
    Austro-Hungarian engineer who developed the first commercial colour television system and the long-playing record.
    [br]
    After education in Hungary and a period as an assistant at the Technische Hochschule, Berlin, Goldmark moved to England, where he joined Pye of Cambridge and worked on an experimental thirty-line television system using a cathode ray tube (CRT) for the display. In 1936 he moved to the USA to work at Columbia Broadcasting Laboratories. There, with monochrome television based on the CRT virtually a practical proposition, he devoted his efforts to finding a way of producing colour TV images: in 1940 he gave his first demonstration of a working system. There then followed a series of experimental field-sequential colour TV systems based on segmented red, green and blue colour wheels and drums, where the problem was to find an acceptable compromise between bandwidth, resolution, colour flicker and colour-image breakup. Eventually he arrived at a system using a colour wheel in combination with a CRT containing a panchromatic phosphor screen, with a scanned raster of 405 lines and a primary colour rate of 144 fields per second. Despite the fact that the receivers were bulky, gave relatively poor, dim pictures and used standards totally incompatible with the existing 525-line, sixty fields per second interlaced monochrome (black and white) system, in 1950 the Federal Communications Commission (FCC), anxious to encourage postwar revival of the industry, authorized the system for public broadcasting. Within eighteen months, however, bowing to pressure from the remainder of the industry, which had formed its own National Television Systems Committee (NTSC) to develop a much more satisfactory, fully compatible system based on the RCA three-gun shadowmask CRT, the FCC withdrew its approval.
    While all this was going on, Goldmark had also been working on ideas for overcoming the poor reproduction, noise quality, short playing-time (about four minutes) and limited robustness and life of the long-established 78 rpm 12 in. (30 cm) diameter shellac gramophone record. The recent availability of a new, more robust, plastic material, vinyl, which had a lower surface noise, enabled him in 1948 to reduce the groove width some three times to 0.003 in. (0.0762 mm), use a more lightly loaded synthetic sapphire stylus and crystal transducer with improved performance, and reduce the turntable speed to 33 1/3 rpm, to give thirty minutes of high-quality music per side. This successful development soon led to the availability of stereophonic recordings, based on the ideas of Alan Blumlein at EMI in the 1930s.
    In 1950 Goldmark became a vice-president of CBS, but he still found time to develop a scan conversion system for relaying television pictures to Earth from the Lunar Orbiter spacecraft. He also almost brought to the market a domestic electronic video recorder (EVR) system based on the thermal distortion of plastic film by separate luminance and coded colour signals, but this was overtaken by the video cassette recorder (VCR) system, which uses magnetic tape.

    [br]
    b. 14 April 1898 Leominster, Massachusetts, USA
    d. 11 December 1983 Summitt, New Jersey, USA
    [br]
    American electrical engineer who discovered that the application of negative feedback to amplifiers improved their stability and reduced distortion.
    [br]
    Black graduated from Worcester Polytechnic Institute, Massachusetts, in 1921 and joined the Western Electric Company laboratories (later the Bell Telephone Laboratories) in New York City. There he worked on a variety of electronic-communication problems. His major contribution was the discovery in 1927 that the application of negative feedback to an amplifier, whereby a fraction of the output signal is fed back to the input in the opposite phase, not only increases the stability of the amplifier but also has the effect of reducing the magnitude of any distortion introduced by it. This discovery has found wide application in the design of audio hi-fi amplifiers and various control systems, and has also given valuable insight into the way in which many animal control functions operate.
    During the Second World War he developed a form of pulse code modulation (PCM) to provide a practicable, secure telephony system for the US Army Signal Corps. From 1963–6, after his retirement from the Bell Labs, he was Principal Research Scientist with General Precision Inc., Little Falls, New Jersey, following which he became an independent consultant in communications. At the time of his death he held over 300 patents.

  • 14 De Forest, Lee

    [br]
    b. 26 August 1873 Council Bluffs, Iowa, USA
    d. 30 June 1961 Hollywood, California, USA
    [br]
    American electrical engineer and inventor principally known for his invention of the Audion, or triode, vacuum tube; also a pioneer of sound in the cinema.
    [br]
    De Forest was born into the family of a Congregational minister that moved to Alabama in 1879 when the father became President of a college for African-Americans; this was a position that led to the family's social ostracism by the white community. By the time he was 13 years old, De Forest was already a keen mechanical inventor, and in 1893, rejecting his father's plan for him to become a clergyman, he entered the Sheffield Scientific School of Yale University. Following his first degree, he went on to study the propagation of electromagnetic waves, gaining a PhD in physics in 1899 for his thesis on the "Reflection of Hertzian Waves from the Ends of Parallel Wires", probably the first US thesis in the field of radio.
    He then joined the Western Electric Company in Chicago where he helped develop the infant technology of wireless, working his way up from a modest post in the production area to a position in the experimental laboratory. There, working alone after normal working hours, he developed a detector of electromagnetic waves based on an electrolytic device similar to that already invented by Fleming in England. Recognizing his talents, a number of financial backers enabled him to set up his own business in 1902 under the name of De Forest Wireless Telegraphy Company; he was soon demonstrating wireless telegraphy to interested parties and entering into competition with the American Marconi Company.
    Despite the failure of this company because of fraud by his partners, he continued his experiments; in 1907, by adding a third electrode, a wire mesh, between the anode and cathode of the thermionic diode invented by Fleming in 1904, he was able to produce the amplifying device now known as the triode valve and achieve a sensitivity of radio-signal reception much greater than possible with the passive carborundum and electrolytic detectors hitherto available. Patented under the name Audion, this new vacuum device was soon successfully used for experimental broadcasts of music and speech in New York and Paris. The invention of the Audion has been described as the beginning of the electronic era. Although much development work was required before its full potential was realized, the Audion opened the way to progress in all areas of sound transmission, recording and reproduction. The patent was challenged by Fleming and it was not until 1943 that De Forest's claim was finally recognized.
    Overcoming the near failure of his new company, the De Forest Radio Telephone Company, as well as unsuccessful charges of fraudulent promotion of the Audion, he continued to exploit the potential of his invention. By 1912 he had used transformer-coupling of several Audion stages to achieve high gain at radio frequencies, making long-distance communication a practical proposition, and had applied positive feedback from the Audion output anode to its input grid to realize a stable transmitter oscillator and modulator. These successes led to prolonged patent litigation with Edwin Armstrong and others, and he eventually sold the manufacturing rights, in retrospect often for a pittance.
    During the early 1920s De Forest began a fruitful association with T.W.Case, who for around ten years had been working to perfect a moving-picture sound system. De Forest claimed to have had an interest in sound films as early as 1900, and Case now began to supply him with photoelectric cells and primitive sound cameras. He eventually devised a variable-density sound-on-film system utilizing a glow-discharge modulator, the Photion. By 1926 De Forest's Phonofilm had been successfully demonstrated in over fifty theatres and this system became the basis of Movietone. Though his ideas were on the right lines, the technology was insufficiently developed and it was left to others to produce a system acceptable to the film industry. However, De Forest had played a key role in transforming the nature of the film industry; within a space of five years the production of silent films had all but ceased.
    In the following decade De Forest applied the Audion to the development of medical diathermy. Finally, after spending most of his working life as an independent inventor and entrepreneur, he worked for a time during the Second World War at the Bell Telephone Laboratories on military applications of electronics.

    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.

    b. 11 January 1872 Austin, Texas, USA
    d. 25 August 1956 Franklin, New Hampshire, USA
    [br]
    American physicist who made various contributions to electronics, particularly crystal oscillators.
    [br]
    Pierce entered the University of Texas in 1890, gaining his BSc in physics in 1893 and his MSc in 1894. After teaching and doing various odd jobs, in 1897 he obtained a scholarship to Harvard, obtaining his PhD three years later. Following a period at the University of Leipzig, he returned to the USA in 1903 to join the teaching staff at Harvard, where he soon established new courses and began to gain a reputation as a pioneer in electronics, including the study of crystal rectifiers and publication of a textbook on wireless telegraphy. In 1912, with Kennelly, he conceived the idea of motional impedance. The same year he was made first Director of Harvard's Cruft High- Tension Electrical Laboratory, a post he held until his retirement. In 1917 he was appointed Professor of Physics, and for the remainder of the First World War he was also involved in work on submarine detection at the US Naval Base in New London. In 1921 he was appointed Rumford Professor of Physics and became interested in the work of Walter Cady on crystal-controlled circuits. As a result of this he patented the Pierce crystal oscillator in 1924. Having discovered the magnetostriction property of nickel and nichrome, in 1928 he also invented the magnetostriction oscillator. The mercury-vapour discharge lamp is also said to have been his idea. He became Gordon McKay Professor of Physics and Communications in 1935 and retired from Harvard in 1940, but he remained active for the rest of his life with the study of sound generation by birds and insects.

    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]
    b. 27 March 1910 Des Moines, Iowa, USA
    [br]
    American scientist and communications engineer said to be the "father" of communication satellites.
    [br]
    From his high-school days, Pierce showed an interest in science and in science fiction, writing under the pseudonym of J.J.Coupling. After gaining Bachelor's, Master's and PhD degrees at the California Institute of Technology (CalTech) in Pasadena in 1933, 1934 and 1936, respectively, Pierce joined the Bell Telephone Laboratories in New York City in 1936. There he worked on improvements to the travelling-wave tube, in which the passage of a beam of electrons through a helical transmission line at around 7 per cent of the speed of light was made to provide amplification at 860 MHz. He also devised a new form of electrostatically focused electron-multiplier which formed the basis of a sensitive detector of radiation. However, his main contribution to electronics at this time was the invention of the Pierce electron gun—a method of producing a high-density electron beam. In the Second World War he worked with McNally and Shepherd on the development of a low-voltage reflex klystron oscillator that was applied to military radar equipment.
    In 1952 he became Director of Electronic Research at the Bell Laboratories' establishment, Murray Hill, New Jersey. Within two years he had begun work on the possibility of round-the-world relay of signals by means of communication satellites, an idea anticipated in his early science-fiction writings (and by Arthur C. Clarke in 1945), and in 1955 he published a paper in which he examined various possibilities for communications satellites, including passive and active satellites in synchronous and non-synchronous orbits. In 1960 he used the National Aeronautics and Space Administration 30 m (98 1/2 ft) diameter, aluminium-coated Echo 1 balloon satellite to reflect telephone signals back to earth. The success of this led to the launching in 1962 of the first active relay satellite (Telstar), which weighed 170 lb (77 kg) and contained solar-powered rechargeable batteries, 1,000 transistors and a travelling-wave tube capable of amplifying the signal 10,000 times. With a maximum orbital height of 3,500 miles (5,600 km), this enabled a variety of signals, including full bandwidth television, to be relayed from the USA to large receiving dishes in Europe.
    From 1971 until his "retirement" in 1979, Pierce was Professor of Electrical Engineering at CalTech, after which he became Chief Technologist at the Jet Propulsion Laboratories, also in Pasadena, and Emeritus Professor of Engineering at Stanford University.

    [br]
    b. 1 January 1874 Chicago, Illinois, USA
    d. 11 December 1961 Claremont, California, USA
    [br]
    American radio engineer whose work on radio-detection helped lay the foundations for radar.
    [br]
    Taylor gained his degree in engineering from Northwest University, Evanston, Illinois, then spent a time at the University of Gottingen. On his return to the USA he taught successively at Michigan State University, at Lansing, and at the universities of Wisconsin at Madison and North Dakota at Grand Forks. From 1923 until 1945 he supervised the Radio Division at the US Naval Research Laboratories. There he carried out studies of short-wave radio propagation and confirmed Heaviside's 1925 theory of the reflection characteristics of the ionosphere. In the 1920s and 1930s he investigated radio echoes, and in 1933, with L.C.Young and L.A.Hyland, he filed a patent for a system of radio-detection that contributed to the subsequent development of radar.
