21 Ives, Herbert Eugene
[br]b. 1882 USAd. 1953[br]American physicist find television pioneer.[br]Ives gained his PhD in physics from Johns Hopkins University, Baltimore, Maryland, and subsequently served in the US Signal Corps, eventually gaining experience in aerial photography. He then joined the Western Electric Engineering Department (later Bell Telephone Laboratories), c.1920 becoming leader of a group concerned with television-image transmission over telephone lines. In 1927, using a Nipkow disc, he demonstrated 50-line, 18 frames/sec pictures that could be displayed as either 2 in.×2 1/2 in. (5.1 cm×6.4 cm) images suitable for a "wirephone", or 2 ft ×2 1/2 ft (61 cm×76 cm) images for television viewing. Two years later, using a single-spiral disc and three separately modulated light sources, he was able to produce full-colour images.[br]Bibliography1915, "The transformation of colour mixture equations", Journal of the Franklin Institute 180:673.1923, "do—Pt II", Journal of the Franklin Institute 195–23.1925, "Telephone picture transmission", Transactions of the Society of Motion Picture and Television Engineers 23:82.1929, "Television in colour", Bell Laboratories Record 7:439.1930, with A.L.Johnsrul, "Television in colour by a beam-scanning method", Journal of the Optical Society of America 20:11.Further ReadingJ.H.Udelson, 1982, The Great Television Race: History of the Television Industry 1925– 41: University of Alabama Press.KF -
22 Chrétien, Henri Jacques
SUBJECT AREA: Photography, film and optics[br]b. 1879 Paris, Franced. 7 February 1956 Washington, USA[br]French astrophysicist, inventor of the anamorphoser, which became the basis of the Cinemascope motion picture system.[br]Chrétien studied science, and after obtaining his bachelors degree he started his working life at Meudon Observatory. He married in 1910, the same year as he was appointed Head of Astrophysics at Nice. In 1917 he helped to found the Institut d'Optique in Paris. Chrétien became Professor of astrophysics at the Sorbonne and in 1927, as part of his work on optical systems, demonstrated the use of an anamorphic lens for wide-screen motion pictures. Although the system was demonstrated in Washington as early as 1928 and again at the Paris International Exposition of 1937, it was not until 1952 that Twentieth-Century Fox were able to complete purchase of the patents which became the basis of their Cinemascope system. Cinemascope was one of the most successful technical innovations introduced by film studios in the early 1950s as part of their attempts to combat competition from television. The first Cinemascope epic, The Robe, shown in 1953, was an outstanding commercial success, and a series of similarly spectacular productions followed.[br]Further ReadingObituary, 1956, Journal of the Society of Motion Picture and Television Engineers 65:110.R.Kingslake, 1989, A History of the Photographic Lens, Boston (biographical information and technical details of the anamorphic lens).JWBiographical history of technology > Chrétien, Henri Jacques

23 Fischer, E.
[br]fl. 1930s Switzerland[br]Swiss engineer who invented the Eidophor large-screen television projector.[br]Fischer was a professor of engineering at the Swiss Federal Institute of Technology in the late 1930s. Interested in the emerging technology for television, he was of the opinion that the growth of television would take place through the development and use of large-screen cinema-type displays serving large audiences. He therefore carried out research into suitable techniques. Realizing the brightness limitations of projection systems based on the optical magnification of the image produced by a conventional cathode ray tube, he used the deflected electron-beam, not to excite a phosphor screen, but to deposit a variable charge on the surface of a film or oil. By means of a Schlieren slit system, the consequent deformations of the surface were used to spatially modulate the light from an electric arc or a discharge tube, giving a large, high-brightness image. Although the idea, first put forward in 1939, was not taken up for cinema television, the subsequent requirement of the US National Aeronautics and Space Administration in the 1960s for large colour displays in its Command and Control Centres led to the successful development of the idea by Gretag AG, a subsidiary of Ciba-Geigy: separate units were used for the red, green and blue images. In the 1990s, colour Eidophor projectors were used for large conference meetings and pop concerts.[br]Bibliography1946, "Views on the suitability of a cathode ray tube with a fluorescent screen for projection in cinemas", Bulletin of the Association of Swiss Electricians 39:468 (describes the concept of the Eidophor).Further ReadingE.H.Baumann, 1953, "The Fischer large screen projection system", Journal of Society of Motion Picture and Television Engineers 60:344.A.Robertson, 1976, "Projection television.
