1 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 -

4 Jenkins, Charles Francis
[br]b. 1867 USAd. 1934 USA[br]American pioneer of motion pictures and television.[br]During the early years of the motion picture industry, Jenkins made many innovations, including the development in 1894 of his own projector, the "Phantoscope", which was widely used for a number of years. In the same year he also suggested the possibility of electrically transmitting pictures over a distance, an interest that led to a lifetime of experimentation. As a result of his engineering contributions to the practical realization of moving pictures, in 1915 the National Motion Picture Board of Trade asked him to chair a committee charged with establishing technical standards for the industry. This in turn led to his proposing the creation of a professional society for those engineers in the industry, and the following year the Society of Motion Picture Engineers (later to become the Society of Motion Picture and Television Engineers) was formed, with Jenkins as its first President. Soon after this he began experiments with mechanical television, using both the Nipkow hole-spiral disc and a low-definition system of his own, based on rotating bevelled glass discs (his so-called "prismatic rings") and alkali-metal photocells. In the 1920s he gave many demonstrations of mechanical television, including a cable transmission of a crude silhouette of President Harding from Washington, DC, to Philadelphia in 1923 and a radio broadcast from Washington in 1928. The following year he formed the Jenkins Television Company to make television transmitters and receivers, but it soon went into debt and was acquired by the de Forest Company, from whom RCA later purchased the patents.[br]Principal Honours and DistinctionsFirst President, Society of Motion Picture Engineers 1916.Bibliography1923, "Radio photographs, radio movies and radio vision", Transactions of the Society of Motion Picture Engineers 16:78.1923, "Recent progress in the transmission of motion pictures by radio", Transactions ofthe Society of Motion Picture Engineers 17:81.1925, "Radio movies", Transactions of the Society of Motion Picture Engineers 21:7. 1930, "Television systems", Journal of the Society of Motion Picture Engineers 15:445. 1925.

5 Rosing, Boris
[br]fl. c. 1907 St Petersburg, Russia[br]Russian scientist who made early experiments in television.[br]In 1907, while Professor at St Petersburg Technological Institute, Rosing proposed the use of the Braun tube as a television display in conjunction with a photoelectric cell and double mirrordrum scanning system as a pick-up device. Four years later he was apparently able to transmit faint and very crude static pictures.[br]Bibliography1907, British patent no. 27,570.Further ReadingC.J.Hylander \& R Harding, 1941, An Introduction to Television.R.W.Hubbell, 1946, 4,000 Years of Television, London: G.Harrap \& Sons.See also: Baird, John Logie; Ives, Herbert Eugene; Jenkins, Charles Francis; Zworykin, Vladimir KosmaKF -
