Zworykin holding an iconoscope, an early television camera tube. Vladimir Kosmich Zworykin (July 29, 1888 - July 29, 1982) was a Russian-American inventor, engineer, and pioneer of television technology. In 1919, he emigrated to the United States to work at the Westinghouse laboratory in Pittsburgh. In 1929, he invented the cathode-ray tube called the kinescope and was one of the first to demonstrate a television system with all the features of modern picture tubes. Having developed the prototype of the receiver by December, Zworykin met David Sarnoff, who hired him and put him in charge of television development for RCA at their newly established laboratories in Camden, New Jersey. In 1931 he invented a new type of cathode ray transmitter, that he named Iconoscope, which became the leading camera tube used for TV broadcasting. In 1935, the Iconoscope, was introduced in Germany. It was soon developed there, with some improvements, and was successfully used at the 1936 Berlin Olympic Games as one of several cameras. Zworykin retired in 1954 and died in 1982 at the age of 94.
