Vladimir Zworykin
Vladimir Zworykin (1888–1982) was a Russian-American inventor and engineer, best known for inventing a television transmission and receiver system using cathode ray tubes. In 1910, while at the St Peterburg Institute of Technology in Russia, he and his professor Boris Rosing developed his first television system. The transmitter used a mechanical scanner while the receiver was based on a cathode ray tube that had been invented by the German physicist Karl Braun (1850–1918).
Television system
Having emigrated to the United States in 1919, Zworykin joined the Westinghouse Electric Corporation in Pittsburgh the following year. Zworykin presented his project for an electronic television system to his employers in 1923, and worked on it through the 20s and 30s. In 1929 he invented the kinescope, or television receiver, an adaptation of Karl Braun's cathode ray tube. In 1933, he perfected the iconoscope, or video camera tube, a device which transmitted television images quickly and sharply.
These two inventions formed the first completely electronic television system. A German company, Telefunken, successfully used the iconoscope to broadcast the 1936 Berlin Olympic Games.
