Vladimir Kozmich Zworykin (Russian: ) (July 30, 1889 July 29, 1982) was a Russian-American inventor, engineer, and pioneer of television technology. Zworykin invented a television transmitting and receiving system employing cathode ray tubes. He played a role in the practical development of television from the early thirties, including charge storage-type tubes, infrared image tubes and the electron microscope. Zworykin''s reputation among biographers as the "true" inventor of television continues to slip, and in fact his last prominent supporter would seem to be Albert Abramson, who wrote the definitive biography on Zworykin in 1995.
