Vladimir Zworykin was a Russian-American engineer at RCA who filed a patent application for an electronic camera tube concept, the iconoscope, in 1923, and led RCA's development of a working electronic television system in the early 1930s. RCA's attempt to claim priority over Philo Farnsworth on the strength of the unreduced 1923 filing failed in a 1934 patent office ruling.
