Great inventions usually summon images of their brilliant creators. Eli Whitney and the cotton gin; Alexander Graham Bell and the telephone; Thomas Edison and the phonograph. But it is a peculiar fact that one of the inventions that has most influenced our daily lives for the past many decades is bereft of just such a heroic, technical visionary: the television. Schoolchildren aren’t told the odyssey of Philo T. Farnsworth, the Mormon farm boy from Iowa who used cathode ray tubes to invent an “image dissector” in the 1920s, or the tale of Russian immigrant Vladimir Zworykin, who worked with the Radio Corporation of America on similar techniques around the same time. Few people know that the first commercial television broadcast occurred at the 1939 World’s Fair in New York, where RCA unveiled its first television set.
