Discuss Article
Philo Farnsworth Philo Taylor Farnsworth (August 19 1906 - March 11 1971 ) was an American inventor of the vacuum tube television display, an idea he conceived at age 14 and developed at age 21.
Patent battles and the outbreak of World War II meant that he was never able to profit from his invention and he remains a forgotten figure overshadowed by inventors such as John Logie Baird who, unlike Farnsworth, did not invent a television system in use today.
The cathode ray tube developed from Farnsworth's work was used in all television sets until the late 20th century and the advent of plasma screens and other variants.
Farnsworth appears as a fictionalized character in Glen David Gold's novel Carter Beats the Devil (ISBN 0786886323).
