Philo Taylor Farnsworth

Farnsworth, Philo Taylor (1906–71), U.S. radio research engineer who pioneered television technology. As a teenager, Farnsworth developed an electronic television system superior to the mechanical discs in limited use at the time. In 1927 Farnsworth publicly demonstrated his electronic television tube, an image dissector that created an image by producing an electronic signal that matched the brightness of the object being televised. By 1939 the Radio Corporation of America (RCA) obtained a license from Farnsworth to use his technology along with their own.
