Farnsworth, Philo, FY loh, Taylor (1906-1971), an American inventor, was a pioneer in television technology. While still a teen-ager, he created an electronic television system that was superior to the mechanical discs used experimentally at the time. At the age of 20, Farnsworth applied for a patent for an electronic television camera tube that became known as an image dissector. It created an image by producing an electronic signal that corresponded to the brightness of the objects being televised. Farnsworth demonstrated the image dissector in 1927.
