Editing Philo Farnsworth (section)

==TV appearance==
Although he was the man responsible for its technology, Farnsworth appeared only once on a television program. On July 3, 1957, he was a mystery guest ("Doctor X") on the CBS quiz show ''[[I've Got A Secret]]''. He fielded questions from the panel as they unsuccessfully tried to guess his secret ("I invented electronic television."). For stumping the panel, he received $80 and a carton of Winston cigarettes.<ref name="Schatzkin"/> Host [[Garry Moore]] then spent a few minutes discussing with Farnsworth his research on such projects as an early [[analog high-definition television system]], flat-screen receivers, and fusion power.<ref>{{youTube|pKM4MNrB25o|Philo Farnsworth on I've Got A Secret}}</ref> Farnsworth said, "There had been attempts to devise a television system using mechanical disks and rotating mirrors and vibrating mirrors—all mechanical. My contribution was to take out the moving parts and make the thing entirely electronic, and that was the concept that I had when I was just a freshman in high school in the Spring of 1921 at age 14."<ref name="EFarnsworth37">{{harvnb|Farnsworth|1990|page=37}}</ref>

A letter to the editor of the ''[[Idaho Falls Post Register]]'' disputed that Farnsworth had made only one television appearance. Roy Southwick claimed "... I interviewed Mr. [Philo] Farnsworth back in 1953—the first day [[KIDK-TV|KID-TV]] went on the air."<ref>Idaho Falls ''Post Register'', December 10, 2007, p.
