While it was Scottish inventor John Logie Baird who had given the world’s first public demonstration of a working television system in London in 1926, using an electro-mechanical imaging system, and who was seeking to develop electronic television receivers, it was Utah inventor Philo T. Farnsworth ( https://en.wikipedia.org/wiki/Philo_Farnsworth ) who succeeded in 1927 with the “first fully functional all-electronic image pickup device (video camera tube), the ‘image dissector,’ as well as the first fully functional and complete all-electronic television system[.]”
I guess it depends on how one sees the invention of the television or the invention of the “kind” of television still used today ... to determine which of the two men was the inventor.
I got to live for a few years in the house that was once the residence of Farnsworth. While I and the current owner searched and searched, we found no evidence of Farnsworth’s invention in the house. Too bad, but it did get me interested in his life.
I learned that Farnsworth ended up hating his invention because he saw it being used to brain-wash the public.
