Philo Farnsworth

Who was Philo Farnsworth?

Philo Taylor Farnsworth was an American inventor and television pioneer. He made many contributions that were crucial to the early development of all-electronic television. He is perhaps best known for inventing the first fully functional all-electronic image pickup device, the "image dissector", as well as the first fully functional and complete all-electronic television system. He was also the first person to demonstrate such a system to the public. Farnsworth developed a television system complete with receiver and camera, which he produced commercially in the firm of the Farnsworth Television and Radio Corporation, from 1938 to 1951.

In later life, Farnsworth invented a small nuclear fusion device, the Farnsworth–Hirsch fusor, or simply "fusor", employing inertial electrostatic confinement. Although not a practical device for generating nuclear energy, the fusor serves as a viable source of neutrons. The design of this device has been the acknowledged inspiration for other fusion approaches including the Polywell reactor concept in terms of a general approach to fusion design. Farnsworth held 165 patents, mostly in radio and television.
