Philo Taylor Farnsworth
(August 19, 1906 â€“ October 2, 1971)
was an American inventor and television pioneer. Although 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 (video camera tube), the "image dissector", the first fully functional and complete all-electronic television system, and for being 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 Farnsworthâ€“Hirsch fusor, or simply "fusor", employing inertial electrostatic confinement (IEC). 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.
