Philo Farnsworth

Vocation

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 (video camera tube), 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 (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 had begun abusing alcohol in his later years, and as a consequence he became seriously ill with pneumonia, and died on 11 March 1971. At the time he died, Farnsworth held 300 U.S. and foreign patents. His inventions contributed to the development of radar, infra-red night vision devices, the electron microscope, the baby incubator, the gastroscope, and the astronomical telescope.
