Farnsworth philosophy

Philo Farnsworth (August 19th 1906 close to Beaver in the Utah - March 11th 1971 with Salt Lake City) was a American inventor which contributed to the invention of the camera tube for the Télévision.

One generally allots to Vladimir Zworykin the paternity of the invention. If, in Russia, it had developed well the cathode-ray tube, it is Farnsworth which, the first, will show a complete television channel (send-receive).

Biography

Its family was member of the Église of Jesus-Christ of the Saints of the Last Days. The family moved towards Rigby (Idaho), where he worked as a sharecropper. Young Philosophy developed very early an interest for electronics after its first phone conversation and of discovered of a series of scientific magazines in the attic of the new house of the family.

After a short employment in the navy, Farnsworth is turned over to Idaho to help his/her mother. After its marriage with Elma “PEM” Gardner, it leaves to San Francisco. A local philanthropist finances his first experiments to him.

In 1926, Farnsworth formed an association with George Everson with Salt Lake City to develop its ideas of television. It settles with Los Angeles to carry out its research.

In 1927, the image image dissector tube transmitted its first image, a simple straight line. As of 1928, Farnsworth had sufficiently developed the system to make a public demonstration. As of 1929, the system was still improved; the system of television does not have now any more any mechanical moving part.

In 1930, Vladimir Zworykin, which had developed the tube with sweeping, visited his laboratory and was impressed by the invention and benefitted from it for espionner research from Farnsworth; the project of RCA always used a mechanical module of sweeping. As of its return to RCA, he worked to develop the device. In 1931, David Sarnoff of the RCA proposes to repurchase the patents of Farnsworth, but this one refused. He will make a lawsuit with RCA for plagiarism, but the enormous power of RCA and the quality of lawyers will make that the lawsuit will last of the years. In June of this year, Farnsworth joined the Philco company and moved its laboratory with Philadelphia.

The young person wire of Farnsworth, Kenny, dies in March 1932. Philco refuses in Farnsworth a leave so that it will bury his son. This episode will mortgage the marriage of Farnsworth and could marked the beginning of its depression. In 1934, Philco will cease its collaboration with him.

As of 1936, it will transmit regular programs of entertainment; the same year it will go to England and will form an alliance with John Logie Baird. Baird and Farnsworth competed with mechanical television to create the British standard of electronic television. As of 1939, the lawsuit finishes and Farnsworth will yield its patents to RCA against a sum raisonnable.
With the World Fair of New York, it is RCA which will be proposed like the creator of the télévision.
Farnsworth will begin the production of television sets then, but the production will stop with the entry in war of the the United States; Farnsworth will put its industry at the service of the production of the radars. Its patents will fall into the public domain in 1947, it will not have time to make fortune.

Farnsworth then knew a period of abuse, depression and alcoholism. As of 1949, it had ceased working on its projects bound on television.

Inventions

Tube television (Image image dissector tube)

Farnsworth developed the first vacuum tube for the catch of sight of television, an idea that it conceived at the 14 years age and that it developed with the 21 years age. It was the first step towards the electronic television which was going to supplant mechanical television. This invention was employed in all the television sets and other kinds of postings until the end of the 20th century when the technique of the sensors developed with CCC.

First engine with nuclear fusion

The Farnsworth-Hirsch Fusor , or simply the fusor, was the first nuclear experiment of Fusion towards the end of the year 1960.

Homage

It is almost certain that the professor Farnsworth of the televised series Futurama was named thus in his honor.

Media

A film of David Dugan of 1997, under the French title: Small screen, great invention! reports the life of the inventor.
