Philo Farnsworth was born in 1906 August 19th and died in 1971 March 11 so he was 64 when he died. Philo Farnsworth is known as the man that was the inventor of the first electronic television, over 300 United States and foreign Patents. He made the world's first working television system with electronic scanning of both the pickup and display devices, which he first demonstrated to news media on September 1, 1928, televising a motion picture film.
In 1930, after a visit to Farnsworth's laboratory, Vladimir Zworykin copied this apparatus for RCA, though he found it impractical and returned to his work on the iconoscope. The U.S. Patent Office rendered a decision in 1935 that the "electrical image" of Farnsworth's image dissector was not in Zworykin's inventions, and priority of that invention was awarded to Farnsworth. In other words Zworykin did not get a reward for copying Farnsworth’s invention. On September 7, 1927, Farnsworth's Image dissector camera tube transmitted its first image, a simple straight line, at his laboratory at 202 Green Street in San Francisco. The source of the image was a glass slide, backlit by an arc lamp. This was due to the lack of light sensitivity of the Image Dissector tube design, a problem Farnsworth never managed to resolve independently. By 1928, Farnsworth had developed the system sufficiently to hold a demonstration for the press - 2 years after John Logie Baird had demonstrated his mechanical Television system in London. His backers had demanded to know when they would see dollars from the invention. The first image shown to them was a dollar sign. In 1929, the system was further improved by elimination of a motor generator the television system now had no mechanical moving parts. That year, Farnsworth transmitted the first live human images using his television system, including a three and a half-inch image of his wife, Pem (with her eyes closed because of the blinding light required). Farnsworth worked out the principle of the image dissector television camera at age 14, and produced the first working version at age 21. A farm boy, his inspiration for the scanning lines of the cathode ray tube (CRT) came from the back-and-forth motion used to plow a field. During a patent lawsuit against RCA in 1935, his high school chemistry teacher, Justin Tolman, reproduced a drawing that Farnsworth, when he was just 14, had made on the blackboard at the school. Farnsworth won the suit and was paid royalties but never became wealthy. The video camera tube developed from a combination of the work of Farnsworth and Zworykin, was used in all television cameras until the late 20th century, when alternate technologies such as charge-coupled devices started to appear.Farnsworth developed the "image oscillite", a cathode ray tube receiver that could display images captured by the image dissector. Farnsworth also invented the Farnsworth-Hirsch Fusor. Here are some pictures of Farnsworth’s inventions and him. I am now done!
