Philo FarnsworthPhilo Taylor Farnsworth (August 19, 1906 – March 11, 1971) was an American inventor credited with the invention of the cathode ray tube television. Philo T. Farnsworth with his television tubeEarly lifeFarnsworth was born in Indian Springs, Utah on August 19, 1906. His family were members of The Church of Jesus Christ of Latter-day Saints. His father later moved the family to Rigby, Idaho, where he worked as a sharecropper. Young Philo developed an early interest in electronics after his first telephone conversation with an out-of-state relative and the discovery of a large cache of technology magazines in the attic of the family’s new home. After a brief stint in the Navy, Farnsworth returned to Idaho to help support his mother. He later moved to the San Francisco Bay area with his bride, Elma “Pem” Gardner-Farnsworth. A local philanthropist managing a community chest agreed to fund Farnsworth’s early television experiments (see below). In 1926, Farnsworth formed a partnership with George Everson in Salt Lake City to develop Farnsworth’s television ideas. He moved to Los Angeles to carry out research. In 1927 Farnsworth’s Image Dissector camera tube transmitted its first image, a simple straight line. By 1928 Farnsworth had developed the system sufficiently to hold a demonstration for the press. In 1929 the system was further improved by elimination of a motor generator; the television system now had no mechanical moving parts. In 1930 Vladimir Zworykin visited the laboratory and was impressed with the performance of the camera tube; the RCA project at the time still used a mechanical scanner. In 1931 David Sarnoff of RCA offered to buy Farnsworth’s patents but was refused; in June of that year Farnsworth joined the Philco company and moved his laboratory to Philadelphia, along with his wife and two children. Philco denied Farnsworth time to travel to Utah to bury his young son Kenny, who died in March 1932; this death put a strain on Farnsworth’s marriage and may have marked the beginning of his struggle with depression. Since RCA controlled key patents and manufacture of radio tubes, Philco was persuaded to sever its relationship with Farnsworth in 1934. By 1936 Farnsworth’s company was transmitting regular entertainment programs; that year he travelled to England and formed an alliance with John Logie Baird. Baird and Farnsworth competed with EMI for forming the standard UK television system. By 1939 Farnsworth’s company had licenced patents to RCA. Farnsworth then entered a period of chronic alcohol abuse, depression and dependencies on drugs. By 1949 he had ceased working on television-related projects. InventionsTelevision tubeFarnsworth developed the vacuum tube television display, an idea he conceived at age 14 and developed at age 21. During a patent lawsuit against RCA his high school teacher redrew a drawing Farnsworth had made on the blackboard when he was 14. Farnsworth won the suit and was paid royalties but never became wealthy. The cathode ray tube configuration developed from Farnsworth’s work was used in all television sets and other kinds of displays until the late 20th century when a small portion of televisions were made with alternate technologies such as liquid crystal displays. Farnsworth developed the Image Dissector, a practical all-electronic image scanning device that made it possible to dispense with the moving parts of mechanical television. FusorThe Farnsworth-Hirsch Fusor, or simply fusor, is an apparatus designed by Farnsworth to create nuclear fusion. Unlike most controlled fusion systems, which slowly heat a magnetically confined plasma, the fusor injects high temperature ions directly into a reaction chamber, thereby avoiding a considerable amount of complexity. When Farnsworth-Hirsch Fusor was first introduced to the fusion research world in the late 1960s, the Fusor was the first device that could clearly demonstrate it was producing any fusion reactions at all. Hopes of the time were high that it could be quickly developed into a practical power source. However, as with other fusion experiments, development into a power source has proven difficult. Nevertheless the fusor has since become a practical neutron source, and is produced commercially for this role. Later yearsThe plaque on Green Street.It is said that Farnsworth’s genius was on the wane towards the end of his life due to alcoholism. A plaque honoring Farnsworth as The Genius of Green Street is located on the 202 Green Street location of his research laboratory in San Francisco. A statue of Farnsworth represents Utah in the U.S. Capitol building. A movie dramatization of Farnsworth’s life and work is currently under production. The film is being written by West Wing director Aaron Sorkin. Patents

A plaque honoring Farnsworth as The Genius of Green Street is located on the 202 Green Street location of his research laboratory in San Francisco. Tompkins was the first Vice President actually on a ticket after the passage of the Twelfth Amendment, as opposed to being named Vice President for being the Presidential election's runner-up (as with the first four Vice Presidents) or being appointed by a sitting president (as with Elbridge Gerry). It is said that Farnsworth’s genius was on the wane towards the end of his life due to alcoholism. However, others believe that he added the middle initial "D" (which stood for nothing) while a student at Columbia College, to distinguish himself from another Daniel Tompkins there. Nevertheless the fusor has since become a practical neutron source, and is produced commercially for this role. There is evidence that Daniel Tompkins's middle name was Decius. However, as with other fusion experiments, development into a power source has proven difficult. Mark's Churchyard, New York City. Hopes of the time were high that it could be quickly developed into a practical power source. He died in Tompkinsville, three months after retiring as Vice President, and was interred in the Minthorne vault in St. When Farnsworth-Hirsch Fusor was first introduced to the fusion research world in the late 1960s, the Fusor was the first device that could clearly demonstrate it was producing any fusion reactions at all. He was a delegate to the state constitutional convention in 1821, serving as its president. Unlike most controlled fusion systems, which slowly heat a magnetically confined plasma, the fusor injects high temperature ions directly into a reaction chamber, thereby avoiding a considerable amount of complexity. In 1817 he built a dock along the waterfront in the neighborhood and began offering daily steam ferry service between Staten Island and Manhattan. The Farnsworth-Hirsch Fusor, or simply fusor, is an apparatus designed by Farnsworth to create nuclear fusion. In 1815 Tompkins established a settlement and along the eastern shore of Staten Island that came to be called Tompkinsville. Farnsworth developed the Image Dissector, a practical all-electronic image scanning device that made it possible to dispense with the moving parts of mechanical television. He was elected Vice President on the ticket with James Monroe in 1816, and was reelected in 1820, serving from March 4, 1817 to March 4, 1825. The cathode ray tube configuration developed from Farnsworth’s work was used in all television sets and other kinds of displays until the late 20th century when a small portion of televisions were made with alternate technologies such as liquid crystal displays. He declined an appointment as United States Secretary of State by President James Madison. Farnsworth won the suit and was paid royalties but never became wealthy. He was Governor of New York from 1807 to 1817. During a patent lawsuit against RCA his high school teacher redrew a drawing Farnsworth had made on the blackboard when he was 14. Tompkins was a delegate to the state constitutional convention in 1801, a member of the state Assembly in 1803, and was elected to the United States Congress, but resigned before the beginning of the term to accept an appointment as associate justice of the state supreme court, in which capacity he served from 1804 to 1807. Farnsworth developed the vacuum tube television display, an idea he conceived at age 14 and developed at age 21. He studied law, and was admitted to the bar in 1797, practicing in New York City;. By 1949 he had ceased working on television-related projects. He graduated from Columbia College in New York City, in 1795. Farnsworth then entered a period of chronic alcohol abuse, depression and dependencies on drugs. He was born in Fox Meadows (later Scarsdale), Westchester County, New York. By 1939 Farnsworth’s company had licenced patents to RCA. Daniel D[ecius?] Tompkins (June 21, 1774 – June 11, 1825) was an entrepreneur, jurist, Congressman, Governor of New York, and the sixth Vice President of the United States.
