Philo Farnsworth

Philo Taylor Farnsworth (August 19, 1906 – March 11, 1971) was an American inventor credited with the invention of the cathode ray tube television.

Early life

Farnsworth 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.

Inventions

Television tube

Farnsworth 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.

Fusor

The 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 years

The 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.

Historian and author James W. Capitol building. It is also said that King's detractors in the Senate referred to him as "Miss Nancy." The theory is controversial and a source of debate among Buchanan and King historians. A statue of Farnsworth represents Utah in the U.S. Some historians have speculated that King may have been gay, and that he had a long-term intimate relationship with James Buchanan (it is not disputed that the two lived together for a time in Washington, DC).

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. He was interred in a vault on his plantation, and was later reinterred in Live Oak Cemetery, Selma, Dallas County, Alabama. It is said that Farnsworth’s genius was on the wane towards the end of his life due to alcoholism. King returned to his plantation, "King's Bend", Alabama, and died there. Nevertheless the fusor has since become a practical neutron source, and is produced commercially for this role. King's family estate. However, as with other fusion experiments, development into a power source has proven difficult. This has caused some backlash in the community due to allegations of significant financial liabilities for royalty fees now owed to Reverend Dr.

Hopes of the time were high that it could be quickly developed into a practical power source. King. 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. Martin Luther King, Jr." In May 2005, Washington State Governer Christine Gregoire signed legislation formalizing the prior resolution officially designating King County's name to be in honor of Reverend Dr. 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. King County still exists, but the county council in 1986 passed a resolution "setting forth the historical basis for the 'renaming' of King County in honor of Reverend Dr. The Farnsworth-Hirsch Fusor, or simply fusor, is an apparatus designed by Farnsworth to create nuclear fusion. In honor of his inauguration, the newly formed Washington Territory named King County for him, as well as Pierce County after President Pierce, in hopes of gaining speedy admission to the Union by currying favor with the new administration (Washington did not become a state until 1889).

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 of the United States on the Democratic ticket with Franklin Pierce in 1852 and took the oath of office March 4, 1853, in Cuba, where he had gone for his health, which was a privilege extended by special act of Congress. 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 served as President pro tempore of the Senate during the Thirty-first and Thirty-second Congresses and was Chairman of the Committee on Foreign Relations and Committee on Pensions. Farnsworth won the suit and was paid royalties but never became wealthy. Bagby and served from July 1, 1848 until his resignation on December 20, 1852 due to poor health. During a patent lawsuit against RCA his high school teacher redrew a drawing Farnsworth had made on the blackboard when he was 14. He was appointed and subsequently elected as a Democrat to the Senate to fill the vacancy caused by the resignation of Arthur P.

Farnsworth developed the vacuum tube television display, an idea he conceived at age 14 and developed at age 21. He was Minister to France from 1844 to 1846. By 1949 he had ceased working on television-related projects. King was Chairman of the Committee on Public Lands and the Committee on Commerce. Farnsworth then entered a period of chronic alcohol abuse, depression and dependencies on drugs. He served as President pro tempore of the United States Senate during the Twenty-fourth through Twenty-seventh Congresses. By 1939 Farnsworth’s company had licenced patents to RCA. Upon the admission of Alabama as a State in 1819 he was elected as a Democratic-Republican to the United States Senate, and was reelected as a Jacksonian in 1822, 1828, 1834, and 1841, serving from December 14, 1819, until April 15, 1844, when he resigned.

Baird and Farnsworth competed with EMI for forming the standard UK television system. King was a delegate to the convention which organized the State government. By 1936 Farnsworth’s company was transmitting regular entertainment programs; that year he travelled to England and formed an alliance with John Logie Baird. He returned to the United States in 1818 and located in Cahawba, Alabama, where he became a planter. Since RCA controlled key patents and manufacture of radio tubes, Philco was persuaded to sever its relationship with Farnsworth in 1934. King was secretary of the legation at Naples and later at Saint Petersburg. 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. He was a member of the State House of Commons from 1807 to 1809, city solicitor of Wilmington, North Carolina in 1810, and elected to the Twelfth, Thirteenth, and Fourteenth Congresses, serving from March 4, 1811 until November 4, 1816, when he resigned.

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. He was admitted to the bar in 1806 and began practice in Clinton, North Carolina. 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. King was born in Sampson County, North Carolina, and graduated from the University of North Carolina in 1803. In 1929 the system was further improved by elimination of a motor generator; the television system now had no mechanical moving parts. He was the shortest-serving person to occupy that office without becoming President (John Tyler was the shortest-serving, with Andrew Johnson also serving less time than King). By 1928 Farnsworth had developed the system sufficiently to hold a demonstration for the press. Representative from North Carolina, a Senator from Alabama, and the thirteenth Vice President of the United States.

In 1927 Farnsworth’s Image Dissector camera tube transmitted its first image, a simple straight line.
