Philo Taylor Farnsworth (August 19, 1906 – March 11, 1971) was an American inventor and television pioneer.[2][3] He made the critical contributions to electronic television that made possible all the video in the world today.[4] He is best known for his 1927 invention of 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.[5][6] Farnsworth developed a television system complete with receiver and camera—which he produced commercially through the Farnsworth Television and Radio Corporation from 1938 to 1951, in Fort Wayne, Indiana.[7][8]

In later life, Farnsworth invented a small nuclear fusion device, the Farnsworth Fusor, employing inertial electrostatic confinement (IEC). Like many fusion devices, it was not a practical device for generating nuclear power, although it provides a viable source of neutrons.[9] The design of this device has been the inspiration for other fusion approaches, including the Polywell reactor concept.[10] Farnsworth held 300 patents, mostly in radio and television.

Early life

Farnsworth was born August 19, 1906, the eldest of five children

armature; he converted his mother's hand-powered washing machine into an electric-powered one.[13] He developed an early interest in electronics after his first telephone conversation with a distant relative, and he discovered a large cache of technology magazines in the attic of their new home.[14] He won $25 in a pulp-magazine contest for inventing a magnetized car lock.[11] Farnsworth was a member of the Church of Jesus Christ of Latter-day Saints.[15][16]

Farnsworth excelled in chemistry and physics at Rigby High School. He asked science teacher Justin Tolman for advice about an electronic television system that he was contemplating; he provided the teacher with sketches and diagrams covering several blackboards to show how it might be accomplished electronically, and Tolman encouraged him to develop his ideas.[17] One of the drawings that he did on a blackboard for his chemistry teacher was recalled and reproduced for a patent interference case between Farnsworth and RCA.[18]

In 1923, the family moved to

Annapolis, Maryland, where he earned the nation's second-highest score on academy recruiting tests.[14] However, he was already thinking ahead to his television projects; he learned that the government would own his patents if he stayed in the military, so he obtained an honorable discharge within months of joining[14] under a provision in which the eldest child in a fatherless family could be excused from military service to provide for his family. He returned to Provo and enrolled at Brigham Young University, but he was not allowed by the faculty to attend their advanced science classes based upon policy considerations.[12] He attended anyway and made use of the university's research labs, and he earned a Junior Radio-Trician certification from the National Radio Institute, and full certification in 1925.[12] While attending college, he met Provo High School student Elma "Pem" Gardner[12] (1908–2006),[19]
whom he eventually married.

Farnsworth worked while his sister Agnes took charge of the family home and the second-floor boarding house, with the help of a cousin living with the family. The Farnsworths later moved into half of a duplex, with family friends the Gardners moving into the other side when it became vacant.[20] He developed a close friendship with Pem's brother Cliff Gardner, who shared his interest in electronics, and the two moved to Salt Lake City to start a radio repair business.[14] The business failed, and Gardner returned to Provo.[citation needed]

Farnsworth remained in Salt Lake City and became acquainted with Leslie Gorrell and George Everson, a pair of San Francisco philanthropists who were then conducting a Salt Lake City Community Chest fund-raising campaign.[21][22] They agreed to fund his early television research with an initial $6,000 in backing,[23] and set up a laboratory in Los Angeles for Farnsworth to carry out his experiments.[24]

Farnsworth married Pem[19] on May 27, 1926,[12] and the two traveled to Berkeley, California, in a Pullman coach. They rented a house at 2910 Derby Street, from which he applied for his first television patent, which was granted on August 26, 1930.[14] By that time they had moved across the bay to San Francisco, where Farnsworth set up his new lab at 202 Green Street.[25]

Career

A few months after arriving in California, Farnsworth was prepared to show his models and drawings to a patent attorney who was nationally recognized as an authority on electrophysics. Everson and Gorrell agreed that Farnsworth should apply for patents for his designs, a decision that proved crucial in later disputes with RCA.[26] Most television systems in use at the time used image scanning devices ("rasterizers") employing rotating "Nipkow disks" comprising a spinning disk with holes arranged in spiral patterns such that they swept across an image in a succession of short arcs while focusing the light they captured on photosensitive elements, thus producing a varying electrical signal corresponding to the variations in light intensity. Farnsworth recognized the limitations of the mechanical systems, and that an all-electronic scanning system could produce a superior image for transmission to a receiving device.[26][13]

On September 7, 1927, Farnsworth's

motor-generator, which meant the television system now had no mechanical 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.[citation needed
]

Many inventors had built electromechanical television systems before Farnsworth's seminal contribution, but Farnsworth designed and built the world's first working all-electronic television system, employing electronic scanning in both the pickup and display devices. He first demonstrated his system to the press on September 3, 1928,[25][28] and to the public at the Franklin Institute in Philadelphia on August 25, 1934.[29]

In 1930, RCA recruited

Westinghouse in Pittsburgh since 1923[30]—to lead its television development department. Before leaving his old employer, Zworykin visited Farnsworth's laboratory, and was sufficiently impressed with the performance of the Image Dissector that he reportedly had his team at Westinghouse make several copies of the device for experimentation.[31] Zworykin later abandoned research on the Image Dissector, which at the time required extremely bright illumination of its subjects, and turned his attention to what became the Iconoscope.[32] In a 1970s series of videotaped interviews, Zworykin recalled that, "Farnsworth was closer to this thing you're using now [i.e., a video camera] than anybody, because he used the cathode-ray tube for transmission. But, Farnsworth didn't have the mosaic [of discrete light elements], he didn't have storage. Therefore, [picture] definition was very low.... But he was very proud, and he stuck to his method."[33] Contrary to Zworykin's statement, Farnsworth's patent number 2,087,683 for the Image Dissector (filed April 26, 1933) features the "charge storage plate" invented by Tihanyi in 1928 and a "low velocity" method of electron scanning, also describes "discrete particles" whose "potential" is manipulated and "saturated" to varying degrees depending on their velocity.[34]
Farnsworth's patent numbers 2,140,695 and 2,233,888 are for a "charge storage dissector" and "charge storage amplifier," respectively.

In 1931,

U.S. Patent Office rendered a decision in 1934 awarding priority of the invention of the image dissector to Farnsworth. RCA lost a subsequent appeal, but litigation over a variety of issues continued for several years before Sarnoff finally agreed to pay Farnsworth royalties.[36][37]

In 1932, while in England to raise money for his legal battles with RCA, Farnsworth met with John Logie Baird, a Scottish inventor who had given the world's first public demonstration of a working television system in London in 1926, using an electro-mechanical imaging system, and who was seeking to develop electronic television receivers. Baird demonstrated his mechanical system for Farnsworth.[38]

In May 1933, Philco severed its relationship with Farnsworth because, said Everson, "it [had] become apparent that Philo's aim at establishing a broad patent structure through research [was] not identical with the production program of Philco."[39] In Everson's view the decision was mutual and amicable.[40] Farnsworth set up shop at 127 East Mermaid Lane in Philadelphia, and in 1934 held the first public exhibition of his device at the Franklin Institute in that city.[41]

After sailing to Europe in 1934, Farnsworth secured an agreement with Goerz-Bosch-Fernseh in Germany.[26] Some image dissector cameras were used to broadcast the 1936 Olympic Games in Berlin.[42]

Farnsworth returned to his laboratory, and by 1936 his company was regularly transmitting entertainment programs on an experimental basis.[43] That same year, while working with University of Pennsylvania biologists, Farnsworth developed a process to sterilize milk using radio waves.[1] He also invented a fog-penetrating beam for ships and airplanes.[26]

In 1936, he attracted the attention of

Collier's Weekly, which described his work in glowing terms. "One of those amazing facts of modern life that just don't seem possible—namely, electrically scanned television that seems destined to reach your home next year, was largely given to the world by a nineteen-year-old boy from Utah ... Today, barely thirty years old he is setting the specialized world of science on its ears."[citation needed
]

In 1938, Farnsworth established the Farnsworth Television and Radio Corporation in Fort Wayne, Indiana, with E. A. Nicholas as president and himself as director of research.[7] In September 1939, after a more than decade-long legal battle, RCA finally conceded to a multi-year licensing agreement concerning Farnsworth's 1927 patent for television totaling $1 million. RCA was then free, after showcasing electronic television at New York World's Fair on April 20, 1939, to sell electronic television cameras to the public.[7][29]: 250–254 

Farnsworth Television and Radio Corporation was purchased by

PPI Projector, an enhancement on the iconic "circular sweep" radar display, which allowed safe air traffic control from the ground. This system developed in the 1950s was the forerunner of today's air traffic control systems.[1]

In addition to his electronics research, ITT management agreed to nominally fund Farnsworth's nuclear fusion research. He and staff members invented and refined a series of fusion reaction tubes called "fusors". For scientific reasons unknown to Farnsworth and his staff, the necessary reactions lasted no longer than thirty seconds. In December 1965, ITT came under pressure from its board of directors to terminate the expensive project and sell the Farnsworth subsidiary. It was only due to the urging of president Harold Geneen that the 1966 budget was accepted, extending ITT's fusion research for an additional year. The stress associated with this managerial ultimatum, however, caused Farnsworth to suffer a relapse. A year later he was terminated and eventually allowed medical retirement.[44]

In 1967, Farnsworth and his family moved back to Utah to continue his fusion research at

Salt Lake City, as team members in Philo T. Farnsworth Associates (PTFA). By late 1968, the associates began holding regular business meetings and PTFA was underway. They promptly secured a contract with the National Aeronautics and Space Administration (NASA), and more possibilities were within reach—but financing stalled for the $24,000 a month required for salaries and equipment rental.[44]

In a 1996 videotaped interview by the Academy of Television Arts & Sciences, Farnsworth's wife recounted his change of heart about the value of television, after seeing Neil Armstrong becoming the first person to walk on the Moon in real time on July 20, 1969, along with millions of others:[45] "We were watching it, and, when Neil Armstrong landed on the moon, Phil turned to me and said, 'Pem, this has made it all worthwhile.' Before then, he wasn't too sure."

By

underwriter had failed to provide the financial backing that was to have supported the organization during its critical first year. The banks called in all outstanding loans, repossession notices were placed on anything not previously sold, and the Internal Revenue Service
put a lock on the laboratory door until delinquent taxes were paid. In January 1971, PTFA disbanded.

Farnsworth had begun abusing alcohol in his later years,[46] and as a result became seriously ill with pneumonia, and died on March 11, 1971, at his home in Holladay, Utah.[44][47]

Farnsworth's wife Elma Gardner "Pem" Farnsworth fought for decades after his death to assure his place in history. Farnsworth always gave her equal credit for creating television, saying, "my wife and I started this TV." She died on April 27, 2006, at age 98.[48] The inventor and wife were survived by two sons, Russell (then living in New York City), and Kent (then living in Fort Wayne, Indiana).[48]

In 1999, Time magazine included Farnsworth in the "Time 100: The Most Important People of the Century".[36]

Inventions

Electronic TV

Farnsworth worked out the principle of the image dissector in the summer of 1921, not long before his 15th birthday, and demonstrated the first working version on September 7, 1927, having turned 21 the previous August. A farm boy, his inspiration for scanning an image as a series of lines came from the back-and-forth motion used to plow a field.

Radio Corporation of America in 1934 and decided in February 1935, his high school chemistry teacher, Justin Tolman, produced a sketch he had made of a blackboard drawing Farnsworth had shown him in spring 1922. Farnsworth won the suit; RCA appealed the decision in 1936 and lost.[13] Farnsworth received royalties from RCA, but he never became wealthy. The video camera tube that evolved from the combined work of Farnsworth, Zworykin, and many others was used in all television cameras until the late 20th century, when alternate technologies such as charge-coupled devices began to appear.[citation needed
]

Farnsworth also developed the "image oscillite", a cathode ray tube that displayed the images captured by the image dissector.[13]

Farnsworth called his device an image dissector because it converted individual elements of the image into electricity one at a time. He replaced the spinning disks with cesium, an element that emits electrons when exposed to light.[citation needed]

In 1984, Farnsworth was inducted into the National Inventors Hall of Fame.[citation needed]

Fusor

The Farnsworth 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.[citation needed]

When the Farnsworth 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 fusion reactions at all. Hopes at 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.[9][49]

Other inventions

At the time he died, Farnsworth held 300 U.S. and foreign

gastroscope, and the astronomical telescope.[44][50]

TV appearance

Although he was the man responsible for its technology, Farnsworth appeared only once on a television program. On July 3, 1957, he was a mystery guest ("Doctor X") on the CBS quiz show

I've Got A Secret. He fielded questions from the panel as they unsuccessfully tried to guess his secret ("I invented electronic television."). For stumping the panel, he received $80 and a carton of Winston cigarettes.[21] Host Garry Moore then spent a few minutes discussing with Farnsworth his research on such projects as an early analog high-definition television system, flat-screen receivers, and fusion power.[51] Farnsworth said, "There had been attempts to devise a television system using mechanical disks and rotating mirrors and vibrating mirrors—all mechanical. My contribution was to take out the moving parts and make the thing entirely electronic, and that was the concept that I had when I was just a freshman in high school in the Spring of 1921 at age 14."[52]

A letter to the editor of the

KID-TV went on the air."[53] KID-TV, which later became KIDK-TV, was then located near the Rigby area where Farnsworth grew up.[citation needed

Fort Wayne sites

Farnsworth's house in Fort Wayne

In 2010, the former Farnsworth factory in Fort Wayne, Indiana, was razed,[87] eliminating the "cave," where many of Farnsworth's inventions were first created, and where its radio and television receivers and transmitters, television tubes, and radio-phonographs were mass-produced under the Farnsworth, Capehart, and Panamuse trade names.[88] The facility was located at 3702 E. Pontiac St.[88]

Also that year, additional Farnsworth factory artifacts were added to the Fort Wayne History Center's collection, including a radio-phonograph and three table-top radios from the 1940s, as well as advertising and product materials from the 1930s to the 1950s.[89]

Farnsworth's Fort Wayne residence from 1948 to 1967, then the former Philo T. Farnsworth Television Museum, stands at 734 E. State Blvd, on the southwest corner of E. State and St. Joseph Blvds. The residence is recognized by an Indiana state historical marker and was listed on the National Register of Historic Places in 2013.[90][91]

Marion, Indiana factory

In addition to Fort Wayne, Farnsworth operated a factory in Marion, Indiana, that made shortwave radios used by American combat soldiers in World War II.[92] Acquired by RCA after the war, the facility was located at 3301 S. Adams St.[93]
