Philo Farnsworth
Philo Farnsworth spent much of his life as the most famous inventor nobody could name. On the 3rd of July 1957, he appeared on the CBS quiz show I've Got A Secret. He sat behind a curtain, billed only as the mystery guest, "Doctor X." A panel of celebrities questioned him and failed to guess his secret: he had invented electronic television. For stumping them, Farnsworth won eighty dollars and a carton of Winston cigarettes. It was an odd reward for the man behind a machine that was, by then, sitting in millions of American homes. He held the first patent the United States government ever granted for television. By the end of his life he held 300 patents in total. Even so, almost no one recognized his face or his name. How did a teenager from a farm in Idaho, with no formal engineering training, out-invent the country's best funded corporate laboratories? What happened in the legal fight that followed? Why did the inventor of television eventually walk away from the company built in his own name? And in his final years, why did his story bend not toward more recognition but toward a much harder, lonelier struggle? This is the story of Philo Farnsworth.
On the 19th of August 1906, Philo Taylor Farnsworth was born the eldest of five children of Lewis Edwin Farnsworth and Serena Amanda Bastian. The family lived in a small log cabin near Beaver, Utah, in a settlement called Manderfield, built years earlier by Lewis's own father. Philo's maternal grandfather, Jacob Bastian, had emigrated from Denmark as a Mormon convert, and the family followed the faith of the Church of Jesus Christ of Latter-day Saints.
In 1918, the Farnsworths moved to a relative's 240 acre ranch near Rigby, Idaho. Lewis supplemented the farm income by hauling freight with a horse-drawn wagon. Philo was thrilled to find their new home wired for electricity, powered by a Delco generator. He quickly became the household mechanic, fixing the troublesome generator and rewinding the armature of a burned-out motor he found discarded by earlier tenants. He converted his mother's hand-powered washing machine to run on electricity. A cache of old technology magazines in the attic, and his first telephone call to a distant relative, deepened his fascination. He even won $25 in a pulp-magazine contest for designing a magnetized car lock.
In the summer of 1921, not long before his fifteenth birthday, Farnsworth worked out the basic principle of what would become the image dissector. As a farm boy, his idea for scanning a picture as a series of lines came from watching the back-and-forth motion of plowing a field. At Rigby High School he excelled in chemistry and physics, and he asked his teacher, Justin Tolman, for advice about an electronic television system he was contemplating. He covered several blackboards with sketches and diagrams to show Tolman how it might work, and the teacher encouraged him to keep developing the idea.
In 1923 the family moved to Provo, Utah, and Farnsworth enrolled at Brigham Young High School. His father died of pneumonia in January 1924, at age 58, and Philo took on responsibility for supporting the family while finishing school. After graduating in June 1924, he applied to the United States Naval Academy in Annapolis and earned the nation's second-highest score on its recruiting tests. Realizing the government would own any patents he produced while in uniform, he secured an honorable discharge within months, using a provision that let the eldest child of a fatherless family be excused to support them.
Back in Provo, Farnsworth enrolled at Brigham Young University, where the faculty would not let him attend advanced science classes. He attended anyway and used the university's research laboratories without permission. He also earned a Junior Radio-Trician certification from the National Radio Institute, followed by full certification in 1925. While at college he met a Provo High School student, Elma "Pem" Gardner, who was born in 1908 and would later become his wife. His sister Agnes ran the family's boarding house while Philo worked, and the Farnsworths eventually shared a duplex with the Gardner family. He grew close to Pem's brother, Cliff Gardner, and the two moved to Salt Lake City to open a radio repair business together; it failed, and Gardner went home to Provo.
Farnsworth stayed on in Salt Lake City, where he met two San Francisco philanthropists, Leslie Gorrell and George Everson, then running a local fundraising campaign. They agreed to back his television research with an initial $6,000 and set him up with a laboratory in Los Angeles. He married Pem on the 27th of May 1926, and the couple traveled to Berkeley, California, by Pullman coach. From a rented house on Derby Street, he filed for his first television patent, which was granted on the 26th of August 1930. By then the Farnsworths had crossed the bay to San Francisco, where Philo opened a new laboratory at 202 Green Street. That address was about to become the site of the demonstration that made his career.
Most television systems of the late 1920s relied on a spinning Nipkow disk, a wheel punched with holes in a spiral pattern that swept across an image in short arcs, converting light into a flickering electrical signal. Farnsworth believed a fully electronic scanning system, with no moving mechanical parts, could produce a far sharper picture. Everson and Gorrell, backed by the advice of a nationally recognized patent attorney, urged him to patent every design as he went, a decision that would matter enormously in the fights ahead.
On the 7th of September 1927, Farnsworth's image dissector camera tube transmitted its first picture, a single straight line, to a receiver in another room of the Green Street laboratory. Pem Farnsworth recalled in 1984 that her husband broke the stunned silence of his lab assistants with the words, "There you are, electronic television!" The image had come from a glass slide lit from behind by an arc lamp, since the design's low light sensitivity demanded an unusually bright source.
By 1928 the system was polished enough for a demonstration to the press. Farnsworth's backers had been pressing him to know when they would see a financial return, so, fittingly, the very first image shown to reporters was a dollar sign. The following year, engineers eliminated a motor-generator from the design, leaving the television system with no mechanical parts whatsoever. That same year, Farnsworth transmitted the first live human images his system had ever captured, including a 3.5 inch picture of his wife Pem with her eyes closed, likely from the glare of the lighting required.
Other inventors had already built electromechanical television sets before him, but Farnsworth was the first to design and build a complete, all-electronic system, using electronic scanning in both the camera and the display. He first showed it to the press on the 3rd of September 1928, and to the wider public at the Franklin Institute in Philadelphia on the 25th of August 1934. Farnsworth had solved the technical problem. The much larger fight over who would get credit for it was only beginning.
In 1930, RCA hired Vladimir K. Zworykin, who had spent years since 1923 trying and failing to build his own all-electronic television at Westinghouse in Pittsburgh, to lead its new television division. Before leaving Westinghouse, Zworykin visited Farnsworth's laboratory and was impressed enough by the image dissector that his old team reportedly built several copies of it to study. He later abandoned the image dissector, which needed extremely bright lighting to work, and turned his energy toward what became RCA's Iconoscope. Decades later, in a videotaped interview from the 1970s, Zworykin admitted Farnsworth had used a cathode-ray tube for transmission before anyone else, adding only that Farnsworth "was very proud, and he stuck to his method."
Farnsworth's own patent filings told a more detailed story than Zworykin's account suggested. His patent for the image dissector, filed on the 26th of April 1933, described a charge storage plate, a concept credited to Kalman Tihanyi in 1928, along with a low-velocity scanning method and discrete particles whose electrical charge could be finely controlled. Two further patents, numbers 2,140,695 and 2,233,888, covered what he called a charge storage dissector and a charge storage amplifier.
In 1931, RCA's David Sarnoff offered Farnsworth $100,000 for his patents, on the condition that he become an RCA employee. Farnsworth refused. That June he instead joined the Philco company and moved to Philadelphia with his wife and two children. RCA responded by filing a patent interference suit, arguing that Zworykin's 1923 patent application predated Farnsworth's work, even though it could produce no evidence Zworykin had built a working transmitter tube before 1931. Farnsworth had already lost two smaller interference claims to Zworykin back in 1928, but this time, aided by his old teacher Justin Tolman's sketch of the blackboard drawing Farnsworth had shown him in the spring of 1922, he prevailed. The Patent Office ruled in his favor in 1934, and RCA's appeal failed in 1936. To keep funding the years of litigation that followed, Farnsworth was about to sail for England.
In 1932, while raising money in England for his ongoing legal battle, Farnsworth met John Logie Baird, the Scottish inventor who had staged the world's first public demonstration of television in London back in 1926 using a mechanical system. Baird, by then chasing electronic receivers of his own, demonstrated his mechanical setup for Farnsworth. In May 1933, Philco ended its relationship with him; Everson later explained that Farnsworth's drive to build a broad patent portfolio through research no longer matched Philco's push toward production, though he considered the split mutual and amicable. Farnsworth opened a new lab at 127 East Mermaid Lane in Philadelphia.
After sailing to Europe again in 1934, Farnsworth struck a licensing deal with the German firm Goerz-Bosch-Fernseh. Cameras built on his image dissector design were used to help broadcast the 1936 Olympic Games in Berlin. Back home, by 1936 his company was regularly transmitting experimental entertainment programs. That same year, working with biologists at the University of Pennsylvania, he developed a method for sterilizing milk using radio waves, and he separately invented a fog-penetrating beam meant for ships and airplanes.
In 1936, Collier's Weekly praised his work in glowing terms, calling him "a nineteen-year-old boy from Utah" whose electrically scanned television seemed destined to reach American homes, and noting that, barely thirty years old, he was "setting the specialized world of science on its ears." In 1938, Farnsworth founded the Farnsworth Television and Radio Corporation in Fort Wayne, Indiana, installing E. A. Nicholas as president while he himself served as director of research.
In September 1939, after more than a decade of legal combat, RCA finally agreed to a multi-year licensing deal covering Farnsworth's original 1927 television patent, worth $1 million in total. Having showcased electronic television at the New York World's Fair on the 20th of April 1939, RCA was now free to sell its own television cameras to the public. Farnsworth's own company, still bearing his name in Fort Wayne, would remain independent for just over a decade before a much larger corporation absorbed it.
In 1951, International Telephone and Telegraph, known as ITT, purchased the Farnsworth Television and Radio Corporation. Farnsworth spent his years there working out of a basement laboratory on Pontiac Street in Fort Wayne that staff nicknamed "the cave." From it came a string of breakthroughs, including a defense early warning signal, submarine detection devices, radar calibration equipment, and an infrared telescope. Art Resler, an ITT photographer who documented his work, later described him: "Philo was a very deep person, tough to engage in conversation, because he was always thinking about what he could do next." One of his most significant contributions there was the PPI Projector, an improvement on the circular-sweep radar display that made it possible to safely direct air traffic from the ground, and which became a forerunner of modern air traffic control.
ITT also agreed to nominally fund Farnsworth's real passion, nuclear fusion. He and his staff built and refined a series of devices called fusors, injecting high-temperature ions directly into a reaction chamber rather than slowly heating a magnetically confined plasma, which sidestepped a great deal of engineering complexity. For reasons neither Farnsworth nor his team ever pinned down, the resulting fusion reactions never lasted longer than thirty seconds. He patented the underlying methods anyway, including a device for producing interaction between nuclei and a system for electrostatic containment in fusion reactors. By the time he died he held 300 patents in the United States and abroad, work that fed into radar, infrared night-vision devices, the electron microscope, the baby incubator, the gastroscope, and the astronomical telescope.
In December 1965, ITT's board came under pressure to shut the costly fusion project down and sell off the Farnsworth subsidiary entirely. Only the urging of company president Harold Geneen kept it alive, with the 1966 budget approved to buy the research one more year. The stress of that ultimatum triggered a relapse in Farnsworth's health. A year later, ITT terminated him, and he was allowed to retire on medical grounds. Rather than let the work die, Farnsworth was about to gamble what remained of his family's security on keeping it going himself.
During that same 1957 appearance on I've Got A Secret, host Garry Moore spent several minutes questioning Farnsworth about his ongoing projects, including an early analog high-definition television system, flat-screen receivers, and fusion power. Farnsworth summed up his life's work simply: "My contribution was to take out the moving parts and make the thing entirely electronic." A letter later published in the Idaho Falls Post Register challenged the claim that this had been his only television appearance; a reader named Roy Southwick insisted he had interviewed Farnsworth back in 1953, on the first day the station KID-TV, later KIDK-TV, went on the air near Rigby.
In his later years, Farnsworth became dependent on alcohol. In 1967, he and his family moved back to Utah so he could continue his fusion research at Brigham Young University, which awarded him an honorary doctorate and offered him office space along with an underground concrete bunker. Certain ITT would dismantle its fusion lab, he invited several of his old staff to join him in a new venture, Philo T. Farnsworth Associates. By late 1968 the group was holding regular meetings and had landed a contract with NASA, but financing stalled well short of the $24,000 a month needed just for salaries and equipment rental.
In a 1996 videotaped interview for the Academy of Television Arts and Sciences, Pem recalled her husband's change of heart while they watched Neil Armstrong become the first person to walk on the Moon, on the 20th of July 1969. "When Neil Armstrong landed on the moon, Phil turned to me and said, 'Pem, this has made it all worthwhile,'" she remembered. "Before then, he wasn't too sure."
By Christmas 1970, the venture still had no financing, and the Farnsworths had sold their ITT stock and cashed in Philo's life insurance just to keep it afloat. The promised underwriter never came through, banks called in outstanding loans, repossession notices went up, and the Internal Revenue Service locked the laboratory door over unpaid taxes. The company folded in January 1971. Weeks later Farnsworth fell seriously ill with pneumonia and died on the 11th of March 1971, at age 64, at his home in Holladay, Utah, survived by his wife and their two sons.
Pem spent decades afterward fighting to secure her husband's place in history; he had always credited her equally, once saying, "my wife and I started this TV." She died on the 27th of April 2006, at age 98. In 1999, Time magazine had already named Farnsworth to its list of the hundred most important people of the twentieth century, a recognition that would eventually help put a statue of him inside the United States Capitol.
In 1984, Farnsworth was inducted into the National Inventors Hall of Fame. A bronze statue of him had represented the state of Utah inside the Capitol's National Statuary Hall since 1990, but on the 28th of January 2018, despite considerable public opposition, the Utah legislature voted to replace it with a statue of Martha Hughes Cannon. That replacement was finally unveiled in the Capitol's Emancipation Hall on the 11th of December 2024, standing alongside Utah's other statue, of Brigham Young. A separate statue of Farnsworth still stands inside the Utah State Capitol in Salt Lake City.
Other markers trace his path more directly. On the 15th of September 1981, California's state parks department placed a plaque honoring him as "The Genius of Green Street" outside his old San Francisco laboratory. In October 2008, the Letterman Digital Arts Center in San Francisco installed a statue of him sculpted by Lawrence Noble, and on the 10th of January 2011, Mayor Gavin Newsom inducted him into the city's newly created Hall of Fame. A 1983 United States postage stamp also carried his likeness.
Fort Wayne kept its own physical trace of him for decades. His basement laboratory, "the cave," survived until the old Farnsworth factory was demolished in 2010; that same year, the Fort Wayne History Center added factory artifacts to its collection, including a radio-phonograph and three table-top radios from the 1940s. His Fort Wayne home from 1948 to 1967 later became a television museum and was added to the National Register of Historic Places in 2013. Elsewhere in Indiana, a Farnsworth factory in Marion had built shortwave radios for American combat soldiers during the Second World War before RCA acquired it after the war ended.
His name lives on commercially and geographically as well: the streaming service Philo, headquartered in San Francisco, is named for him, as is Farnsworth Peak, a transmitter site roughly 18 miles southwest of Salt Lake City in the Oquirrh Mountains. Fiction has claimed him too. The absent-minded Professor Farnsworth on the animated series Futurama, which debuted in 1999, was named for him and later revealed to be his descendant, while playwright Aaron Sorkin dramatized his RCA battle in the 2007 stage play The Farnsworth Invention. In September 2025, host Nate Bargatze opened the 77th Primetime Emmy Awards with a comedy sketch playing Farnsworth himself, putting the inventor of television on the one stage his own machine ultimately made possible.
