Philo T Farnsworth displays his television receptor for the press,
|
Inventor Philo T. Farnsworth was born in a log cabin on his grandfather’s remote
ranch in southwest Utah on August 19, 1906. His
family was of pioneer Mormon stock.
Despite the classic 19th Century
pioneer circumstances of his birth, Farnsworth would help reshape the modern
world with his inventions.
By 1918 the family was ranching on
its own in southern Idaho. The
new homestead had its own small generator
and was primitively wired for lighting
and some farm equipment. Young
Philo, a tinkerer in the great
tradition and a devotee of Popular Mechanics was soon busy
adapting other gadgets and appliances to being run by electricity.
He proved to be a whiz in high school in Rigby, Idaho at advanced
math, chemistry, and physics.
But he stunned Justin Tolman,
his high school science teacher, with sketches for electron tubes. He demonstrated how pictures might be transmitted
and received wirelessly over a
distance by filling several chalkboards
with equations for his awestruck
teacher. That teacher’s memory of these early events later became key testimony in Farnsworth’s epic patent battles with the Radio
Corporation of America (RCA).
Farnsworth's high school science teacher Justin Tomlin saved his sketch of an electron tube which eventually proved the inventor's priority over competitors.

After graduating from high school
early, Farnsworth worked for the railroad
to raise money for tuition to Brigham
Young University. In 1923 he joined his family, which had moved to Provo, Utah. But when his father died less than a year later, 16
year old Philo was forced to quit school to support his family.
But his dreams never died. He
seized another opportunity to get a quality education when he tested number 2
in the nation and was recruited to the U.S.
Naval Academy. But when he discovered that the Navy would own any patents he developed during his
continuing research, he resigned and returned to Utah.
An unsuccessful business venture brought him to Salt Lake City, where he took classes at the University of Utah. He also caught the eye of George Everson, a professional fund raiser and philanthropist to work with local Community Chest. Philo’s project so excited him that he
agreed to pay for him to move to Los
Angeles where he would be provided housing and a small laboratory space.

Farnsworth leapt at the opportunity.
He married his sweetheart, Elma “Pem” Gardner, the sister of an
associate of Everson.
After a period in L.A., the
Farnsworth’s moved to San Francisco to
be closer to Everson. Despite Everson’s support, it was difficult to keep
up the research and support the family. Farnsworth worked mostly alone
and the strange looking apparatus
that were brought into his apartment/laboratory aroused suspicion and the place
was raided by local police suspecting he was running a distillery.
After only a few months in
California, however, Farnsworth was far enough along in his work to file
patents. Others were developing television
systems, based on mechanical
scanning devices. Farnsworth proposed an entirely electronic system to produce images that could be received
on another devise. These early patent applications gave him a lead over
others who were experimenting with electronic systems.
In September, 1927 Farnsworth
transmitted his first image in his San Francisco lab, a simple line inscribed on a black plate back illuminated by a
powerful arc lamp to a receiving
device which reproduced the image by an electronic
scan. He demonstrated his
device to the press a year later.
In 1930 Farnsworth’s patents were
approved. He was also visited by Vladimir
Zworykin, who had been developing his own television system in Pittsburg for Westinghouse for some years. Although his system was
promising, it never functioned well enough. Impressed, he made copies of
Farnsworth’s Image Dissector for his
own use. He would eventually abandon that technique because of the
extremely bright lighting required and turn his attention to developing the Iconoscope.

Meanwhile Farnsworth turned down an
offer by David Sarnoff of RCA to buy his patents and work for
them. Again the inventor balked at having his patents held by
others. Instead he moved to Philadelphia
where he found what he hoped would be a congenial home at Philco.
RCA acquired Zworykin’s patents,
which Zworykin had already used to challenge Farnsworth’s. The
company renewed the objections, but in 1934, based on evidence from that high
school teacher and others, the Patent
Office ruled that Farnsworth established
priority for electronic television with his Image Dissector. In the
meantime Farnsworth applied for additional patents, including one for color transmission and reproduction.
Despite the Patent Office decision,
litigation between Farnsworth and RCA dragged on for year, greatly distressing
the inventor. Finally in 1939 RCA agreed to settle the dispute by licensing Farnsworth’s patents for a
million dollars. That led directly to the famous public demonstration of the RCA television system, based on several
different patents, including Farnsworth’s at the New York World’s Fair on April 20, 1939.
But before that Farnsworth had
struggled. He parted ways with Philco in 1933 and then went to England in
hopes of raising money for his expensive litigation with RCA. There he
met John Logie Baird, a Scottish inventor
who had given the world first public demonstration of a working television
system in London in 1926 using a mechanical rotating disc device. The two
joined forces and Baird’s company began to market a system to the BBC in competition with EMI, which used Zworkink’s
patents. Eventually the BBC opted for the EMI system.
Farnsworth also demonstrated his
system in Germany, where it was used for experimental broadcasts of the 1936 Olympics.

Back in America, Farnsworth
continued his experimentation and filed several patents both for the
improvement of television and in new areas, including a ray for
airplanes and ships to penetrate fog.
During World War II in combination
with other patents on an improved cathode
ray tube to be used as an image receptor, it led to radar.
He founded his own company, Farnsworth Television and Radio Corporation
based in Fort Wayne, Indiana in 1936. The company
took on numerous defense contracts
during the World War II, including the development of radar and improvements to
sonar. But the small, undercapitalized company struggled to
make deliveries on time.
In 1951 International Telephone and Telegraph (ITT) bought his company and kept Farnsworth on a chief researcher working from a small
basement laboratory known as The Cave.
His improvements to the radar circular
sweep screen made possible modern air
traffic control systems.
ITT agreed to modestly fund
Farnsworth’s basic research into a new area, nuclear fusion. He developed a specialized set of fusion reaction tubes called fusors. Although he was able to
produce micro scale fusion reactions
in the lab, he could not figure out how to create large enough reactions to
become a potential power source. ITT soured on the expense of the project
and cancelled its support, causing Farnsworth to leave the company in 1966.
Farnsworth was never a household name like other inventors. He stumpped the panel on I've Got a Secret on the medium he pioneered.

Disillusioned
and drinking heavily, Farnsworth
transferred his research back to Utah where he worked in a laboratory provided
by Brigham Young University. He started a new, small firm, Philo T. Farnsworth and Associates and
lured some former colleagues from ITT to join him in Utah. He secured a
contract with NASA, but his bank called in its loans, which Farnsworth had secured with his home and pension.
The company collapsed and the Internal
Revenue Service padlocked his lab for failure to pay back taxes.
Despite the failure of his fusion
system to be commercially viable, it has become an invaluable tool in basic
research and fusors are used to produce particles
for use in cyclotrons and for other basic particle physics research.
With his family reduced to poverty
despite fathering one of the great industries of the century, Farnsworth fell
into deep depression and drank heavily, destroying his always fragile health. He died of pneumonia on March 11, 1971, largely in
obscurity. His widow Pem
campaigned relentlessly after his death to promote his place in the birth of
television.
Farnsworth was not THE inventor of
television. Many inventors contributed to what would ultimately be the
operating system that became practical and which after World War II exploded changing society and culture in ways Farnsworth could never
have imagined when he began sketching ideas for tubes as a 14 year old in an
Idaho science class.
Hello! I'm looking for the source of the second image from the top, the high school drawing of the electron tube. Any help tracking that down would be most appreciated!
