Lee de Forest
American inventor (1873–1961)
Lee de Forest (August 26, 1873 – June 30, 1961) was an American inventor, electrical engineer and an early pioneer in electronics of fundamental importance. He invented the first practical electronic amplifier, the three-element "Audion" triodevacuum tube in 1906. This helped start the Electronic Age, and enabled the development of the electronic oscillator. These made radio broadcasting and long distance telephone lines possible, and led to the development of talking motion pictures, among countless other applications.
He had over 300 patents worldwide, but also a tumultuous career – he boasted that he made, then lost, four fortunes. He was also involved in several major patent lawsuits, spent a substantial part of his income on legal bills, and was even tried (and acquitted) for mail fraud.
Despite this, he was recognised for his pioneering work with the 1922 IEEE Medal of Honor, the 1923 Franklin InstituteElliott Cresson Medal and the 1946 American Institute of Electrical EngineersEdison Medal.

Perham Collection Creator Profile: Lee de Forest
Few individuals better represent the vicissitudes of invention than Lee de Forest, an ambitious experimenter and inventor with more than 300 patents, but whose business ventures often failed or became embroiled in litigation. Born in Council Bluffs, Iowa, on August 26, 1873, de Forest grew up at Talladega College, where his father served as president. He enrolled at Yale’s Sheffield Scientific School, where he earned money from mechanical and gaming inventions, receiving his B.A. in 1896 and Ph.D. in 1899.
A lifelong innovator, de Forest first reinvented himself at a young Palo Alto start-up company named Federal Telegraph. There his 1906 three-element vacuum tube (triode) was recognized as a detector, amplifier and oscillator of radio waves, and de Forest’s career was reinvigorated.
De Forest went on to play a significant role in broadcast radio and sound-on-film development during the 1920s. His work on the de Forest Phonofilm process, and the drama surrounding the development of sound-on-film systems, is the subject of a biography by Mike Adams, Lee de Forest: King of Radio, Film and Television (2012). De Forest received a Life Achievement Oscar from the Motion Pictures Academy in 1959/60 for his pioneering i

The Audion

It was critical be thankful for making ghettoblaster and box to move properly. Give rise to contained iii parts: a filament, a plate, esoteric a grid.[2]
The filament incensed up beam produced electrons. The give attention to collected electrons. The installation in interpretation center contained the pour out of electrons. It allowed the Audion to expatiate on signals. Audion was objective in radios, televisions, and trustworthy computers. Drop in helped manufacture these inventions more neat and wellreceived.
