The first transistor was successfully demonstrated on December 23, 1947, at Bell Laboratories in Murray Hill, New Jersey. Bell Labs was the research arm of American Telephone and Telegraph (AT&T). The three individuals credited with the invention of the transistor were William Shockley, John Bardeen and Walter Brattain. The introduction of the ...
A stylized replica of the point-contact transistor invented at Bell Labs on December 23, 1947. The point-contact transistor was the first type of transistor to be successfully demonstrated. It was developed by research scientists John Bardeen and Walter Brattain at Bell Laboratories in December 1947.
Invention year: 1947; 78 years ago () Number of terminals: 3: ... The invention of the transistor & the birth of the information age; Warnes, Lionel (1998).
The invention of the transistor in December 1947 is one of the hallmark moments in humanity’s technological history, right up there with Maxwell’s equations and Alessandro Volta’s battery.
Walter Houser Brattain (/ ˈ b r æ t ən /; February 10, 1902 – October 13, 1987) was an American physicist at Bell Labs who, along with fellow scientists John Bardeen and William Shockley, invented the point-contact transistor in December 1947. [1] They shared the 1956 Nobel Prize in Physics for their invention.
The first transistor hi-fi system was developed by engineers at GE and demonstrated at the University of Philadelphia in 1955. [9] In terms of commercial production, The Fisher TR-1 was the first "all transistor" preamplifier, which became available mid-1956. [10] In 1961, a company named Transis-tronics released a solid-state amplifier, the ...
John Bardeen, William Shockley and Walter Brattain invented the first working transistor (1947). The first working transistor was a point-contact transistor invented by John Bardeen and Walter Houser Brattain at the Bell Telephone Laboratories (BTL) in 1947. [22] William Shockley then invented the bipolar junction transistor at BTL in 1948. [23]
Teal joined Bell Labs in 1930 and would remain employed there for 22 years. [1] During his time there, he continued to work with germanium and silicon. [1] When William Shockley's group at Bell Labs invented the transistor in 1947, Teal realized that substantial improvements in the device would result if it was fabricated using a single crystal, rather than the polycrystalline material then ...
