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.

[30]: 153 [31]: 145 Shive's invention sparked [32] Shockley's invention of the junction transistor. [30]: 143 A few months later he invented an entirely new, considerably more robust, type of transistor with a layer or 'sandwich' structure. This structure went on to be used for the vast majority of all transistors into the 1960s, and evolved ...
1947: The first transistor, a bipolar point-contact transistor, is invented by John Bardeen and Walter Brattain under the supervision of William Shockley at Bell Labs. 1948: The first atomic clock is developed at the National Bureau of Standards. 1948: Basic oxygen steelmaking is developed by Robert Durrer. The majority of steel manufactured in ...

John Bardeen (/ b ɑːr ˈ d iː n /; May 23, 1908 – January 30, 1991) [2] was an American mathematical physicist and electrical engineer.He is the only person to be awarded the Nobel Prize in Physics twice: first in 1956 with William Shockley and Walter Brattain for the invention of the transistor; and again in 1972 with Leon N. Cooper and John Robert Schrieffer for a fundamental theory of ...
The first practical transistor was the point-contact transistor, invented by the engineers Walter Houser Brattain and John Bardeen while working for William Shockley at Bell Labs in 1947. This was a breakthrough that laid the foundations for modern technology. [2] Shockley's research team also invented the bipolar junction transistor in 1952.
