Who developed the transistor?
Transistor
The transistor is the fundamental building block of modern electronic devices, and is ubiquitous in modern electronic systems. Julius Edgar Lilienfeld patented a field-effect transistor in 1926[1] but it was not possible to actually construct a working device at that time. The first practically implemented device was a point-contact transistor invented in 1947 by American physicists John Bardeen, Walter Brattain, and William Shockley. The transistor revolutionized the field of electronics, and paved the way for smaller and cheaper radios, calculators, and computers, among other things. The transistor is on the list of IEEE milestones in electronics,[2] and Bardeen, Brattain, and Shockley shared the 1956 Nobel Prize in Physics for their achievement.[3]

On January 12, 1956, a diffused base transistor was unveiled at Laureldale before top military brass at a solid-state diffusion symposium. That was the same year that Bell Labs' scientists Bardeen, Brattain, and Shockley received the 1956 Nobel Prize in physics for the invention of the transistor. "Bell Laboratories scientists in Murray Hill, N.J., may have won the Nobel Prizes and gotten most of the press, but Allentown and Reading delivered the goods," notes Stuart W. Leslie, a historian of science at Johns Hopkins University in Baltimore.
