At the Bell Telephone Laboratories, Murray Hill, NJ, USA, the first demonstration of a transistor took place on June 30th 1948. The Transistor was invented by three Americans, John Bardeen, Walter Houser Brattain, and William Shockley at Bell Telephone Laboratories. The essential element of the transistor was a tiny wafer of germanium, which basically is a semiconductor. At the time the world used vacuum tubes for electronics, the transistors could perform the same functions, but occupy a fraction of the space, and used a fraction of the power. and as a result of its success the three inventors shared the Nobel Prize in Physics in 1956.

A transistor is a semiconductor device with at least three terminals for connection to an electric circuit. The vacuum-tube triode, also called a (thermionic) valve, was the transistor’s precursor, introduced in 1907.
