A vacuum tube, also called an electron tube, is a sealed glass in which electrons flow between electrodes separated by vacuum. The vacuum tube was invented in the early 20th century. With the invention of the vacuum tube, it became possible to amplify and transmit electrical energy. The ...
The point-contact transistor was invented by J. Bardeen and W. Brattain in December 1947 at the Bell Laboratories. The fascinating story of the discovery starts with the desire to produce a semiconductor triode by W. Shockley and the failure of his design of a field-effect transistor. The ...
Brattain, Bardeen, and Shockley of Bell Laboratories invented the BJT in 1947. The word “transistor” was coined by combining the two words “transfer” and “resistor”. Figure 2 shows the famous photograph of the first transistor, which started the modern age, the age of microelectronics. ...
The first transistor was invented in 1947 at Bell Labs by Michael John Bardeen, Walter Brattain and William Shockley. Find a term alphabetically:
The transistor was demonstrated for the first time at Bell Laboratories on 23rd December 1947. It had been developed a few days back and a patent was filed on 26th June 1948. The transistor was invented by William Shockley, Walter Brattain and John Bardeen. All three were awarded the Nobel ...

Transistors were invented at Bell Laboratories in 1947. Thesesolid-statedevices rapidly replaced the bulky vacuum tube as an electronic signal regulator. The invention of the transistor fueled the trend to miniaturize electronics. They're now considered one of the most significant developments in the ...
As happens sometimes with inventors and inventions, some people claim that the invention was invented by others. Such is also the case with the invention of the transistor. Some authorities claim that the basic idea of the solid state transistor (MOS field-effect transistor) was introduced by Ju...
