Who was the first person to make a transistor?

Answer 1

The first patent for the field-effect transistor principle was filed in Canada by Austrian-Hungarian physicist Julius Edgar Lilienfeld on October 22, 1925, but Lilienfeld did not publish any research articles about his devices. In 1934 German physicist Dr. Oskar Heil patented another field-effect transistor. There is no direct evidence that these devices were built, but later work in the 1990s shows that one of Lilienfeld's designs worked as described and gave substantial gain. Legal papers from the Bell Labs patent show that Shockley and Pearson had built operational versions from Lilienfeld's patents, yet they never referenced this work in any of their later research papers or historical articles. On 17 November 1947 John Bardeen and Walter Brattain observed that when electrical contacts were applied to a crystal of germanium, the output power was larger than the input. William Shockley saw the potential in this and worked over the next few months greatly expanding the knowledge of semiconductors and is considered by many to be the 'father' of the transistor.

1956 John Bardeen, Walter H. Brattain and William Shockley received the Nobel Prize in Physics for inventing the first silicon based transistor

Answer 2

The transistor was invented at Bell Labs in 1948 by Walter Brattain, John Bardeen, and William Shockley. It became commercially available for use in consumer goods such as transistor radios during the early 1950's.

Answer 3

John Bardeen, Walter H. Brattain, and William B. Shockley built the first successful

transistor in 1947. Their achievement was recognized with the 1956 Nobel Prize in

Physics.

Answer 4

Transistors were made to aid in both amlification and to act as switchs.
