Who invented transistors?

Answer 1

The first patents for the transistor principle were registered in Germany in 1928 by Julius Edgar Lilienfeld. In 1934 German physicist Dr. Oskar Heil patented the field-effect transistor. It is not clear whether either design was ever built, and this is generally considered unlikely.

On 22 December 1947 William Shockley, John Bardeen and Walter Brattain succeeded in building the first practical point-contact transistor at Bell Labs. This work followed from their war-time efforts to produce extremely pure germanium "crystal" mixer diodes, used in radar units as a frequency mixer element in microwave radar receivers. Early tube-based technology did not switch fast enough for this role, leading the Bell team to use solid state diodes instead. With this knowledge in hand they turned to the design of a triode, but found this was not at all easy. Bardeen eventually developed a new branch of surface physics to account for the "odd" behaviour they saw, and Bardeen and Brattain eventually succeeded in building a working device.

Answer 2

Who Invented Transistors

Answer 3

Transistors were invented at Bell Laboratories in New Jersey in 1947 by three brilliant US physicists: John Bardeen (1908–1991), Walter Brattain (1902–1987), and William Shockley (1910–1989).

The team, led by Shockley, had been trying to develop a new kind of amplifier for the US telephone system—but what they actually invented turned out to have much more widespread applications. Bardeen and Brattain made the first practical transistor (known as a point-contact transistor) on Tuesday, December 16, 1947. Although Shockley had played a large part in the project, he was furious and agitated at being left out. Shortly afterward, during a stay in a hotel at a physics conference, he single-handedly figured out the theory of the junction transistor—a much better device than the point-contact transistor.

While Bardeen quit Bell Labs to become an academic (he went on to enjoy even more success studying superconductors at the University of Illinois), Brattain stayed for a while before retiring to become a teacher. Shockley set up his own transistor-making company and helped to inspire the modern-day phenomenon that is "Silicon Valley" (the prosperous area around Palo Alto, California where electronics corporations have congregated). Two of his employees, Robert Noyce and Gordon Moore, went on to found Intel, the world's biggest micro-chip manufacturer.

Bardeen, Brattain, and Shockley were briefly reunited a few years later when they shared the world's top science award, the 1956 Nobel Prize in Physics, for their discovery. Their story is a riveting tale of intellectual brilliance battling with petty jealousy and it's well worth reading more about.

Answer 4

I don't know where these previous posters got their information but I am holding in my hand a book titled, "Strange Name Origins of Everyday Things" by Geoffery DeMarco, Ph. D. In it he states that the first transistor was invented in 1944 by a man named Murray Transistor (he then named it after himself.)

Answer 5

Herbert Matare was one of the inventors of the transistor. There are actually many because there are various electrical schematics for transistors, Depending on which type you're interested in.

Answer 6

They were Dr. John Bardeen, Dr. Walter Brattain and Dr. William Shockley. They were physicists working for Bell Labs.
