The Evolution of Computer Hardware

When was the first transistor invented? Modern-day electronics began with the invention in

1947 of the transfer resistor Bardeen, Brattain & Shockley at Bell Laboratories

William Shockley

Born in London, grown up in CA. B.S. 1932, Ph.D. 1936 During WWII

Anti-submarine research & bomber pilot training Report on casualty of invading Japan: 1.7m to 4m Presidential Medal for Merit

Bell Labs Solid state physics group leader Invention of transistor in 1947

Silicon Valley Shockley Semiconductor Lab, Mountain View, CA Traitorous Eight formed Fairchild Semiconductor

Robert Noyce, Gordon Moore, etc

The Evolution of Computer Hardware

When was the first IC (integrated circuit) invented? In 1958 the IC was born when Jack Kilby at Texas

Instruments successfully interconnected, by hand, several transistors, resistors and capacitors on a single substrate
