Robert Noyce, Ph.D. (December 12, 1927 – June 3, 1990), nicknamed "the Mayor of Silicon Valley", co-founded Fairchild Semiconductor in 1957 and Intel in 1968. He is also credited (along with Jack Kilby) with the invention of the integrated circuit or microchip although Kilby's invention was 6 months earlier.

Noyce was born in Burlington, Iowa.

Noyce graduated with a BA in physics from Grinnell College in 1949 and a Ph.D. in physics from Massachusetts Institute of Technology in 1953.

While a student at Grinnell College, Noyce stole a pig from a nearby farmer for a college luau and then slaughtered it in Clark Hall. The prank nearly earned him expulsion, if not for the intervention of Grant O. Gale, a physics professor at the time. He later returned the favor by allowing the college to invest in Intel at an early stage.

He joined William Shockley at the Shockley Semiconductor Laboratory division of Beckman Instruments, but left with the "Traitorous Eight" to create the influential Fairchild Semiconductor corporation.

It is widely known that Noyce was disliked by one-time Intel CEO Andy Grove. Grove is notorious for his directness in finding fault. He thought Noyce's "nice guy" attitude irritating and felt it was ineffectual.

Intel's headquarters building, the Robert Noyce Building, in Santa Clara, California is named in his honor, as is the Robert N. Noyce '49 Science Center, which houses the science division of Grinnell College, as is the conference room of the Santa Fe Institute in New Mexico .

Noyce was awarded the IEEE Medal of Honor in 1978 "for his contributions to the silicon integrated circuit, a cornerstone of modern electronics."

Noyce died from heart failure in 1990, at the age of 62. He left behind the Robert Noyce Foundation, an institute that sponsors research in science and other technological programs.
