Yu, Albert Y. C.

Biographical Notes

Albert Y. C. Yu was born in Shanghai, China, in 1941. He received a B.S. from the California Institute of Technology and M.S. and Ph.D. degrees from Stanford University, all in Electrical Engineering. He joined Fairchild circa 1968 and is listed on a 1968 R&D organization chart in the Surface Physics section reporting to E. Snow. He joined Intel in 1972 and remained with the company for more than 30 years where he rose to the position of Senior Vice President. He oversaw the development of microprocessor families including the 386, the 486, many of the Pentiums and the Itanium. He was also involved with Intel’s entry into the optoelectronics business as well as international expansions. On retiring from Intel he served on the boards of a number of high technology companies, Venture Capital firms and non-profit organizations. He received the Distinguished Lifetime Achievement Award from CIE-USA and has published over 30 technical papers and two books: "Insider's View of Intel" (1995) and "Creating the Digital Future" (1998).
