Paul Otellini became Intel’s fifth chief executive officer in 2005, during his eight-year tenure the company did more in revenue than it did during the company’s previous 45 years.

“We are deeply saddened by Paul’s passing,” Intel CEO Brian Krzanich said. “He was the relentless voice of the customer in a sea of engineers, and he taught us that we only win when we put the customer first.”

He joined Intel in 1974 and served in a number of positions, including general manager of Intel’s Peripheral Components Operation and the Folsom Microcomputer Division, and in 1989 as then-CEO Andy Grove’s chief of staff.
