David Ross Cheriton (born March 29, 1951) is a Canadian-born computer science professor at Stanford University who has investments in technology companies. With an estimated net worth of US$3.3 billion (as of September 2014), Cheriton was ranked by Forbes as the 13th wealthiest Canadian and 508th in the world.
He briefly attended the University of Alberta where he had applied for both mathematics and music. Having been rejected by the music program, Cheriton went on to study mathematics and received his bachelor's degree from the University of British Columbia in 1973. Cheriton received his Masters and PhD degrees in computer science from the University of Waterloo in 1974 and 1978, respectively.
He spent three years as an Assistant Professor at his alma mater, the University of British Columbia, before moving to Stanford in 1981.
Cheriton founded and led the Distributed Systems Group at Stanford University, which developed the V operating system.
In August 1998, Stanford students Sergey Brin and Larry Page met with Bechtolsheim on Cheriton's front porch. Bechtolsheim wrote the first cheque to fund their company, Google, at the meeting, and Cheriton matched his $100,000 investment.
In 2001 Cheriton and Bechtolsheim founded another start up company, Palo Alto based Kealia. Kealia designed Magnum, a high capacity InfiniBand switch; Galaxy, a range of blade servers based on AMD's Opteron microprocessor; and Thumper, an enterprise grade network attached storage system. Kealia was bought by Sun Microsystems in 2004, with Thumper becoming the Sun Fire X4500.
Cheriton is an investor in and advisory board member for frontline data warehouse company Aster Data Systems, an early investor in in-video advertising company Zunavision, and he founded OptumSoft.
Although the Google investment alone would be worth over US$1 billion, Cheriton has a reputation for a frugal lifestyle, avoiding expensive cars or large houses. He was once included in a list of "cheapskate billionaires". On November 18, 2005, the University of Waterloo announced that Cheriton had donated $25 million to support graduate studies and research in its School of Computer Science. In recognition of his contribution, the school was renamed the "David R. Cheriton School of Computer Science."
In 1980, Cheriton married Iris Fraser; they divorced in 1994, embroiling the Silicon Valley community and their family in a dispute over the allocation of stock options in divorce for spousal and child support. They have four children.
