David Ross Cheriton is a Canadian computer scientist, mathematician, billionaire businessman, philanthropist, and venture capitalist. He is a computer science professor at Stanford University, where he founded and leads the Distributed Systems Group. He is a distributed computing and computer networking expert, with insight into identifying big market opportunities and building the architectures needed to address such opportunities. He has founded and invested in technology companies, including Google, where he was among the first investors; VMware, where he was an early angel investor; and Arista, where he was cofounder and chief scientist. He has funded at least 20 companies. Cheriton was ranked by Forbes with an estimated net worth of US$5.9 billion, as of 2019. He has made contributions to education, with a $25 million donation to support graduate studies and research in the School of Computer Science at the University of Waterloo, a $7.5 million donation to the University of British Columbia, and a $12 million endowment in 2016 to Stanford University to support Computer Science faculty, graduate fellowships, and undergraduate scholarships.
Cheriton founded and led the Distributed Systems Group at Stanford University, which developed the operating system V. He has published profusely in the areas of Distributed Systems and Networking and won the prestigious SIGCOMM award in 2003, in recognition for his lifetime contribution to the field of communication networks. Cheriton was the mentor and advisor of students such as: Sergey Brin and Larry Page, Kenneth Duda, Hugh Holbrook, Sandeep Singhal, and Kieran Harty. As of 2016, Cheriton is working with Stanford students on transactional memory, making memory systems that are resilient to failures.
Industry
Cheriton cofounded Granite Systems with Andy Bechtolsheim. The company developed gigabit Ethernet products. It was acquired by Cisco Systems in 1996. In August 1998, Stanford students Sergey Brin and Larry Page met Bechtolsheim on Cheriton's front porch. At the meeting, Bechtolsheim wrote the first cheque to fund their company, Google, and Cheriton joined him with a $200,000 investment. Cheriton was also an early angel investor in compute virtualization leader VMware, which was later acquired for $625M by EMC in 2004. VMware had a successful public offering in 2007. In 2001 Cheriton and Bechtolsheim founded another start-up company, Palo Alto based Kealia. Kealia designed a high-capacity streaming video server; Galaxy, a range of 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. In 2004, Cheriton cofounded and was chief scientist of Arista Networks, where he worked on the foundations of the Extensible Operating System. Arista had a successful public offering in 2014. Cheriton is an investor in and advisory board member for frontline data warehouse company Aster Data Systems, which was acquired by Teradata in 2011 for $263M. Cheriton is also one of the earliest investors in Tintri, a storage virtualization company founded by his student Kieran Harty. Cheriton was also an early investor in in-video advertising company Zunavision, and he founded OptumSoft. In 2014, Cheriton cofounded and invested in Apstra, Inc. In 2015, Cheriton cofounded and invested in BrainofT, Inc..
Lifestyle
Although the Google investment alone would be worth over US$1 billion, Cheriton has a reputation for a frugal lifestyle, avoiding costly 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 2009, Cheriton donated $2 million to the University of British Columbia, which will go to fund the Carl Wieman Science Education Initiative. Cheriton more recently donated $7.5M to fund a new chair in computing, and a new course on computational thinking. Cheriton has also funded two graduate student fellowships and one undergrad fellowship at Stanford, and donated several millions of dollars to Stanford to fund research. He campaigned against asynchronous transfer mode that was favored by telephone carriers, preferring Ethernet, which he saw as a simpler, proven option. Ethernet gradually trumped alternatives.
Personal life
In 1980, Cheriton married Iris Fraser. They had four children, and divorced in 1994.
