Early life and education

Clark was born in Plainview, Texas, on March 23, 1944. He dropped out of high school at 16 and spent four years in the Navy, where he was introduced to electronics. Clark began taking night courses at Tulane University's University College where, despite his lack of a high school diploma, he was able to earn enough credits to be admitted to the University of New Orleans. There, Clark earned his bachelor's and a master's degrees in physics, followed by a Ph.D. in computer science from the University of Utah in 1974.



After completing his doctorate, Clark briefly worked at the New York Institute of Technology's Computer Graphics Lab. He served as an assistant professor at the University of California, Santa Cruz (1974-1978) before moving to Stanford University as an associate professor of electrical engineering (1979-1982). Clark's research work concerned geometry pipelines, specialized software or hardware that accelerates the display of three dimensional images. The peak of his group's advancements was the Geometry Engine, an early hardware accelerator for rendering computer images based on geometric models which he developed in 1979 with his students at Stanford.

Silicon Graphics

In 1982, Clark along with several Stanford graduate students founded Silicon Graphics (SGI). The earliest Silicon Graphics graphical workstations were mainly terminals, but they were soon followed by stand-alone graphical Unix workstations with very fast graphics rendering hardware. In the mid-1980s, Silicon Graphics began to use the MIPS CPU as the foundation of their newest workstations, replacing the Motorola 68000.

By 1991, Silicon Graphics had become the world leader in the production of Hollywood movie visual effects and 3-D imaging. Silicon Graphics focused on the high-end market where they could charge a premium for their special hardware and graphics software.

Clark had differences of opinion with Silicon Graphics management regarding the future direction of the company, and departed in late January 1994.


In February 1994, Clark sought out Marc Andreessen who had led the development of Mosaic, the first widely distributed and easy-to-use software for browsing the World Wide Web, while employed at the National Center for Supercomputing Applications (NCSA). Clark and Andreessen founded Netscape, and developed the Netscape Navigator web browser. The founding of Netscape and its IPO in August 1995 launched the Internet boom on Wall Street during the mid-to-late 1990s. Clark's initial investment in Netscape was $4 million in 1994; he exited with $1.2 billion when Netscape was acquired by AOL in 1999.


In 1995, Clark became interested in streamlining the paperwork associated with the health-care industry. The resulting start-up, Healtheon, was founded in early 1996 with backing from Kleiner Perkins and New Enterprise Associates. Although Clark's original idea of eliminating the paperwork and bureaucracy associated with medical care was ambitious, it did lead to successes in administrative streamlining of medical records technology. However, an Atlanta, Georgia startup company, WebMD originally focused on medical content was also making similar in-roads. Knowing WebMD had financial backing from Microsoft, Clark decided to merge Healtheon with the original WebMD to form the WebMD Corporation (NASDAQ: WBMD). WebMD is a leader in health information on the Internet.

Other affiliations

In 1999, Clark launched myCFO, a company formed to help wealthy Silicon Valley individuals manage their fortunes. In late 2002, while Clark served on the board of directors, most of myCFO's operations were sold to Harris Bank and now operate as Harris myCFO.

Clark was chairman and financial backer of network-security startup Neoteris, founded in 2000, which was acquired by NetScreen in 2003 and subsequently by Juniper Networks.

Clark was a founding director and investor in the biotechnology company DNA Sciences, founded in 1998 to unravel the genetics of common disease using volunteers recruited from the Internet launched August 1, 2000 (see The New York Times). In 2003, the company was acquired by Genaissance Pharmaceuticals Inc.

Clark was the subject of the 1999 bestseller The New New Thing: A Silicon Valley Story by U.S. author Michael Lewis.

Clark was a notable investor in Kibu.com, an Internet website for teens, which received approximately $22 million in funding. The website shut down in 2000, returning its remaining capital to investors.

Clark coproduced the 2009 movie The Cove. His funding made possible the purchase and covert installation of some high-tech camera and sound-recording equipment required to capture the film's climactic dolphin slaughter. The film addresses the problem of whale and dolphin killing in Taiji, Wakayama, Japan.

Clark sits on the board and is one of the primary investors in the consumer facing mobile technology company Ibotta.

In 2017, Clark announced the launch of CommandScape, a cyber secure building management and automation platform.


Clark received the ACM SIGGRAPH Computer Graphics Achievement Award in 1984. In 1996, he received the Golden Plate Award of the American Academy of Achievement. He was a recipient of the 1997 Kilby International Awards, which honored him for his computer graphics vision and for enabling networked information exchange.

In 1988, Clark was an Award Recipient of the EY Entrepreneur of the Year Award in the Northern California Region.

Clark was awarded an honorary Doctor of Science (ScD) from the University of East Anglia in 1998.

Personal life

Clark has been married four times and has four children. In 2000, his daughter Kathy married Chad Hurley, a co-founder of YouTube, they were divorced in 2012. The divorce from his third wife of 15 years, Nancy Rutter, a Forbes journalist, is reported to have cost him $125 million in cash and assets in the settlement. Soon afterwards he began dating Australian model Kristy Hinze, 36 years his junior. Hinze became his fourth wife when they married in the British Virgin Islands on March 22, 2009. She gave birth to a daughter, Dylan Vivienne in September 2011, and later, Harper Hazelle, in August 2013.

In 2022 he made the largest residential real estate sale in Florida history, selling a 22-acre property in Manalapan, Florida to Larry Ellison for approximately $175 million. Clark had previously acquired the property in 2021 from the Ziff publishing family for $94 million.


Clark is an enthusiastic yachtsman but cannot sail in rough ocean races such as the Sydney-Hobart due to an arthritic condition in his ankles and prefers one-day regattas on the smoother waters of the Mediterranean, the Caribbean and off Newport, Rhode Island. In 2012, however, he commented that "after 28 years of owning boats, I'm over it."

He is the past owner of two important sailing yachts: He remains the current owner of two other large sailing yachts:

Clark is a passionate pilot who enjoys flying helicopters, gliders (built in Germany) and acrobatic aircraft (extra 300). His approach to learning to fly a helicopter was very much like trial and error as he explored how this aircraft works.


Clark has contributed to Stanford University, where he was an associate electrical engineering professor. In 1999, he pledged $150 million toward construction of the James H. Clark Center for Biomedical Engineering and related programs for interdisciplinary biomedical research. At the time, it was the largest-ever contribution to Stanford, other than the university's founding grant. Construction started in 2001 and was completed in the summer of 2003, as part of Stanford's Bio-X program. In September 2001, Clark rescinded $60 million of his initial pledge, citing anger over President Bush's restrictions on stem cell research. In a New York Times opinion piece, Clark said federal funding is essential for research in the United States, and he was not interested in funding research that could be suppressed for political reasons. President Barack Obama lifted the restrictions in question in 2009. In 2013, Clark pledged an additional $60 million to Stanford for interdisciplinary research in the life sciences, technology, and engineering. His commitment was finally completely fulfilled in 2020. Clark has donated an additional $10 million to fund fellowships at the Stanford Institute for Theoretical Physics.

In 2004, Clark and David Filo of Yahoo! each donated $30 million to Tulane University's School of Engineering for merit-based scholarships to provide education to deserving students regardless of financial situation in the discipline of engineering.

Clark is a board member for the national council of the World Wide Fund for Nature (WWF) and contributes towards the organization. The Perlman Music Program has recognized Clark for his continued philanthropic efforts towards their organization and their endowment fund.
