Piling it Higher and Deeper: The World’s Richest PhDs



Whether you’re a student or not, you’ve heard that getting a higher education will make a difference in earnings over your lifetime. Sure, some millionaires and billionaires have dropped out of college (e.g., Facebook co-founder Mark Zuckerberg, worth $35B) or even high school and have still done exceptionally well in life.

Several billionaires dropped out of their PhD programs to deal with success: Larry Page ($29.5B) and Sergey Brin ($29B), both co-founders of Google; Elon Musk ($12.2B; co-founder of PayPal, Tesla Motors, SpaceX, Solar City). Brin and Page were in Computer Science at Stanford, while Musk was in Applied Physics at Stanford. Had Page and Brin completed their doctorate degrees, they would have been near the top of this list, just below S. Robson Walton of the Walton billionaire clan.

On the flip side, some millionaires and billionaires have gone as far as completing one or more master’s degrees and a PhD. We’ve put together a list of 20 of the wealthiest PhD holders in world. Except for Robert Gore (#20) and John C. Martin (#19), everyone on this list is a confirmed billionaire (cross-referenced against Forbes). Yet, Gore is part of a family that is worth $5.8B, and Martin was in fact declared a billionaire in early 2014.


  • Net worth values are estimates only and can fluctuate wildly in just a few days — or even in a single day. The net worth data here was retrieved on Feb 19, 2015.
  • In the United States, a JD (Juris Doctor, aka Doctor of Jurisprudence) is a law degree that is equivalent to a professional doctorate. For that reason, some people listed here have a JD, not a PhD.
  • In some countries, an MD (Doctor of Medicine) is equivalent to a professional doctorate, but not in the United States. There is, however, an MD-PhD degree, and some people listed here hold such a degree. Since the majority of people on this list are American citizens, MD-only holder billionaires are not included.
  • This is not necessarily a comprehensive list, as the supposed net worth of some billionaire PhD holders was not confirmed and thus left out.
  • Several billionaire PhDs have passed away in recent years, including Amar G. Bose, founder of Bose Corp. (speaker systems, home entertainment systems); James Stewart, a Canadian mathematician who incorporated elements of Calculus (mathematical topic) into the architecture of his mansion; and Ray Dolby, founder of Dolby Laboratories (movie theater and home sound systems).



20. Robert Gore / University of Minnesota



Robert Gore is an engineer and scientist, and co-inventor (with father Bill Gore) of Gore-Tex waterproof fabric, an application of PTFE (polytetrafluoroethylene). Other applications of PTFE that the company has produced are for electrical wire insulation, medical use and more. Gore-Tex itself is often used for sporting gear. PTFE applications and particularly Gore-Tex have been a significant party of the Gore family’s wealth — estimated at $5.3B as of Jul 2014. Since the passing of Bill Gore, the money was divided up amongst the children of Bob and those of his siblings. Bob Gore’s net worth, is listed at $800M by Business Insider as of Oct 30, 2013, and as he is not on Forbes’ Billionaires list at the time of this writing, he is likely not a billionaire at present.

Gore completed a bachelor’s in chemical engineering at University of Delaware, and an MS and PhD (1963) in chemical engineering from University of Minnesota (U of M). U of M, located in the twin cities of Minneapolis and Saint Paul in the state of Minnesota, was established in 1851. It is a public university that is divided into these two campuses, about five miles from each other.


19. John C. Martin / University of Chicago



John C Martin has been the CEO since 1996 of Gilead Sciences, a drug and biotech firm. He also held the role of President from 1996 to 2008, then took on the Chairman role. He has held other Chairman roles, is currently a Director of Gilead and was a Director of California Healthcare Institute, has held several other executive roles at various companies and organizations, and was a on the Presidential Advisory Council. It’s hard to pinpoint Martin’s exact net worth as Mar 2014 Bloomberg article declared him a new billionaire (after 25 years with Gilead) at $1.2B, yet he is not listed on Forbes’ Billionaire’s list at the time of this writing. Our estimate based on the shares and options he holds, plus the net from previous exercising of options, suggests that he is worth between $800M and just under $1B.

Martin graduated with a BS from Purdue University, an MBA in marketing from Golden Gate University, and a PhD in organic chemistry (1977) from University of Chicago (U of C). The U of C, located in Chicago, Illinois, was established in 1890. It is a private research university funded with a donation by oil tycoon John D. Rockefeller.

12. David Ross Cheriton / University of Waterloo



David Cheriton could quite possibly be one of the most laid-back billionaires, sporting a bearded, sweater-wearing professor look, cutting his own hair, driving an old Volkswagen beetle and supposedly being quite frugal with his money in general, which once earned him a “cheapskate billionaire” moniker) His net worth was at $1.7B as of Mar 2013, reached $3.3B in Sept 2014 but is $2.9B as of Feb 2015 (with at least $1B of that being from his Google shares). Fortunately, he was willing to invest $100,000 of his own money in 1998 to promote the idea of two young Stanford PhD students, Larry Page and Sergey Brin, who founded Google with that money. (Another $100K was funded by Andy Bechtolsheim, a co-founder of Sun Microsystems.) Cheriton has also founded/ co-founded or funded several other tech startups, including OptumSoft, Granite Systems, Kealia and Arista Networks (which went IPO in 2014 and gained him an extra $540M in net worth in a few short months).
