Thomas Steyer founded and currently co-manages the hedge fund Farallon Capital Management, headquartered in San Francisco. He is also a managing partner at private equity firm Hellman & Friedman. Steyer has donated generously to Bay Area-based philanthropies. Steyer and his wife, Kat Taylor, opened OneCalifornia Bank, a community development bank in Oakland, in 2007. (OneCalifornia later acquired ShoreBank Pacific to become One PacificCoast Bank.) They own a 2,000-acre grass-fed cattle ranch in Pescadero, Calif. The couple gave $40 million to Stanford University for sustainable-energy research in 2009. Steyer is also a trustee at the university. In 2010, Steyer donated more than $6 million to oppose Proposition 23, a measure supported by oil companies that would have weakened the state's global warming law.
