- David_Gelbaum abstract "David Gelbaum (born in c. 1950) is an American businessman and primarily green technology investor and environmental philanthropist. Since 2002, he has invested up to $500 million in clean-tech companies through his Quercus Trust, with a portfolio of businesses involved in nearly every aspect of the emerging green economy, be it renewable energy, smart electric grids, sustainable agriculture, electric cars or biological remediation of oil spills. He is CEO and Chairman of the Board of Entech Solar, a company he co-founded with Mark O'Neill.Gelbaum studied at University of California, Berkeley and Humboldt State College in Northern California before graduating with a B.A. in mathematics from University of California, Irvine. After graduating, he worked for a math professor, Edward O. Thorp, whose theories led to the establishment of what became Princeton Newport Partners, one of the first investment firms to use mathematical formulas to price stocks and derivatives. Princeton/Newport Partners collapsed in 1989, following the indictment of five executives in connection with a scheme to create illegal tax losses. Mr. Thorp and Mr. Gelbaum were not implicated, and an appellate court later overturned the other executives’ convictions.From 1972 to 1989, Gelbaum worked at the financial firm Oakley & Sutton performing quantitative modeling for stock price returns and derivative securities. He moved to TGS Management with a similar capacity until 2002.His investment focus is on the environmental technology and renewable energy industries having served on various public company boards in these industries, including the boards of Solar Enertech Corp., ThermoEnergy Corporation, Clean Power Technologies, Inc. and Energy Focus, Inc.".
