David Einhorn isn't good just at playing the markets. He also has quite a poker face. The Greenlight Capital chief won a hefty $660,000 at the recent World Series of Poker held in Las Vegas. Einhorn bested poker pro David Williams but eventually lost to Jamie Gold.
Still, defeat didn't leave Einhorn with a chip on his shoulder. After cashing out his winnings, he donated the entire pot to Michael J. Fox's New York-based Foundation for Parkinson's Research. Einhorn has said that his grandfather suffered from Parkinson's.
