David Einhorn is an American investor and hedge fund manager.

At the poker tables, Einhorn memorably finished third in the inaugural WSOP $1,000,000 Big One for One Drop for $4,352,000. He then donated the entire payout to the City Year Foundation, an education-focused nonprofit organization that partners with high-need public schools to provide full-time targeted student interventions.

Before that, Einhorn finished in 18th place in the largest poker tournament in history, the 2006 WSOP Main Event, which attracted 8,773 entrants. He donated his $659,999 in winnings to the Michael J. Fox Foundation.

"I came to the One Drop because it’s a lot of fun," Einhorn told PokerNews. "You get to play against the best players in the world. It’s like my summer vacation. It’s a great experience and so cool to be around so many great people who all want to contribute a great cause."
