Barry Greenstein Autographs
Barry Greenstein (born December 30, 1954, in Chicago, Illinois) is an American professional poker player and former mathematics postgraduate student. He has won a number of major events, including three at the World Series of Poker and two on the World Poker Tour. Greenstein donates part of his profit from tournament winnings to charities, primarily Children Incorporated, earning him the nickname "the Robin Hood of poker". He was elected into the Poker Hall of Fame in 2011.
After graduating from Bogan High School, he earned a bachelor's degree in computer science from the University of Illinois at Urbana-Champaign. He studied for a PhD in mathematics without ever defending his completed dissertation.
According to his book, Ace on the River, Greenstein was doing well playing poker, but figured a more conventional job would improve his chances of adopting his stepchildren, so he went to work for the new startup company Symantec, where he worked on their first product Q&A. He left the company in 1991 at age 36.
