Edward O. Thorp
Born in 1932 in Chicago, Edward O. Thorp is a mathematician who first established the card-counting system for blackjack in his book Beat the Dealer, then applied probability theory to financial markets — co-developing the first wearable computer with Claude Shannon along the way. He created the prototype for quantitative investing, proving that 'mathematics can win' at both the casino and on Wall Street.
