Edward Thorp

American mathematics professor Edward Oakley Thorp is famous in gambling circles as the author of the 1962 book, ‘Beat the Dealer’, which is nowadays billed ‘The book that made Las Vegas change the rules’. Shortly after being awarded his doctorate in mathematics by the University of California, Los Angeles in 1958, Thorp played blackjack in Las Vegas. He realised that, unlike other games of chance, each hand of blackjack is influenced by the cards already dealt from the deck and set about developing a winning system based on mathematical probability.

After several years of academic research, during which he used computer simulations to calculate the precise probabilities of winning or losing for decks of various composition and number, Thorp first published his conclusions in an academic paper, ‘A Favorable Strategy for 21’. His work attracted the attention of Emmanuel ‘Manny’ Kimmel – unbeknown to Thorpe an illegal bookmaker with Mafia connections – who offered him $10,000 to take an ‘applied research’ trip to Las Vegas, in return for 10% of any winnings. Thorp naively accepted and duly won $13,000 in the space of a few days. The following year, Thorp published the first edition of ‘Beat the Dealer’, which introduced card counting and basic blackjack strategy to the masses and has been a bestseller ever since.
