Blackjack and Professor

So what was his contribution to blackjack history that he was added to Blackjack Hall of Fame? Peter Griffin wrote his book called The Theory of Blackjack. It became the most popular book after Beat the Dealer by Edward O. Thorp.
Griffin's book is considered to be more comprehensive comparing to Thorp's book due to the more accurate and complete basic blackjack strategy for various numbers of decks as well as for any set of rules. Griffin explained the basic strategy from the view of mathematic, as it actually stands behind blackjack strategy & card counting systems.
It is worth mentioning that Peter Griffin book can't be understood by everyone as it was written for those having deep understanding of math. Otherwise, it will be hard to get to the point of the book.
Griffin is very honest man and he even wrote in the introduction to the book that he didn't win big with the help of his math strategies and, moreover, he even lost more than won.
His book describes perfectly the theory of playing blackjack, but the author left for players to apply it in practice.
