Lawrence Revere (born Griffith K. Owens; November 5, 1915 – April 23, 1977[1]) was an author, casino pit boss, and professional blackjack player best known for his book Playing Blackjack as a Business.
Revere played under multiple aliases, including Leonard "Speck" Parsons and Paul Mann.
He also sold high-level strategies referred to as Revere Advanced Point Count (RAPC.)
These are now generally considered obsolete due to unnecessary complexity – although they are still valid and in use today.
But he was also known as a master of avoiding detection by casinos, and as an early proponent of composition-dependent strategy and floating advantage.
