Laurence Kim Peek (November 11, 1951 – December 19, 2009) was an American savant. Known as a "megasavant",[2][3] he had an exceptional memory, but he also experienced social difficulties, possibly resulting from a developmental disability related to congenital brain abnormalities. He was the inspiration for the character of Raymond Babbitt, played by Dustin Hoffman in the movie Rain Man. Unlike Babbitt, who had autism, Peek probably also had FG syndrome.[4][5]
