Jack "Legs" Diamond, also known as Gentleman Jack, was an Irish American gangster in Philadelphia and New York City during the Prohibition era. A bootlegger and close associate of gambler Arnold Rothstein, Diamond survived a number of attempts on his life between 1916 and 1931, causing him to be known as the "clay pigeon of the underworld". In 1930, Diamond's nemesis Dutch Schultz remarked to his own gang, "Ain't there nobody that can shoot this guy so he don't bounce back?"
