Cus D'Amato Constantine "Cus" D'Amato (January 17, 1908 – November 4, 1985) was an Italian-American boxing manager and trainer who handled the careers of Mike Tyson, Floyd Patterson, and José Torres; all went on to become members of the International Boxing Hall of Fame. Several successful boxing trainers, including Teddy Atlas, Kevin Rooney, and Joe Fariello, were tutored by D'Amato. He was a proponent of the peek-a-boo style of boxing, in which the fighter holds his gloves close to his cheeks and pulls his arms tight against his torso. The style was criticized by some because it was believed that an efficient attack could not be launched from it.
