At age 22, D'Amato opened the Empire Sporting Club with Jack Barrow at the Gramercy Gym.
Notable boxers trained Floyd Patterson Under D'Amato's tutelage,
Floyd Patterson captured the
Olympic middleweight gold medal in the 1952
Helsinki games. D'Amato then guided Patterson through the professional ranks, maneuvering Patterson into fighting for the title vacated by
Rocky Marciano. After beating
Tommy "Hurricane" Jackson in an elimination fight, Patterson faced Light Heavyweight Champion
Archie Moore on November 30, 1956, for the World Heavyweight Championship. He beat Moore by a knockout in five rounds and became the youngest World Heavyweight Champion in history at the time, at the age of 21 years, 10 months, three weeks and five days. He was the first Olympic gold medalist to win a professional Heavyweight title. Patterson and D'Amato split after Patterson's
second consecutive 1st-round KO loss to
Sonny Liston, although his influence over the former two-time champion had already begun to diminish. With the victory Torres became the third Puerto Rican world boxing champion in history and the first Latin American to win the world Light Heavyweight title.
Mike Tyson After Patterson and Torres' careers ended, D'Amato worked in relative obscurity. He eventually moved to
Catskill,
New York, where he opened a gym, the Catskill Boxing Club. He adopted Tyson after Tyson's mother died. D'Amato trained him over the next few years, encouraging the use of
peek-a-boo style boxing, with the hands in front of the face for more protection. D'Amato was briefly assisted by
Teddy Atlas, and later
Kevin Rooney, a protégé of D'Amato, who emphasized elusive movement. It is unclear at exactly which age (11 or 12) Tyson first became seriously interested in becoming a professional boxer.
"Irish" Bobby Stewart, a former Golden Gloves Champion, was approached by Tyson while working as a counselor at the Tryon School For Boys. Tyson knew of Stewart's former boxing glory and specifically asked to speak with Stewart who immediately took on a gruff attitude to the subject after witnessing Tyson's terrible behavior in his first days at the school. Bobby Stewart introduced Mike Tyson to D'Amato when Tyson was around 12 or 13 years old, after Stewart stated he had taught Tyson all he could about boxing technique and skill. D'Amato died a little over a year before Tyson became the youngest world heavyweight titleholder in history at the age of 20 years four months, thus supplanting Patterson's record. ==Personal life==
