Thomas "Tommy" Hearnsis an American former professional boxer. Nicknamed the "Motor City Cobra" and more famously "The Hitman", Hearns' tall and slender build allowed him to move up over fifty pounds in his career and become the first boxer in history to win world titles in four weight divisions: welterweight, light middleweight, middleweight, and light heavyweight. By later winning a super middleweight title, he also became the first to win world titles in five weight divisions...
