Mike Tyson

Michael Gerard Tyson is a former American boxer. His nickname is Iron Mike. He
became three-time world heavyweight champion and at the age of twenty the youngest
heavyweight champion all time. Mike was seen as a ruthless boxer and outside the
ring, his explosive character brought him into contact with the law on several occasions. Tyson
grew up in the Brooklyn ghetto. His father disappeared when he was two years old, his
mother died when he was 16. Tyson became involved in crime and was occasionally in the
juvenile detention center. Boxing trainer Constantine "Cus" D'Amato became his mentor and replaced his father, taking him under his wing and getting him back on the right path. As an amateur boxer, Tyson impressed by winning 21 of his 24 fights and remained undefeated in his first year as a professional. After five years as a professional, "Iron Mike" was still undefeated: 37 wins, 33 of which were by knockout.
