Michael Gerard Tyson was born on June 30, 1966, in Cumberland Hospital in Brooklyn, New York, to Lorna Mae Smith Tyson and Jimmy Kirkpatrick. His biological father left when Mike was two; his mother Lorna died of cancer when he was sixteen. Raised in Brownsville, Brooklyn — one of New York City's most impoverished and violent neighborhoods — he was involved in crime from an early age, arrested approximately thirty-eight times before age thirteen. At eleven he was sent to the Tryon School for Boys in upstate New York, where he encountered a counselor who introduced him to trainer Cus D'Amato. D'Amato recognized immediately what he was looking at: the most physically gifted potential heavyweight he had encountered since Joe Louis.
Cus D'Amato became Tyson's legal guardian after his mother's death and relocated him to his home in Catskill, New York, where D'Amato and trainer Kevin Rooney developed Tyson's extraordinary raw power into the disciplined devastating technique that would make him the most feared heavyweight in boxing. D'Amato's peek-a-boo style — the high guard, the head movement, the rapid slipping punches that set up short powerful counters — was perfect for Tyson's physical profile: the unusually short neck, the extraordinary upper body strength, the speed that no heavyweight of his era could match. D'Amato died in November 1985, one month before Tyson turned professional.
Tyson's amateur career (186-18) and his early professional record demonstrated a combination of physical gifts and technical development that had not been seen in heavyweight boxing since a young Muhammad Ali. His early professional knockouts — many of them over within one round, some within seconds — generated a public persona of invincibility that preceded his actual achievements. At twenty years, four months, and twenty-two days, he became the youngest heavyweight champion in history by defeating Trevor Berbick in 1986. He unified the heavyweight title over the following years and, at his peak between 1985 and 1990, was regarded as the most dangerous heavyweight since Sonny Liston.
Tyson's career after his 1990 loss to James 'Buster' Douglas — which ended his period of total domination and remains one of the greatest upsets in sporting history — became increasingly marked by the personal difficulties that had always existed alongside his ring brilliance. His 1992 rape conviction, the three years in prison, the return to boxing and his disqualification for biting Evander Holyfield's ear in 1997, the bankruptcy that followed extraordinary earning — these were the chapters of a life that the extraordinary boxing ability had not resolved. His 2024 exhibition match against YouTube star Jake Paul, at age fifty-eight, demonstrated both his continued marketability and the distance traveled from his peak.
