Thomas Hearns is a record-breaking former four weight world champion. In 1987, with his dominant victory over Juan Roldan, he became the first fighter to win world titles in four different weight classes.
The American began training with Emmanuel Steward at the famed Kronk Gym as a teenager, which now trains Tyson Fury. Steward altered Hearns from a skilful boxer into one of the hardest-hitting fighters of all time.
'The Hitman' was placed in the International Boxing Hall of Fame in 2012. He fought some of the greatest athletes of all time, including Sugar Ray Leonard, Roberto Duran and Marvin Hagler.
Following his first defeat to Leonard, Hearns moved up to super welterweight. He soon became the WBC champion and had to defend his title against legendary Panama opponent Roberto Duran, in a fight billed as 'Malice in the Palace'.

Hearns made a reported $45million during his career but spent most of it on his large extended family. Due to his financial issues, he was forced to auction off some of his prized belongings in 2010.
His family is well-known in the city of Detroit. Alongside his mother, he worked on Hearns Entertainment, which promoted the Mike Tyson-Andrew Golota bout in 2000.
