Roberto Duran was born in Panama in 1951 in a slum called La Casa de Piedra (House of Stone) and began sparring in a local gym when he was just eight years old. He took to boxing like the proverbial duck to water and turned pro at just 16 years old. After a difficult start he won 30 fights in a row, knocking out future and former featherweight world champions which culminated in him beating Ken Buchanan in Madison Square Garden for the WBA Lightweight Championship in 1972. Roberto 'Hands of Stone' Duran had arrived.

By the end of the seventies Duran had unified the lightweight division and set his sights on the welterweight division. The highlight was the Brawl in Montreal where he became the first person to beat Sugar Ray Leonard with his record then standing at an incredible 72-1. Following the infamous 'No Mas' rematch, Duran moved up to middleweight and became world champion again and had legendary dual's against fighters like Marvin Hagler and Tommy Hearns.

Known as a trash-talking aggressive brawler, Roberto Duran fought during one of the strongest boxing era's of all time and fought legends like Hagler, Hearns and Leonard but unlike those great fighters he managed over 100 professional victories in a career spanning over five decades to go down in history as one of the best fighters of all time.
