Some famous names make up the list, including Floyd Mayweather Jr. who won titles in five different weight classes. Only Oscar De La Hoya and Manny Pacquiao have won more division titles in boxing history.
Joe Calzaghe is another distinguished name, boasting a 46-0-0 record. The "Pride of Wales" retired on 5th February 2009, and was hailed by Ricky Hatton as "the best British fighter we've ever had." High praise.
One of the more remarkable fighters on the list is the American Jimmy Barry. While Barry fought when the bantamweight category was not fully established, don't let this take away from the fact that he was undefeated in 71 bouts.
