In amateur boxing, light heavyweight is a weight division above and up to, falling between middleweight and heavyweight. In professional boxing, the division is above and up to, falling between super middleweight and cruiserweight. The light-heavyweight class has produced some of boxing's greatest champions: Bernard Hopkins, Tommy Loughran, Billy Conn, Joey Maxim, Archie Moore, Michael Moorer, Bob Foster, Ann Wolfe, Michael Spinks, Dariusz Michalczewski, Roy Jones, Jr., Joe Calzaghe and Zsolt Erdei.Many light heavyweight champions unsuccessfully challenged for the heavyweight crown until Michael Spinks became the first reigning light heavyweight champion to win the heavyweight championship. Bob Fitzsimmons captured the light-heavyweight championship after losing his heavyweight championship. Two all-time great heavyweight champions, Ezzard Charles and Floyd Patterson, started out as light heavyweights. Charles defeated Archie Moore and Joey Maxim several times in non-title bouts before becoming heavyweight champion and Patterson lost an eight-round decision to Joey Maxim before becoming heavyweight champion himself. Evander Holyfield successfully moved up from the light-heavyweight division to the cruiserweight division and eventually the heavyweight division and became undisputed champion of the latter two.
