Medals: 1 Bronze (1 Total)
William Nelson won two AAU titles in 1899 and 1900, with the second one coming over future Olympic champion, [George Mehnert], in the finals. Four years later, Nelson was defeated at the Olympics by Mehnert's clubmate, [Gustav Bauer], in the first round. It was an exceptionally close match that required three overtimes before Bauer was declared the winner. Since there were only three wrestlers in the class, Nelson won a bronze medal.
