Georg von Braun

Georg Gustaf Wilhelm von Braun was a Swedish horse rider who competed in the 1920 and 1924 Summer Olympics. In 1920 he and his horse Diana finished eighth in the individual eventing competition and won a gold medal with the Swedish eventing team. Four years later he finished 19th in the individual jumping and was a member of the gold medal-winning Swedish team. He did not receive any medal for that at the time, but is listed as a gold medalist for that too on IOC's site.
