William Roetzheim was a national gymnastics champion in both college and the AAU. He first attended Fenger High and then moved to Lindblom to get coaching under legendary Coach Henry Smidl. He took the Public League title in 1944 and 1945 with unheard-of high scores, and helped regained the team championship for Lindblom from Senn. Roetzheim later participated in two Olympic Games and won multiple national championships in both the NCAA (for University of Illinois (Navy Pier) and Florida State) and the AAU. He coached state championship gymnastic teams at Proviso East and later coached the sport at University of Illinois (Chicago). He became one of the nation's most respected authorities on gymnastics, an international official in the sport, and an Olympic Games judge.
