About Duncan McNaughton
Duncan Anderson McNaughton (December 7, 1910 – January 15, 1998) was a Canadian athlete, who competed mainly in the high jump. He went on to a career in petroleum geology. He competed for Canada in the 1932 Summer Olympics, held in Los Angeles, United States, in the high jump where he won the gold medal. Van Osdel helped coach McNaughton to his win during the final minutes of the competition. Later, in 1933 when McNaughton's medal was stolen from his car, Van Osdel—then a dentist—made a replica to replace it with a cast of his silver medal.
