Gillis Grafström, Swedish figure skater and architect (d. 1938)

Gillis Emanuel Grafström (7 June 1893 – 14 April 1938) was a Swedish figure skater. He was born in Stockholm, Sweden. He won three successive Olympic gold medals in Men's Figure Skating (1920, 1924, 1928) as well as an Olympic silver medal in the same event in 1932, and three World Championships (1922, 1924, 1929). He and Eddie Eagan are the only athletes to have won a gold medal at both the Summer and Winter Olympic Games. Grafström has the further distinction of being the only person to have won an individual gold medal in both the Summer (1920) and Winter Olympics (1924, 1928), although Eagan remains the only one to have managed the feat in different disciplines. Grafstrom is one of the few athletes who have competed in both the Summer and Winter Olympic games. He is one of the oldest figure skating Olympic champions.
