The only person to win the same event in both Summer and Winter Olympics was Sweden's Gillis Grafström. He won figure skating gold medals at the 1920 Olympics in Antwerp, when the sport was part of the programme for the Summer Games, and then at the inaugural Winter Olympics in Chamonix in 1924. He retained his title at St Moritz in 1928 and claimed silver at Lake Placid 1932, where his chances of a fourth consecutive gold medal were ended when he collided with a photographer on the ice.
