Until his death, Stukelj was the oldest surviving Olympic Games gold medalist. A gymnast, he won two gold medals (and four other medals) in the 1924 games in Paris, gold and two bronzes in Amsterdam in 1928, and two silvers in the 1936 games in Berlin. He competed for Yugoslavia, but lived long enough to see his native Slovenia compete in the 1996 games under its own flag.
Professionally a judge, Stukelj still regularly worked out on the rings, and one of his classic moves is still known as the Stukelj maneuver. He was four days short of 101 when he died November 8 from a heart attack in Ljubljana, Slovenia.
