Silver went to Ernő Kolczonay of Hungary, extending the nation's podium streak to four Games despite the retirement of three-time medalist Győző Kulcsár. Philippe Riboud of France took bronze. Sweden's Rolf Edling, a two-time World Champion, made his third final in the event, but once again missed the podium.
