In the mid-1950s, Harry Warburton was one of Switzerland’s top bobsledders. He got his first major taste of success at the 1954 World Championships, where he won the four-man event alongside Heiri Angst, Gottfried Diener, and Fritz Feierabend. Feierabend and Warburton were on a different Swiss crew at the 1955 edition, with Aby Gartmann and Rolf Gerber, and finished in second place behind their compatriots. They managed to best Angst and Franz Kapus in the two-man event, however, and claim gold. At the 1956 Winter Olympics Warburton teamed up with Heiri’s brother, Max, and took bronze in the two-man, while also coming in fourth in the four-man. He retired from active competition shortly after the Games.
