(CNN) You might not have heard of Jean Vuarnet, but if you've ever been skiing the chances are you have participated in his legacy.

It may seem almost instinctive for skiers nowadays to adopt the "tuck" position when speeding downhill, but Vuarnet, who died Monday aged 83, helped pioneer the technique more than five decades ago.

The Frenchman won gold at the 1960 Winter Olympics in Squaw Valley, California, where he adopted the egg-shaped "tuck" position that is used widely in all forms of skiing today. Vuarnet bent his knees and back to adopt a faster, aerodynamic squat that helped propel him to victory.

But that wasn't all: Vuarnet also became the first man to win gold on metal, rather than wooden skis.

The streamline stance later became known as "l'oeuf," the French word for an egg. A glass statue of Vuarnet cast in this iconic position was unveiled in the Alpine town of Morzine, Southern France in 2010, on the 50th anniversary of his gold medal win.
