Jean-Claude Killy was a dominant figure in which sport in the 1960s and early 1970s?

Jean-Claude Killy (born 30 August 1943) also known as Gilette is a former French World Cup alpine ski racer. Born in Saint-Cloud, Hauts-de-Seine, he dominated the sport in the late 1960s. He was a triple Olympic champion, winning the three alpine events at the 1968 Winter Olympics, becoming the most successful athlete there. He also won the first two World Cup titles, in 1967 and 1968.

Killy was the first World Cup champion in 1967, winning 12 of 17 races to easily take the overall title. He also won the season standings in each of the three "Classic" alpine disciplines; he won all five of the downhill races and four of the five giant slalom races.

The following year, Killy won the Triple Crown of Alpine Skiing with a sweep of all three Olympic gold medals (downhill, giant slalom, and slalom) in controversial circumstances at the 1968 Winter Olympics in Grenoble, France. By finishing first in all races, he also captured the FIS world championship title in the combined event.

Electrical timing by Omega was accurate to one-hundredth of a second. Killy relied on his upper-body strength to hit the bar while already moving forward, giving himself a slight edge. This spectacular start appears to have helped him to beat his teammate Guy Perillat by a few hundredths in the Olympic downhill.
