Eriksen was the first male alpine ski racer from outside the Alps to win an Olympic gold medal. He also won three gold medals at the 1954 World Championships in Åre, Sweden. Other accomplishments included being credited with devising "aerials", a freestyle skiing event, and helping revolutionize the world of alpine skiing in the United States, where he served as a ski instructor at many different ski schools. At Sugarbush Resort in Vermont, each Sunday afternoon, combining his gymnastics background and his skiing, Stein would demonstrate a flip on skis. For his Olympic medals, Eriksen earned the Holmenkollen Medal in 1952. It is said that Eriksen was skiing's "first superstar", since he was handsome, stylish and charismatic. Despite his fame, he maintained a very down-to-Earth personality. For example, he is quoted as saying, "Be tough, be confident. But you will never be a whole and happy person if you aren't humble".
