There's not a person in the gymnastics world who doesn't know of Nadia Comneci. In the 1974 Montreal Olympics, the Romanian-American gymnast became the first female athlete to score a perfect 10 (in 2004 the scoring system changed; a now-perfect score would be a 16) in an Olympic gymnastics event. She's also won five gold medals and is widely considered one of the greatest gymnasts in history.
