Babe Didrikson Zaharias
Now to be fair, Babe Didrikson Zaharias only competed in one Olympics for the United States, but her prowess and prolific mastery of sport earn her a place on this list. At the 1932 Los Angeles games, Zaharias qualified to compete in five sports, but was only allowed to compete in three (per the rules for women at the time). She took home golds for her skill at javelin and the 80-meter hurdles. Her silver came from the high jump -- it would have been a tie, if not for a technicality.
Shattering world records left and right, she also excelled at basketball, baseball, handball, volleyball, tennis, swimming, diving, boxing, cycling, skating, bowling, billiards and golf. Wow. Just wow.
And in an era where female athletes weren't well-loved, if not downright scorned, Zaharias and her phenomenal abilities helped to break down those barriers, paving the way for other female sport prodigies.
