ESPN is marking the 40th anniversary of Title IX by unveiling the top 40 female athletes of the past 40 years.
Janet Evans was only 17 years old and about 100 pounds when she secured her legacy.
The No. 15 woman in ESPN's countdown won three gold medals at the 1988 Summer Olympics in Seoul in the 400- and 800-meter freestyle and the 400-meter individual medley and was one of just two U.S. swimmers to win individual gold at the Games.
At the 1992 Barcelona Games, she repeated as champion in the 800 free -- the first woman ever to do so -- and just missed gold again when she was out-touched in the 400.
"An athlete comes along once in a generation who stands out -- a Mark Spitz or a Michael Phelps," says swimming commentator Rowdy Gaines, who won three golds at the 1984 Los Angeles Games. "Janet was that amazing icon. She was just a dinky little thing, but she hated to lose, and she was completely fearless."
