At one point, Stella Walsh, a Polish-American sprinter, was the fastest woman in the world.
She won gold in 1932 and silver in 1936 for the 100m sprint. During her career, she set more than 100 national and world records and was inducted into the American Track and Field Hall of Fame. She lived her entire life as a woman, and even had a short-lived marriage to an American man. In 1980, Walsh was killed by mistake during an armed robbery at a shopping mall in Cleveland, Ohio. The postmortem revealed she had male genitalia. She was also found to have both male and female chromosomes.
