Women weren't allowed to compete in the Olympic Games until 1900. That year in Paris, Switzerland's Hélène de Pourtalès, one of just 22 female athletes, became the first woman to medal, claiming gold in a team sailing event.
How times have changed.
The U.S. women have competed with historic results at this year's Tokyo Games, winning 60% of the country's medals, and the overall field of some 11,000 competitors is almost 49% female – from teens to mothers to 66-year-old Australian equestrian Mary Hanna, a grandmother.
The International Olympic Committee is even touting these as the "first gender-balanced Games in history.
