Kellerman was famous for advocating the right of women to wear a one-piece bathing suit, which was controversial at the time. According to an Australian magazine, “In the early 1900s, women were expected to wear cumbersome dress and pantaloon combinations when swimming. In 1907, at the height of her popularity, Kellerman was arrested on Revere Beach, Massachusetts, for indecency – she was wearing one of her fitted one-piece costumes.”
