Australia-born Annette Kellerman took up swimming as treatment for a childhood condition that may have been mild polio and became a world-record holder in the sport. A pioneer of the one-piece bathing suit, she was famously arrested in Boston for indecency in 1907. The "Australian Mermaid" parlayed her notoriety into a successful career in Vaudeville and on the screen, making her feature film debut in 1914's "Neptune's Daughter." MGM turned her life story into a movie "Million Dollar Mermaid" starring Ester Williams in 1952. This photograph captures the profile of her in a nonchalant pose, looking contemplative.
