Annette Marie Sarah Kellermann was an Australian professional swimmer, vaudeville star, film actress, writer, and business owner.
She was one of the first women to wear a one-piece bathing costume, instead of the then-accepted pantaloons. Kellerman's swimming costumes became so popular, that she started her own fashion line of one-piece bathing suits. Kellermann helped popularize the sport of synchronised swimming; and authored a swimming manual. She appeared in several movies and was the first major actress to appear nude in a Hollywood production.
