Annette Marie Sarah Kellerman (6 July 1886 – 6 November 1975) was an Australian professional swimmer, vaudeville star, film actress, writer, and business owner. Kellerman was one of the first women to wear a one-piece bathing costume, instead of the then-accepted pantaloons, and inspired others to follow her example. Kellerman's swimming costumes became so popular, that she started her own fashion line of one-piece bathing suits.
