Annette Marie Sarah Kellerman (6 July 1886 – 6 November 1975) was an Australian professional swimmer, vaudeville star, film actress and writer. She 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.^[1]

She popularized the sport of synchronised swimming after her 1907 performance of the first water ballet in a glass tank at the New York Hippodrome. She has a star on the Hollywood Walk of Fame.
