Esther Jane Williams was an American competitive swimmer and actress.
Williams set multiple national and regional swimming records in her late teens as part of the Los Angeles Athletic Club swim team. Unable to compete in the 1940 Summer Olympics because of the outbreak of World War II, she joined Billy Rose's Aquacade, where she took on the role vacated by Eleanor Holm after the show's move from New York City to San Francisco. While in the city, she spent five months swimming alongside Olympic gold medal winner and Tarzan star, Johnny Weissmuller. Williams caught the attention of MGM scouts at the Aquacade. After appearing in several small roles, alongside Mickey Rooney in an Andy Hardy film, and future five-time co-star Van Johnson in A Guy Named Joe, Williams made a series of films in the 1940s and early 1950s known as "aquamusicals," which featured elaborate performances with synchronized swimming and diving.
From 1945 to 1949, Williams had at least one film listed among the 20 highest grossing films of the year.
