Marni Nixon
American singer and actress (1930-2016)
Margaret Nixon McEathron (February 22, 1930 – July 24, 2016), known professionally as Marni Nixon, was an American soprano and ghost singer for featured actresses in musical films. She was the singing voice of leading actresses on the soundtracks of several musicals, including Deborah Kerr in The King and I and An Affair to Remember, Natalie Wood in West Side Story, and Audrey Hepburn in My Fair Lady, although her roles were concealed from audiences when the films were released. Several of the songs she dubbed appeared on AFI's 100 Years...100 Songs list.
Besides her voice work in films, Nixon's career included roles of her own in film, television, opera and musicals on Broadway and elsewhere throughout the United States, performances in concerts with major symphony orchestras, and recordings.
Early life
Born in Altadena, California, to Charles Nixon and Margaret Elsa (née Wittke) McEathron, Nixon was a child film actress who also played the violin and began singing at an early age in choruses, including performing solos with the Roger Wagner Chorale. She went on to study singing and opera with, among others, Vera Schwarz, Carl Ebert, Boris Goldovsky and Sarah Caldwell. In 1947, having adopted the stage name "Marni Nixon", she made her Hollywood Bowl solo debut in Carmina Burana with the Los Angeles Philharmonic under conductor Leopold Stokowski.
Career
Early films and musicals
Nixon's career in film started in 1948 when she sang the voices of the angels heard by Ingrid Bergman in Joan of Arc (1948). The same year, she did her first dubbing work when she provided Margaret O'Brien's singing voice in 1948's Big City and then 1949's The Secret Garden. She sang for Jeanne Crain in Cheaper by the Dozen (1950) and dubbed Marilyn Monroe's high notes in "Diamonds Are a Girl's Best Friend" in Gentlemen Prefer Blondes (1953).

Why this record matters
The phrase “american singer and actress (1930-2016)” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Biographical claims are most persuasive when dates, appointments and relationships can be traced to records created close to the events described. The source revision retrieved here is dated Apr 14, 2026. The linked authority identifier is Q3087644. VIAF identifies the subject as 34649765. The Library of Congress control number is n83070039. 3 of 3 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1930, 2016, 1947 and 1948.
Public reputation and documentary evidence do not always develop together; absence from a summary is not evidence of historical absence. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
