Agnes George de Mille (September 18, 1905 – October 7, 1993) was an American dancer and choreographer.
De Mille graduated from UCLA where she was a member of Kappa Alpha Theta sorority, and in 1933 moved to London to study at Marie Rambert's Ballet Club.
On the strength of Rodeo, de Mille was hired to choreograph Oklahoma! (1943). The dream ballet, in which dancers (Marc Platt, Katherine Sergava, and George Church) doubled for the leading actors, successfully integrated dance into the musical's plot. Instead of functioning as an interlude or divertissement, the ballet provided key insights into the heroine's emotional troubles. De Mille went on to choreograph over a dozen other musicals, most notably Bloomer Girl (1944), Carousel (1945), Brigadoon (1947), Gentlemen Prefer Blondes (1949), Paint Your Wagon (1951), Goldilocks (1957), and 110 in the Shade (1963).
De Mille's success on Broadway did not translate into success in Hollywood. Her only significant film credit is Oklahoma! (1955). She was not invited to recreate her choreography for either Brigadoon or Carousel. Nevertheless, her two specials for the TV series Omnibus, "The Art of Ballet" and "The Art of Choreography" (both televised in 1956), were immediately recognized as landmark attempts to bring serious dance to the attention of a broad public.
Her love for acting played a very important role in her choreography. De Mille revolutionized musical theatre by creating choreography which not only conveyed the emotional dimensions of the characters but also enhanced the plot. Her choreography, as a reflection of her awareness of acting, reflected the angst and turmoil of the characters instead of simply focusing on a dancer's physical technique.
De Mille regularly worked with a recognizable core group of dancers, including Virginia Bosler, Gemze de Lappe, Lidija Franklin, Jean Houloose, Dania Krupska, Bambi Linn, Joan McCracken, James Mitchell, Mavis Ray, and, at American Ballet Theatre, Sallie Wilson. Krupska, Mitchell, and Ray also served as de Mille's assistant choreographers, while de Lappe has taken an active role in preserving de Mille's work.
In 1953, de Mille founded the Agnes de Mille Dance Theatre, which she later revived as Heritage Dance Theatre.
De Mille was a lifelong friend of modern dance legend Martha Graham. The publisher of many books about dance, de Mille, in 1992, published Martha: The Life and Work of Martha Graham (ISBN 0-679-74176-3), a 509-page biography of Graham. De Mille had been working on the Graham manuscript for over 30 years.
At present, the only commercially available examples of de Mille's choreography are Fall River Legend (filmed in 1989 by the Dance Theatre of Harlem) and Oklahoma!
