About Agnes de Mille
Agnes George de Mille (September 18, 1905 – October 7, 1993) was an American dancer and choreographer. == Early years == Agnes de Mille was born in New York City into a well-connected family of theater professionals. Her father William C. deMille and her uncle Cecil B. DeMille were both Hollywood directors. Her mother, Anna Angela George, was the daughter of Henry George, the economist. On her father's side, Agnes was the granddaughter of playwrights Henry Churchill de Mille and Matilda Beatrice deMille. Her paternal grandmother was of German-Jewish descent. She had a love for acting and originally wanted to be an actress, but was told that she was "not pretty enough", so she turned her attention to dance. In 1919, she enrolled in the Kosloff School of Dance in Los Angeles and was taught by Theodore Kosloff and his partner Natacha Rambova. When de Mille's younger sister was prescribed ballet classes to cure her flat feet, de Mille joined her. De Mille lacked flexibility and technique, though, and did not have a dancer's body.
