Ellen Faull was born in Pittsburgh, Pennsylvania to a working-class family. During the Great Depression, she and her brothers and sisters went door-to-door selling their mother's home-baked bread to bring in extra money. She showed an early talent for singing and while still a teenager, her teacher introduced her to the conductor Eugene Ormandy who let her use his private box for all of the Philadelphia Orchestra's concerts.[3] She went on to study at the Curtis Institute of Music in Philadelphia and later in New York City.
As an opera singer, she sang throughout the United States and occasionally in Europe, but she was primarily associated with New York City Opera. She made her debut there in 1947 as Donna Anna in the company's first production of Don Giovanni and continued to sing leading roles with the company until 1978. Her final performance there was as Abigail in Jack Beeson's Lizzie Borden, a role she had created in the opera's world premiere in 1965.[4] As a recitalist, Faull was a champion of contemporary American composers. Ned Rorem once described her voice as "a cloud of peridot chiffon", and she sang in the world premieres of several of his works, including the 1957 premiere of The Poet's Requiem for soprano, chorus and orchestra.[5]
