She also created roles in several 20th-century operas, including Blanche in Poulenc's "Dialogues of the Carmelites".  Zeani made her professional debut in 1948 as Violetta in "La traviata" which would become one of her signature roles.  After her retirement from the stage in 1982, she became a well-known voice teacher.  She was married to the Italian bass Nicola Rossi-Lemeni from 1957 until his death in 1991.
