In 1951 she sang Bizet's Carmen at la Monnaie of Brussels. She then addressed the great roles of lyrico-dramatic soprano: in 1952, she made a remarkable debut at the Paris Opera where she sang at both the Opéra Garnier and the Opéra-Comique:
She created Henri Rabaud's Numance, interpreted the title role of Charpentier's Louise, Blanche de la Force in Poulenc's Le Dialogue des Carmélites, Tatiana in Tchaikovsky's Eugene Onegin, and also Octavian in Strauss's Rosenkavalier alongside Régine Crespin or Elisabeth Schwarzkopf. For more than thirty years, she has been active in the major theatres of the provinces: Toulouse, Strasbourg, Marseille, Bordeaux and Nice. Especially sought abroad for her embodiments of Puccini's Tosca, and Verdi's Aida and Elisabeth in Don Carlos, she triumphed in these roles in Buenos Aires, Brussels, Geneva, Rome, Rio, Naples, London.

She was the director of the Atelier lyrique of the Opéra national du Rhin and teacher at the 9th arrondissement of Paris conservatory until 1992. She last lives and teaches in Paris.
