Emma Calvé, born Rosa Emma Calvet (August 15, 1858 January 6, 1942), was a French operatic soprano. Calvé was probably the most famous French female opera singer of the Belle Époque. Hers was an international career, and she sang regularly and to considerable acclaim at the Metropolitan Opera House, New York, and the Royal Opera House, Covent Garden, London. She possessed a potent stage presence and was noted for her acting ability, stormy personality, and dramatic intensity. Contemporary accounts of her voice describe it as extraordinary, with a first-rate technique.
