Eugenia Mantelli (1860- 3 March 1926) was an Italian opera singer who had a prolific career in Europe, the United States, and South America from the 1880s through the early part of the twentieth century. She possessed a flexible warm voice with a wide vocal range that, while focusing mostly within the mezzo-soprano repertoire, enabled her to sing roles normally associated with contraltos and sopranos. Indeed, during her lifetime she was often identified as either a mezzo-soprano or a contralto by music critics without much consistency. While she had an excellent vocal technique and an exceptionally beautiful tone quality, her gifts as an actress and interpreter were only mediocre.[1]
