Eugénie García
Wife and student of Manuel García, Eugénie (née Mayer) García (1818-1880) sang with the Opera Comique in Paris and became a noted singing teacher.
She left her husband after a few years, afterwhich he decamped to London, marrying an Englishwoman with whom he had two daughters after his estranged wife died at the age of sixty-two. Manuel and Eugénie's child, Gustave García, became an actor and wrote a book titled The Actor's Art.
