Blanche Thebom (September 19, 1915 – March 23, 2010[1]) was an American operatic mezzo-soprano, voice teacher, and opera director. She was part of the first wave of American opera singers that had highly successful international careers.[2] In her own country she had a long association with the Metropolitan Opera in New York City which lasted 22 years. Opera News stated, "An ambitious beauty with a velvety, even-grained dramatic mezzo, Thebom was a natural for opera: she commanded the stage with the elegantly disciplined hauteur of an old-school diva, relishing the opportunity to play femmes du monde such as Marina in Boris Godunov, Herodias and Dalila.
