Blanche Thebom was an American mezzo-soprano who sang with the Metropolitan Opera in New York City for almost twenty years.
She was born in Monessen, Pennsylvania and raised in Canton, Ohio.
In 1957 she came to London to sing Dido in the major production at Covent Garden of Berlioz?s Les Troyens. In this she made effective use of he spectacularly long hair, allowing it to fall down her back as she ascended the funeral pyre at the end.
Upon her retirement from the Metropolitan ca. 1960, she taught and directed opera performance in Atlanta and Little Rock until around 1980. She appeared in summer theatre revivals of Broadway musicals such as The Sound of Music in Atlanta.
