Francis Valentine Dinhaupt, who was known as Frank Valentino during much of his career as an opera singer and teacher at the Peabody Conservatory, died June 14 of kidney failure at a nursing home in Fairfax, Va. He was 84.
A baritone, he sang with the Metropolitan Opera for more than 20 years before teaching at Peabody from 1962 until his retirement in 1977. He lived in Severna Park during his years at Peabody, remaining there until he moved to Fairfax
about five years ago.
A native of New York City, he was reared in Denver and began studying music there. Mr. Dinhaupt went to Italy to study in 1926. He gained his professional name after an opera producer in Italy decided his name was too American and christened him Francesco Valentino.
