Juanita Claxon, 62, who sang in opera and in recital under the name of Juanita Carter in the late 1940s and early 1950s, died Saturday at her home in Bethesda.

The Montgomery County medical examiner said Thursday the cause of the death had not yet been determined.

Miss Claxon was born in Frankfort, Ky., and grew up there and in Washington. She graduated from the Central High School.

She began her musical career in Washington, singing in church choirs as well as studying privately. She made her opera dubut as Melisandre in Debussy's "Pelleas and Melisandre" with the Philadelphia Opera, including that of Susanna in Mozart's "The Marriage of Figaro."

Her concert career included appearances with the National Symphony in Washington, the Boston Symphony under the great teacher Nadia Boulanger, with whom she also studied composition, at the Library of Congress in a program arranged by Boulanger, with the Toronto and Buffalo symphonies, and elsewhere.

She retired to Washington in the early 1953s to care for her parents, Charles A. and Clara E. Claxton.Her father died in 1972 and her mother in 1974.

Survivors include a brother, Charles W. Claxon, of Bethesda.

The family suggests that expressions of symphony be in the from of contributions to a charity of one's choice.
