Frank Basky, 90, a sculptor who has exhibited works at the Smithsonian Institution and whose Carrara marble bas relief of Elizabeth Sprague Coolidge is in the Chamber Music Hall of the Library of Congress, died of cardio-respiratory failure Sunday at the Greater Southeast Community Hospital.

His other works included the gargoyles on the corners of the Chrysler Building in New York City, work on Grant's Tomb, and the Cathedral of St. John the Divine.

Mr. Basky came to Washington in 1963 and operated a studio in Hillcrest Heights. He also taught sculpting classes at the Davies Memorial Unitarian Church, in Camp Springs.

He came to this country from his native Budapest at the age of 14. He lived first in New York, where he studied under sculptor Karl Bitter and attended the Cooper Union. He was an honors graduate of the Beaux Arts Institute of Design.

While working for Grumman Aircraft during World War II, Mr. Basky helped speed production of new aircraft models. Mock-ups, which until that time took as long as three weeks to produce in wood, could now be made in an hour using plaster and sculpting techniques. Mr. Basky helped found Grumman's plaster and plastics department and served as foreman of the Long Island facility.

He also lived in Hollywood during the 1930s where he worked on set design for Fox Studios. He was president of the New York Modelers and Sculptors Union in the late 1920s and early 1930s.
