Bruce Moore, 74, an award-winning sculptor and a former director of the Maryland Institute's Rineheart School of Sculpture in Baltimore, died of pneumonia Thursday at the Mar-Salle Convalescent Center here.

Mr. Moore's works in plaster, stone, bronze, clay and terra cotta included portrait busts, human and animal figures and medals. He also was known for his drawings and taught drawing at the New York School of Applied Design for Women in 1941 and 1942. For the next two years, he served as director of the Rinehart School of Sculpture.

Among his public works are a bronze portrait statue of Gen. William (Billy) Mitchell for the Smithsonian's Air and Space Museum, sculpture for the National Memorial of the Pacific in Honolulu, two heroic tigers for the campus of Princeton University, the Hooker Memorial Doors of the Grace Cathedral in San Francisco and doors and a fountain group for the Wichita (Kan.) Art Association.

A native of Bern, Kan., Mr. Moore began studying at the Kansas City Art Institute in Missouri at the age of 15. The following year, he entered the Pennsylvania Academy of Fine Arts, from which he graduated in 1925. He was a Guggenheim Fellow from 1929 to 1931 and a visiting sculptor at the American Academy in Rome, Italy, for two years in the late 1930's.

He also taught modeling and the history of sculpture at the University of Wichita for a year in the late 1920's.

His drawings and lithographs of animals were engraved on glass shapes by the designers of Steuben glass.

Mr. Moore's awards include the Widener Gold Medal from the Pennsylvania Academy of Arts, the Samuel F.B. Morse Medal from the National Academy of Design, of which he was a member, and the J. Saltus Medal from the American Numismatic Society, of which he was a Fellow.

He served in the Army in World War II.

He and his wife, the former Alice Hegli, who is an artist, were married in 1931. They had lived in Washington since 1950 and also had maintained studios in Kansas, Connecticut, New York City and in Italy.

Besides his wife, survivors include a sister, Frances Moore Huston of Albuquerque, N.M.
