The University of Michigan Museum of Art (UMMA) in Ann Arbor, Michigan with 94,000 sq ft (8,700 m2) is one of the largest university art museums in the United States. Built as a war memorial in 1909 for the university's fallen alumni from the Civil War, Alumni Memorial Hall originally housed U-M's Alumni office along with the university's growing art collection. Its first director was Jean Paul Slusser, who served from 1946 (first as acting director, then becoming director in 1947) to his retirement in 1957.
