Detroit Institute of Arts
Michigan, USA


The DIA's collection is among the top six in the United States, with more than 65,000 works. The foundation was laid by William Valentiner, who was director from 1924 to 1945. 


Among his notable acquisitions are Mexican artist Diego Rivera's Detroit Industry fresco cycle, which Rivera considered his most successful work, and Vincent van Gogh's Self-Portrait, the first Van Gogh painting to enter a U.S. museum collection.
