Michael Graves is one of the few post-modernists on our list. Born in Indianapolis, Ind., he had a long-standing interest in drawing and painting, which influenced his architecture later in life. Graves worked with Carl Strauss, Ray Rousen, and George Nelson. Some of his most notable works are the Portland Building in Oregon, the Steigenberger Hotel in Egypt, and the Walt Disney World Swan at Walt Disney World. He won the AIA Gold Medal in 2001.
