Richard Elliott Neustadt (June 26, 1919 – October 31, 2003) was an American political scientist specializing in the United States presidency. He also served as adviser to several presidents.
Neustadt was born in Philadelphia of a family of Swiss origin. Neustadt received a BA in History from the University of California, Berkeley in 1939, followed by an M.A. degree from Harvard University in 1941. After a short stint as an economist in the Office of Price Administration, he joined the U.S. Navy in 1942, where he was a supply officer in the Aleutian Islands, Oakland, California, and Washington. He then went into the Bureau of Budget (now known as the Office of Management and Budget) while working on his Harvard Ph.D., which he received in 1951.
Neustadt died in London after complications from a fall. In addition to Shirley Williams, Neustadt left a daughter, Elizabeth, and a granddaughter. His son, Richard, predeceased him in 1995.
