Rutgers alumni have been influential in many fields. Singer, athlete, attorney, and Civil Rights Movement activist Paul Robeson graduated in 1919 and is the namesake of the Paul Robeson Cultural Center on the Busch Campus. Among the first students enrolled at Rutgers (when it was "Queen's College"), Simeon De Witt (A.B. 1776) became the Surveyor-General for the Continental Army (1776–1783) during the American Revolution and classmate James Schureman (A.B. 1775), served in the Continental Congress and as a United States Senator. Two alumni have been awarded Nobel prizes— Milton Friedman (A.B. 1932) in economics, and Selman A. Waksman (B.Sc. 1915, M.Sc.1916) in Medicine. Poet Robert Pinsky (B.A. 1962) was appointed the nation's poet laureate and novelist Junot Díaz (B.A. 1992) awarded the Pulitzer Prize for Fiction in 2008.
