Robert Arthur Morton Stern, usually credited as Robert A. M. Stern, (born May 23, 1939) is an American architect and Dean of the Yale University School of Architecture.
His work is generally classified as postmodern, though a more useful classification would be a particular emphasis on context and the continuity of traditions. He may have been the first architect to use the term "postmodernism", but more recently he has used the phrase "modern traditionalist" to describe his work.
He received a bachelor's degree from Columbia University in 1960 and a master's degree in architecture from Yale University in 1965. After graduating from Yale, Stern worked as a designer in the office of Richard Meier in 1966, prior to forming the firm of Stern & Hagmann with a fellow student from his days at Yale, John S. Hagmann, in 1969. In 1977 he founded the successor firm, Robert A. M. Stern Architects. Before becoming architecture dean at Yale, he was professor of architecture at Columbia and director of Columbia's Temple Hoyne Buell Center for the Study of American Architecture.
