Best known for his contributions to post-modern architecture, Robert Venturi, in collaboration with his wife Denise Scott Brown, has worked on a number of notable projects, including the Seattle Museum of Art and the Sainsbury addition to the National Gallery in London. Born in Philadelphia in 1925, Venturi attended Princeton University, graduating Summa Cum Laude in 1950. He studied under Eero Saarinen (another architect on our list). In addition to his architectural work, Venturi is also known for his theoretical work, including his 1966 book, Complexity and Contradiction in Architecture, and has won the Pritzker Prize.
