Robert Charles Venturi Jr. (June 25, 1925 – September 18, 2018) was an American architect, founding principal of the firm Venturi, Scott Brown and Associates, and one of the major architectural figures of the twentieth century. Together with his wife and partner, Denise Scott Brown, he helped shape the way that architects, planners and students experience and think about architecture and the built environment. Their buildings, planning, theoretical writings, and teaching have also contributed to the expansion of discourse about architecture.
