Robert Venturi (1925–2018) revolutionized postmodern architecture with his theoretical and built works that challenged modernist simplicity. His book Complexity and Contradiction in Architecture (1966) rejected strict functionalism, advocating for historical references, ornamentation, and playful ambiguity. His firm, Venturi, Scott Brown and Associates, designed notable projects like the Vanna Venturi House, the Seattle Art Museum, and the Sainsbury Wing at the National Gallery, London. Awarded the Pritzker Prize (1991), Venturi’s influence reshaped urban design, architectural criticism, and the postmodern movement, proving that architecture can be both meaningful and delightfully unconventional.
