Robert Venturi exploded onto the architectural scene in 1966 with a radical call to arms in Complexity and Contradiction. Further accolades and outrage ensued in 1972 when Venturi and Denise Scott Brown (along with Steven Izenour) analyzed the Las Vegas strip as an archetype in Learning from Las Vegas. Now, for the first time, these two observer-designer-theorists turn their iconoclastic vision onto their own remarkable partnership and the rule-breaking architecture it has informed. The views of Venturi and Scott Brown have influenced architects worldwide for nearly half a century. Pluralism and multiculturalism; symbolism and iconography; popular culture and the everyday landscape; generic building and electronic communication are among the many ideas they have championed. Here, they present both a fascinating retrospective of their life work and a definitive statement of its theoretical underpinnings. Architecture as Signs and Systems is aimed at students of architecture and urban planning, as well as anyone intrigued by these seminal cultural figures. Venturi and Scott Brown have devoted their professional lives to broadening our view of the built world and enlarging the purview of practitioners within it. By looking backward over their own life work, they discover signs and systems that point forward, toward a humane Mannerist architecture for a complex, multicultural society.
