In March 1968, Robert Venturi, writer of
Complexity and Contradiction in Architecture, and Denise Scott Brown wrote and published "A Significance for A&P Parking Lots, or Learning from Las Vegas" (
Architectural Forum, March 1968). That following fall, the two created a research studio for graduate students at
Yale School of Art and Architecture. The studio was called "Learning from Las Vegas, or Form Analysis as Design Research". Izenour, a graduate student in the studio, accompanied his senior tutor colleagues, Venturi and Scott Brown, to
Las Vegas in 1968 together with nine students of architecture and four planning and graphics students to study the urban form of the city. Las Vegas was regarded as a "non-city" and as an outgrowth of a "strip", along which were placed parking lots and singular frontages for gambling casinos, hotels, churches and bars. The research group studied various aspects of the city, including the commercial vernacular, lighting, patterns, styles, and symbolism in the architecture. Venturi and Scott Brown created a taxonomy for the forms, signs, and symbols they encountered. The two were inspired by the emphasis on sign and symbol they found on the Las Vegas strip. The result was a critique of Modern architecture, demonstrated most famously in the comparison between the "duck" and "decorated shed." The "duck" represents a large part of modernist architecture, which was expressive in form and volume. In contrast, the "
decorated shed" relies on imagery and sign. Virtually all architecture before the Modern Movement used decoration to convey meaning, often profound but sometimes simply perfunctory, such as the signage on medieval shop fronts. Only Modernist architecture eschewed such ornament, relying only on corporeal or structural elements to convey meaning. As such, argued the authors, Modern buildings became mute and vacuous, especially when built for corporate or government clients. ==Reception==
