Abstract: | Abstract When Robert Venturi began writing Complexity and Contradiction in Architecture in 1962, Jane Jacobs's The Death and Life of Great American Cities (1961) was the subject of dinner-table conversation across the country. Apart from Jacobs's direct influence, among the parallels that emerged from their Townscape affiliations and other interests, the concept of complexity stands out, with Venturi's conception echoing Jacobs's historic introduction of complexity science into architectural and urban theory. While Venturi did not seek to extend the scientific research put forward by Jacobs, favoring instead the complexities suggested by gestalt theory and New Criticism, he cited similar scientific sources and derived similar principles for urbanism, as revealed by his Copley Square project of 1966. |
