New life for American Downtowns? The 1958 international seminar on urban renewal and the travel of planning ideas in the North Atlantic World

This article scrutinizes the travel of planning ideas between Western Europe and America in the post-war decades by employing the 1958 International Seminar on Urban Renewal as a case study. As a joint venture between the International Federation for Housing and Planning and James M. Miller, a planning professor from Columbia University, this meeting was the first transatlantic conference after 1945 principally intended to (re-)introduce American planners to European reconstruction efforts. Therefore, the seminar testifies to an emerging interest of the wider US professional public in West European planning during the 1950s. When American planners struggled with deteriorating downtowns and suburbanization, they turned to Europe, where cities experimented with pedestrianization, mixed-use zoning and comprehensive planning in order to build their razed city centres anew. Although Americans were relatively unsuccessful in implementing these ideas in their cities, the events surrounding the 1958 seminar show that, even during a period of US hegemony, transatlantic connections were more than a mere 'Americanization' of European practice. Thus, this article argues for viewing transnational connections in the post-war North Atlantic World as a circular flow of ideas, in which Europeans and Americans alternately acted as borrowers and lenders, according to their variable perceptions of each other.
