In a talk given as part of the Summer School schedule, Peter Smithson discusses the Economist Building. Alison and Peter Smithson were among the most influential architects of the postwar decades. Their reevaluation of modernism shifted the focus of architecture and urbanism toward the particularities and uniqueness of human associations, urban patterns, and climatic conditions. Many of their ideas, both social (cluster and human association) and architectural (Brutalism, the nature of materials), profoundly influenced later generations of academics, students, and practitioners. NB: Background noise often makes it difficult to hear Peter Smithson.
