Bernard Tschumi is a border crosser in the field of contemporary architecture. Equally present in Europe and the United States, he laid the cornerstone for his influential body of work two decades ago with a project that combines architecture and landscape architecture, theory and practice: the Parc de la Villette in Paris. Dean of the Columbia Graduate School of Architecture in New York for many years and the author of numerous books on architectural theory, Tschumi possesses a body of work that is presented here in overview for the first time. His current projects include a high-rise apartment building in New York, the Zénith Concert Hall in Limoges, and the new Acropolis Museum in Athens. Gilles de Bure, the author of numerous architectural publications on Jean Nouvel, Dominique Perrault, Christian de Portzamparc, and others, presents an in-depth analysis of Tschumis work.
