Walter Gropius was a German architect and designer and one of the central figures of the Modern Movement. After working with Peter Behrens, he founded the Bauhaus in Weimar in 1919, developing a new approach to design that brought together art, craftsmanship and industrial production. The school brought together some of the most influential figures in twentieth-century art and design, including Wassily Kandinsky, Paul Klee, Marcel Breuer and Ludwig Mies van der Rohe. Gropius later designed the Bauhaus building in Dessau, one of the defining works of modern architecture. After leaving Germany, he moved first to England and then to the United States, where he taught at Harvard and founded The Architects Collaborative. His ideas on the relationship between architecture, design and industry had a lasting influence on twentieth-century design.
