Gropius built the Fagus factory at Alfeld in 1911 with Adolf Meyer, hanging glass in front of the structure rather than between piers, and spent the rest of his life arguing the consequences. In 1919 he founded the Bauhaus in Weimar and directed it until 1928, first in Weimar and, from 1925, in the building he designed for it in Dessau. His interest was less a style than a method: workshops rather than ateliers, and a curriculum that put craft training before design. He emigrated to England in 1934 and to the United States in 1937, where he taught at the Harvard Graduate School of Design and co-founded The Architects Collaborative, a practice deliberately organised so that no single name signed the work. He won the Royal Gold Medal in 1956 and the AIA Gold Medal in 1959.
