From 1926 until 1932 Mies van der Rohe was vice president of the Deutsche Werkbund, an association of designers and architects whose principal aim was the development of well-designed, mass-producible architecture and household objects by way of an alliance of art and industry. In 1927 the Werkbund presented the influential exhibition "Die Wohnung" (The Dwelling), which included the Weissenhof Siedlung (Weissenhof Housing Estate), an experimental group of model apartment buildings built in a suburb of Stuttgart. Under Mies van der Rohe's direction, a number of important architects, including Mart Stam and Marcel Breuer, collaborated on the project, designing furniture for the apartments. This graceful, elegant, and beautifully proportioned "MR" chair, developed from a 1924 design for a cantilevered chair by Mart Stam, was introduced by Mies van der Rohe at the 1927 Stuttgart exhibition and has remained in production ever since.
Mies van der Rohe was the last director of the Bauhaus design school in Dessau, from 1930 until its closing in 1932. In 1938 he left Germany for America, where he headed the architecture department at the Illinois Institute of Technology.
