Ludwig Mies van der Rohe began his career working in his fathers stonemasonry business. After an apprenticeship with furniture designer Bruno Paul in Berlin, he joined the office of architect Peter Behrens, whose work presaged the modern movement. In 1912, Mies established his own office in Berlin, and later became a member of the Deutscher Werkbund and Director of the Bauhaus. He immigrated to the United States in 1938, setting up a practice in Chicago. His most iconic designs include the Barcelona Chair and Brno Chair.
