The Bauhaus Archive / Museum of Design in Berlin engages in the research and presentation of the history and influence of the Bauhaus (1919-1933), the most important school of architecture, design and art in the twentieth century. The entire spectrum of the school's activities is represented in the Bauhaus Collection: architecture, furniture, ceramics, metalwork, photography, stage pieces and student work from the preliminary course, as well as works created by the school's famous teachers, including Walter Gropius, Johannes Itten, Paul Klee, Lyonel Feininger, Wassily Kandinsky, Josef Albers, Oskar Schlemmer, László Moholy-Nagy and Ludwig Mies van der Rohe. Even today, the "Bauhaus Lamp", the "Wassily" armchair, Bauhaus wallpaper and other pieces are regarded as modern classics. This presentation of paintings, drawings, sculptures and models by Bauhaus masters and students from the world's largest collection of Bauhaus artefacts illustrates its lasting influence. Researchers have access to over 28,000 volumes (books, periodicals, exhibition catalogues) on the history and reception of Bauhaus ideas and activities in the library. The document collection contains manuscripts, letters, printed matter, drawings, plans and photos, as well as the Gropius Estate. The programme of the museum is complemented by at least four special exhibitions, numerous lectures, podium discussions, workshops, readings and concerts.
