The school was founded by Walter Gropius in Weimar on 1 April 1919, as a merger of the Grand-Ducal Saxon Academy of Fine Art and the Grand Ducal Saxon School of Arts and Crafts for a newly affiliated architecture department. Its roots lay in the arts and crafts school founded by the Grand Duke of Saxe-Weimar-Eisenach in 1906, and directed by Belgian Art Nouveau architect Henry van de Velde. When van de Velde was forced to resign in 1915 because he was Belgian, he suggested Gropius, Hermann Obrist, and August Endell as possible successors. In 1919, after delays caused by World War I and a lengthy debate over who should head the institution and the socio-economic meanings of a reconciliation of the fine arts and the applied arts (an issue which remained a defining one throughout the school's existence), Gropius was made the director of a new institution integrating the two called the Bauhaus. In the pamphlet for an April 1919 exhibition entitled "Exhibition of Unknown Architects", Gropius proclaimed his goal as being "to create a new guild of craftsmen, without the class distinctions which raise an arrogant barrier between craftsman and artist." Gropius's neologism "Bauhaus" references both building and the Bauhütte, a premodern guild of stonemasons. The early intention was for the Bauhaus to be a combined architecture school, crafts school, and academy of the arts. Swiss painter Johannes Itten, German-American painter Lyonel Feininger, and German sculptor Gerhard Marcks, along with Gropius, comprised the faculty of the Bauhaus in 1919. By the following year their ranks had grown to include German painter, sculptor, and designer Oskar Schlemmer who headed the theatre workshop, and Swiss painter Paul Klee, joined in 1922 by Russian painter Wassily Kandinsky. A tumultuous year at the Bauhaus, 1922 also saw the move of Dutch painter Theo van Doesburg to Weimar to promote "De Stijl" ("The Style"), and a visit to the Bauhaus by Russian Constructivist artist and architect El Lissitzky.
