Modern architecture and design took shape in the inter-war period in a German school of Arts and crafts. Directed by the architect Walter Gropius during its first decade, the Bauhaus began its trajectory in 1919 in the city of Goethe, in the provincial Weimar, it experienced its most influential period after it was moved to Dessau, an industrial area where Gropius himself built the emblematic premises, and finalized its route in Berlin, closured by the nazi party that reached power in 1933. The greatest artists, photographers, industrial, graphic and furniture designers passed through its workshops and studies, as well as some of the architects that founded modernity.
Paul Klee incorporated into Bauhaus un 1920, and remained there until 1931, so he experienced both, the most enlightened period of the school —catalyzed by the mystical tendencies of the also Swiss-born Johannes Itten—, and the most rationalist and functional period that began in 1923 under the influence of Van Doesburg and the Dutch Neoplasticism. In the company of his close colleague Wassily Kandinsky, but also of Andreas Feininger, Oskar Schlemmer, Herbert Bayer, Marcel Breuer, Laszlo Moholy-Nagy or the Albers marriage (and of course, of the directors that followed who were also architects: Gropius, Hannes Meyer and Mies van der Rohe), the introverted Klee was part of a pedagogic experience that would transform the contemporary visual culture, and, though the forced exile in the USA of many of its protagonists —Gropius, Mies, Moholy-Nagy, Breuer, Albers— would also disseminate the proposals, transformed into the "Bauhaus style", thoughout the Western world.
