The work of architect, exhibition designer, and university lecturer Karl Otto (1904-1975) exemplifies artistic ambitions and societal debates in the early years of post-war German modernism. Otto was a student of Hans Poelzig and a collaborator of Ludwig Mies van der Rohe. His work was influenced by the ideals of the German Werkbund, the Bauhaus, and the New Building movement. Fabian Ludovico comprehensively documents the various fields of activity of Karl Otto for the first time, examines connections, and highlights areas of tension. The biography of the architect and the first complete catalog of his works help answer the central question: How are Karl Otto's artistic and civic educational aspirations reflected in his overall body of work? The focus is on the 1950s, particularly in the conception of two of the works.
