Architect Hannes Meyer made substantial changes to the Bauhaus educational programme, reshaping it in response to the crisis created by Walter Gropius’s concept of a new unity of art and technology. From 1928 to 1930, as director at the Dessau Bauhaus he brought in fresh disciplines backed by new appointments and guest instructors. He geared the design process to concrete social problems and incorporated the latest scientific methods. He successfully innovated the realization of building projects and industrial products together with his students.
