Gropius is renowned as a pioneering architect and as a highly influential figure in design education. Working for Behrens, he met Mies and possibly Corbusier (later, a colleague at CIAM). Van de Velde wanted him to take over his own position in Weimar. Klee, Kandinsky, Itten and Moholy-Nagy were all recruited by Gropius to the Bauhaus (he rejected van Doesburg), where Mies, Breuer, Schlemmer and Josef Albers all became key colleagues. Stravinsky (a Bauhaus supporter) and Moore were among a wide circle of friends. Sert succeeded him at Harvard. Mahler protested to Gropius about his affair with his wife, unavailingly.
