"This is what has Gropius the director made the w:Bauhaus famous. Not its lamps or its furniture. They are all out of fashion already. But the way of approaching formal problems or material as such, that has made it famous. And the emphasis on material, especially its capacity is my contribution. That was never cleared between us teachers: Kandinsky did what he thought should be done. Klee developed an absolutely different method. Schlemmer developed absolutely something else."
