It is perhaps indicative of the differing receptions to and estimations of design in the former West Germany and the former East Germany that while Dieter Rams’ Ten Principles of good design are revered as if cast in stone, Karl Clauss Dietel’s Five Big Ls of good design have barely seen the light of day since November 1989. A popular focus on the former West which tends to popular understandings of design from West Germany as being valid and authentic and laudable, while design from East Germany is reduced, denigrated, to cartoon Ostalgie. With karl clauss dietel. die offene form Walter Scheiffele and Steffen Schuhmann allow one to approach more probable understandings both of the (hi)story of design in the former East Germany and of Karl Clauss Dietel’s position in the (hi)story of design, and in doing so stimulate a re-evaluation of the receptions to and estimations of design in and from East Germany
