Since the 1920s, Wolfgang von Wersin (1882-1976) was responsible for the design of the products of the metal ware factory Erhard & Söhne in Schwäbisch Gmünd, like in the Deutschen Werkstätten Hellerau. His design-work was interrupted by the World War II, then picked up 1938 again until 1959. With the thermos flask Wersin succeeded in the area of the metalworking. He began with the planning in the year 1956. The clear balanced form correspond not only the optical reception of individual parts of the mug but also the production-technical necessities. The ideals of the German Werkbund (membership since 1913) are represented here in the best way. Since 1975, the mug is copieed through other companies.
