Hersteller / Manufacturer.
Founded in 1817 by Georg Friedrich Horn as an earthenware factory, although he advertised it as a "Porcelain Factory" and subsequently a "Stone Porcelain Factory". Georg Friedrich Horn was a tax collector and as such was not allowed to run any company, therefore ownership of the factory was transferred to his two sons around 1822 and  became Gebrüder Horn. In 1906 the name changed to Steingutfabrik Hornberg, Aktiengesellschaft, vormals Gebrüder Horn. In 1907 the name became Schwarzwälder Steingutfabrik, Aktiengesellschaft and run by a Dr. Ehrlich. Again in 1911 the name changed to Steingutfabrik Schwarzwald, G.m.b.H. until at least 1941. In 1912 production of earthenware crockery ceased and in 1956, production moved over entirely to porcelain. 1960 saw the change to a limited company, named Duravit G.m.b.H. Finally in 1988, the company became Duravit AG. Its current production is mainly porcelain bathroom products. Rudolf Ditmar and K. u. K. priviligierte Wilhelmsburger Steingut- und Porzellanfabrik have ended up via the same
Keramik Holding Laufen, in the R.O.C.A. group.
