Walter Gropius ®
According to Walter Gropius, the Gropius handle was made in 1922 in his private workshop in Weimar. At the time, Gropius was director of the State Bauhaus in Weimar. A first variant was used in the conversion of the Stadttheater in Jena and the Otte house in Berlin in the autumn of 1922, as well as in the interior design of the Fagus factory in Alfeld at the end of 1922. In the summer of 1923, the handle was also used in the "Am Horn Experimental House" in Weimar. For the house designed by Georg Muche for the first major Bauhaus show, the door handles and the window handles were created according to the same design principle. The Gropius or Bauhaus handle developed within short time to the most popular lever handle of the new building.
