Galerie Nierendorf

Karl Nierendorf became an American citizen and the gallery grew, especially with emigre artists such as Lyonel Feininger, Kandinsky, and Klee.

He also helped emerging American artists such as Perle Fine, Adolph Gottlieb, and Louise Nevelson.

[10] In 1963 the gallery, art publisher and art dealer moved to Hardenbergstraße 19 in Berlin-Charlottenburg, where it still exists today as Galerie Nierendorf under the leadership of Ergün Özdemir-Karsch, Florian Karsch's adoptive son.

The artists represented by the gallery include not only those mentioned above, but also representatives of Expressionism and Classical Modernism such as Ernst Barlach, Max Beckmann, Marc Chagall, Lovis Corinth, Gerhard Marcks, Otto Mueller, Hannah Höch and Christian Rohlfs, but also contemporary artists like Louise Christine Thiele.

In 1995 the Karsch couple donated half of their collection to the Berlinische Galerie, including the graphic work by George Grosz.
