"Publisher of Käthe Kollwitz's Printed Work." Publishing imprint founded in 1931 by art dealer Alexander von der Becke, when he took over the inventory of Käthe Kollwitz's unsold prints as well as her printing plates after the bankruptcy of Galerie Emil Richter, Dresden, which had published Kollwitz's prints from about 1910 to 1930.  Under the Nazi regime, he suffered from declining sales, as Kollwitz experienced increasing difficulty publishing and exhibiting her work. In 1941 the Gestapo closed his business and confiscated his stock. Reestablished in 1946, and subsequently issued posthumous reprints of the thirty Kollwitz etching plates that survived the war (some in need of repair). After his death in November 1958, wife Johanna and son Bernhard continued the business and opened a branch in Munich in 1963, publishing posthumous Kollwitz reprints until 1972."
