![Hermann Glöckner - Black Red Interlocking [1971]](http://c4.staticflickr.com/9/8275/29611462371_a9a141633e_b.jpg)
Hermann Glöckner (Cotta, January 21, 1889 - Berlin, May 25, 1987) was a German painter and sculptor. He was an important representative of constructivism. In 1932 he became a member of the re-founded Dresdner Sezession. The Nazis refused him any opportunities to exhibit and sell his paintings and graphics. So he turned to sgraffito to earn his living. Glöckner lost his home during Bombing of Dresden in World War II and moved to Loschwitz. Because of his formalist style, the officials of the GDR refused him the appreciation he deserved for a long time. His rehabilitation began with an exhibition of his graphical work in the Kupferstichkabinett, Dresden in 1969.
