The Käthe-Kollwitz-Museum Berlin is a Berlin museum entirely dedicated to the work of one of the most famous Berlin artists, Käthe Kollwitz (1867-1945). Käthe Kollwitz is best known for her studies of characters in pure expressionist style and for her representations of human torment. He lived and worked in the Prenzlauer Berg district, at that time a working-class district, for more than fifty years, between misery and poverty. Opened in 1986, the museum is housed in an old and elegant town house from the second half of the 19th century. Its origins are due to the collector Hans Pels-Leusden, who since 1950 had begun to collect the artist's works, creating the first exhibition dedicated to her in 1965. The collection consists of over 200 prints, lithographs, woodcuts, and sculptures. Among these, the famous manifesto of the "Nie wieder Krieg" (no more war - 1924), the lithograph "Brot" (bread - 1924) against hunger, and the Memorial to Karl Liebknecht, a socialist revolutionary murdered in Berlin in 1919. Of particular interest are his self-portraits, as well as the woodcuts of the Guerra series (1922-23) and the cycle of eight lithographs entitled "Death", a theme on which the artist periodically returned until 1942. Among the recurring subjects of Käthe Kollwitz there is also motherhood, works born from the premature loss of the second child Peter and a grandson during the Second World War. Opposed by the Nazis, in 1933 Käthe Kollwitz was removed from her post as a teacher of graphic arts at the Prussian Academy and from 1936 she was forbidden to exhibit her works, which disappeared from every gallery. The museum also organizes temporary exhibitions on a regular basis.
