20074 Laskerschueler           Discovered 1994 Jan. 14 by F. Borngen at Tautenburg.
German authoress Else Lasker-Schueler (1869-1945) is a representative of expressionism who used in her poems pictures of oriental tales and Old Testament themes. The friendly rapprochement of Jew and Christian was a real concern to her. Beaten by brownshirts in a Berlin street in 1933, she subsequently lived in exile.
