Throughout his lifetime, the German-Jewish poet Ernst Lissauer (1882–1937) characterized himself as exclusively “German” and was attacked for this by anti-Semites and Zionists alike. The study examines his position between “Germanness” and “Jewishness” and the basic tenets of his works. The analysis is enhanced by the commented edition of his 1935–1937 correspondence with Walter A. Berendsohn.
