Presents a cultural history of German Jewry from Moses Mendelssohn's arrival in Berlin until the end of the Weimar Republic. Refers to antisemitism in a number of contexts: Mendelssohn is hailed by German intellectuals as an exception among the Jews; acceptance of the Jew was sometimes soon followed by rejection; despite or because of disproportionate Jewish contributions to culture and society, Jews are viewed as foreigners; rights are granted only to rich and useful Jews; despite Jewish patriotism, Jews are often portrayed as traitors and subversives. Among the prominent Jews discussed are Heinrich Heine, whose ambivalence toward Germans reflected their ambivalence toward him, and Walther Rathenau who was assassinated by radical nationalists whose activities the Weimar Republic was unable to curb. The section devoted to the latter reveals how Weimar's weaknesses opened the door of power to the Nazis.
