The Lexikon deutsch-jüdischer Autoren (Encyclopaedia of German-Jewish Authors) covers the Jewish contribution to German-speaking cultural history in some 1,300 biographical-bibliographic articles. Besides authors of literature in the broadest sense, representatives of the humanities can be found and other individuals from public life who, through their work, were influential beyond their specialist field: psychologists and psychoanalysts, historians and philosophers, artists, politicians and Rabbis. Authors who published in the German language have been included regardless of their geographical origin. The Lexikon deutsch-jüdischer Autoren documents two hundred years of German-Jewish culture and Germans and Jews living together. This period begins with Moses Mendelssohn (1729-1786) and the beginnings of the Jewish emancipation and ends with the extermination and expulsion of the Jews during the National Socialist era. The encyclopaedia covers individuals who experienced and expressed their Judaism in very different ways: from strict orthodoxy to liberal Judaism and rigorous Zionism.
