Leipzig: Verlag von Gustav Engel, 1926. First edition. Simple half leather binding, with tan leather spine and gilt titles. Marbled boards. The spine is somewhat sun-faded. The interior is in excellent condition. The original yellow soft cover is bound in. Page edges are untrimmed. Clean and tidy throughout. A satire on antisemitism which takes the racial theories developed in the late 19th and early 20th centuries to absurd extremes, set here in the inter-war period; an important historical document of the Weimar Republic era. The first article is a direct attack on the Nazi newspaper Völkischer Beobachter, mocking its attempts to prove that "Jesus was not Jewish" through fanciful etymologies — for example, claiming that the Galileans were "Germanic Gauls," or that the word "Aramaic" derives from "Aryan." The text is organised into a series of short articles in the same satirical spirit, such as "If a Jewish ancestor of Bismarck were to be discovered." "Dr. Mehemed Emin Efendi" was a pseudonym of Siegfried Lichtenstaedter (1865–1942), a German-Jewish administrative lawyer from Baiersdorf, Bavaria, who rose to Oberregierungsrat in the Bavarian civil service before his retirement in 1932. The pseudonym did not protect him: under the Nazi regime his pseudonymous writings were identified via the "Judenkartei" (Jewish card index), and in 1938 Antisemitica appeared on the list of harmful and undesirable literature. He was deported from Munich to the Theresienstadt ghetto on 25 June 1942, where he died on 6 December of that year. His work has since been rediscovered, notably through historian Götz Aly's edited volume Siegfried Lichtenstaedter: Prophet der Vernichtung ("Prophet of Annihilation"). 126 pages, with a ten-page catalogue of Gustav Engel publications to the rear. 220 by 140mm (8¾ by 5½ inches). Although a number of library holdings exist, no copies of the first edition were found for sale at the time of cataloguing.
