This article demonstrates how anti-Semitism and antimodern anti-Americanism start to intertwine in German-speaking lands, that is more specifically the ‚Deutscher Bund‘ and the ‚Deutsches Reich‘. The study engages with the works of the German economist and sociologist Werner Sombart (1863–1941). His studies are selected mainly because they were very popular in their time. Furthermore, he made use of anti-Semitic and anti-American stereotypes for his argumentation. The article at hand highlights the intricate link between both stereotypes in his surveys. Werner Sombart’s works evoke the impression of balanced academic studies, nevertheless attributing similar characteristics to Americans and Jews. In line with his pseudo-academic approach, he also ventures to justify these specific attributes. On the one hand, he attributes number-based and abstract thinking to Jews as well as Americans. On the other, according to this argumentation, the US were decisively influenced by Jewish immigrants from the beginning. Despite enormous waves of Jewish migration to the US during his lifetime, contemporary American Jews play a minor role in Sombart’s argumentation.
