Johann Andreas Eisenmenger

Johann Andreas Eisenmenger (1654, Mannheim – 20 December 1704, Heidelberg) was a German orientalist scholar from the Electorate of the Palatinate, now best known as the author of ''Entdecktes Judenthum'' (''Judaism Unmasked''), which was published in two volumes in 1711 and 1714.

In this work, Eisenmenger sought to expose the allegedly secret and nefarious practices of Jews, and he claimed that Judaism was a false religion that had been invented by the ancient Israelites in an attempt to deceive the world.

Financier Samuel Oppenheimer, one of the most influential Jewish members of the Court of the House of Habsburg, fearing that the book's publication would give additional strength to the prejudice against them, denounced it as a malicious libel, and tried to have the work banned. He failed, but subsequently his rival, the financier and rabbi Samson Wertheimer successfully petitioned Emperor Leopold I to have the book banned.

His work was widely read and had a significant influence on European attitudes toward Jews in the 18th and 19th centuries. It is considered an early example of modern anti-Semitism and played a role in shaping the negative stereotypes and prejudices that were held against Jews in Europe at the time. Despite being debunked by scholars, his work remains a controversial and influential text in the history of anti-Semitism. Provided by Wikipedia
