Maurice Joly  

Seven years after the publication of Sue's Les Mystères du peuple, a French revolutionary named Maurice Joly plagiarized aspects of the work for his anti-Napoleon III pamphlet, Dialogues in Hell between Machiavelli and Montesquieu, which in turn was later adapted by the Prussian Hermann Goedsche into an 1868 work entitled Biarritz, in which Goedsche substituted Jews for Sue's infernal Jesuit conspirators. Ultimately, this material became incorporated directly into the notorious anti-Semitic hoax, The Protocols of the Elders of Zion.
