Marr was born in Magdeburg as the only son of an actor and stage director. He went to a primary school in Hannover, then to a high school in Braunschweig. In Hamburg and Bremen he was an apprentice in commerce, then he joined his father in Vienna, who had been engaged by the Burgtheater. There he worked as an employee in two Jewish firms. He later claimed that he had unjustly lost his job.
In 1841 he went to Zurich, where he became acquainted with political émigrés (like Georg Herwegh, Julius Fröbel, and August Follen), most of them members of the democratic or liberal leftist movements of the early 19th century.
In 1843 Marr was expelled from Zurich under the accusation that he had furthered communist activities. He turned to Lausanne, where he joined Hermann Döleke and Julius Standau, the founders of the secret Léman-Bund, which belonged to the "Junges Deutschland" (Young German Movement). Marr eventually became the head of the secret society and began to lean towards anarchism and atheism, founded another secret society, the "Schweizerischer Arbeiterbund" (Swiss Worker's Union) and edited the "Blätter der Gegenwart für sociales Leben" (Present-Day Papers for Social Life, 1844/45). In 1845 he was expelled from Lausanne, too, and went to Hamburg. There he became a political journalist and published the satirical magazine "Mephistopheles" (1847/48-1852). He belonged to the leftists of the radical-democratic "party" and was a delegate to the National Assembly in Frankfurt after the March-Revolution of 1848. After the ultimate failure of the revolution he - like so many other former revolutionaries - became a proponent of the idea of German unification under Prussian leadership.
In Marr went abroad, to Costa Rica, where he tried to make a living as a businessman. Lacking success he returned to Hamburg, worked again as a journalist, and in 1854 he married Georgine Johanna Bertha Callenbach, daughter of a Jewish businessman who had renounced his faith. The couple was divorced in 1873. In 1874 Marr remarried the Jewish Helene Sophia Emma Maria Behrend, who died within the same year. In 1875 there was a third marriage, with Jenny Therese Kornick (whose parents lived in a Christian-Jewish mixed marriage), who bore him a son. In 1877 this marriage was divorced, too; Marr's last wife was Clara Maria Kelch, daughter of a Hamburg working man.
Marr's speeches and articles showed first indications of antisemitism in 1848. He was influenced by the Burschenschaft movement of the early nineteenth century, which developed out of frustration among German students with the failure of the Congress of Vienna to create a unified state out of all the territories inhabited by the Volk. The latter rejected the participation of Jewish and other non-German minorities as members, "unless they prove that they are anxious to develop within themselves a Christian-German spirit" (a decision of the "Burschenschaft Congress of 1818"). While they were opposed to the participation of Jews in their movement, like Heinrich von Treitschke later, they did allow for the possibility of the Jewish (and other) minorities participating in the German state if they were to abandon all signs of ethnic and religious distinctiveness and assimilate completely into German Volk.
Marr took these philosophies one step further by rejecting the premise of assimilation as a means for Jews to become Germans. In his pamphlet Der Weg zum Siege des Germanentums über das Judentum (The Way to Victory of Germanicism over Judaism, 1879) he introduced the idea that Germans and Jews were locked in a longstanding conflict, the origins of which he attributed to race — and that the Jews were winning. He argued that Jewish emancipation resulting from German liberalism had allowed the Jews to control German finance and industry. Furthermore, since this conflict was based on the different qualities of the Jewish and German races, it could not be resolved even by the total assimilation of the Jewish population. According to him, the struggle between Jews and Germans would only be resolved by the victory of one and the ultimate death of the other. A Jewish victory, he concluded, would result in finis Germaniae (the end of the German people). To prevent this from happening, in 1879 Marr founded the League of Antisemites (Antisemiten-Liga), the first German organization committed specifically to combating the alleged threat to Germany posed by the Jews and advocating their forced removal from the country.
Although he had introduced the pseudo-scientific racial component into the debate over Jews in Germany, it is unlikely that he was influenced by the earlier theories of Arthur de Gobineau (author of An Essay on the Inequality of Human Races, 1853), who was only translated into German in 1898, a quarter of a century after Marr's pamphlet appeared. It is, however, highly probable that Marr was able to read Gobineau in French. Furthermore, Marr himself was very vague about what constituted race and, in turn, the racial differences between Jews and Germans, though this became a feature of Nazi racial science. It remained for later racial thinkers to postulate specific differences: these included Eugen Dühring, who suggested that it was blood, and Houston Stewart Chamberlain, an influential race theorist and husband of Eva Wagner, Richard Wagner's daughter, who suggested phrenology as a means of distinguishing races.
Despite his influence, Marr's ideas were not immediately adopted by German nationalists. The Pan-German League, founded in 1891, originally allowed for the membership of Jews, provided they were fully assimilated into German culture. It was only in 1912, eight years after Marr's death, that the League declared racism as an underlying principle. Nevertheless, Marr was a major link in the evolving chain of German racism that erupted into genocide during the Nazi era.
Renunciation of Antisemitism
Toward the end of his life Marr came to renounce anti-semitism, arguing that social upheaval in Germany had been the result of the Industrial Revolution and conflict between political movements. According to Moshe Zimmermann he "openly requested the Jews' pardon for having erred in isolating the problem". He published in Hamburg a final essay entitled Testament of an Antisemite in which he explained the history of his thinking, asserting that he had originally been a "philo-Semite", having rejected "the miserable Romantic madness of Germanism". He complained that modern anti-Semitism was becoming merged with German mysticism and nationalism. Marr condemned 'the beer drinking leaders, the gay "Heil" shouters of modern anti-Semitism' and crude prejudice against Jewish writers and thinkers.
