The rise of political anti-Semitism in Imperial and Weimar Germany met with public opposition initiated primarily by Jews. From various perspectives, jewish journalists and intellectuals investigated the origin of this anti-Semitism, its different manifestations as well as possibilities of its public rejection. Journalist Binjamin W. Segel (1866-1931) hereby focused his efforts on debunking antiSemitic myths, such as the Jewish World Conspiracy, as popularized by the text "The protocols of the Elders of Zion". In his writings, Segel, with an Eastern European background, pays attention to the discrimination of "Ostjuden" (EastEuropean Jews) in particular. Furthermore, Segel deals with questions regarding the origins of anti-Semitism, and the effectiveness of Jewish opposition towards it. The following article outlines his life and discusses his work.
