An ardent exponent of Nazi Racism, claiming scientific grounds for his beliefs and actions: “The blood particles of Jews are completely different from those of a Nordic man.

Streicher was the managing editor of a Nazi propagandist journal Der Stunner (1923-45), was area commander of Franconia, and was hanged as a war criminal.
