Julius Streicher (12 February 1885 – 16 October 1946) was a prominent Nazi prior to World War II. He was the founder and publisher of Der Stürmer newspaper, which became a central element of the Nazi propaganda machine. His publishing firm also released three anti-Semitic books for children, including the 1938 Der Giftpilz ("The Toadstool" or "The Poison-Mushroom"), one of the most widespread pieces of propaganda, which purported to warn about insidious dangers Jews posed.
