Peter Deeg (14 May 1908 – 25 June 2005) was a German lawyer, writer and politician. He was a member of the NSDAP and later the Christian Social Union of Bavaria.
Peter Deeg was born in Bad Kissingen. He was a NSDAP party-member since the year 1928. He became famous in connection with the so-called "Mordfall von Waltershausen" (Murder of Waltershausen), with a spectacular court hearing in 1933. This conflict has an antisemitic background. Because of the contact to important lawyers, he came in contact with Julius Streicher, who became his mentor.
Julius Streicher allowed Deeg to publish his books in the NSDAP publishing house Der Stürmer. Between 1938 and 1940, three famous books were published: Hofjuden (Court Jew), Die Judengesetze Großdeutschlands (Jewish laws of Großdeutschland), Vor 50 Jahren. Für und wider den Russen-Pakt (50 years ago – pro or against the pact with Russia). Since 1940, Deeg seemed to be in conflict with the NSDAP. But this part of his life is not very clear.
After World War II, Deeg became a close friend to Franz Josef Strauss. Together with him, he was a part of the Spiegel scandal.
