Deputy Chief, Prussian Secret State Police, II 1 B 2 - J.328/36 II Berlin, 24 April 1936 a) to all State Police Stations b) to all district heads of Prussia c) to all the political police authorities of the federal states (except Prussia). re: prohibition against speeches by Dr. Leo Plauth, born April 29, 1900, in Willinghausen. I am enclosing, for your information, my order prohibiting speeches by Dr. Leo Plauth. The order is to be distributed to all offices under your command. Reasons: in recent meetings of the Central Association of Jews in Germany ( Centralverein ), Plauth proved to be an advocate of assimilation. In his speeches, he attempts - in a disguised form - to induce the Jews to stay in Germany. His activity therefore aims to undermine the measures taken by the Reich government to promote the emigration of Jews.
