SS-Leitheft ("SS-lead-booklet") was a Nazi periodical from 1934 to 1945. This "SS-leadership magazine", as it is often called, was published in German in Berlin from 1934 onward, and in the beginning mostly circulated among professional officers in the SS. The publisher was the SS-Hauptamt, the Main Office of the Reichsführer-SS Heinrich Himmler, and the printing was done by M. Müller and Sohn in Berlin. The periodical's spiritual leader was Dr. Franz Riedweg, a Swiss physician who had joined the SS and become the head of Germanic Volunteer Recruiting, a division of the Berlin Main SS-Office.
