 Schreck, a founding member of the SA and a close confidant of Hitler, became the first SS chief in March 1925. On 15 April 1926, Joseph Berchtold succeeded him as chief of the SS. Berchtold changed the title of the office to Reichsführer-SS (Reich Leader-SS). Berchtold was considered more dynamic than his predecessor, but became increasingly frustrated by the authority the SA had over the SS. This led to him transferring leadership of the SS to his deputy, Erhard Heiden, on 1 March 1927. Under Heiden's leadership, a stricter code of discipline was enforced than would have been tolerated in the SA.
