The position of SA-Stabschef, not yet a rank, was established in 1929 to assist the Oberste SA-Führer (Supreme SA Leader)[2] with the administration of the fast-growing organization. Otto Wagener held the office under Oberste SA-Führer Franz Pfeffer von Salomon from 1928-1930, and effectively headed the SA from Hitler's assumption of the title Oberste SA-Führer in August until Ernst Röhm replaced him in January 1931.[3]
