Theodor Eicke
Deubel was an inspector at Dachau concentration camp in 1934 when commandant Theodor Eicke was promoted to a role overseeing all concentration camps. Deubel, by then an Oberführer in the SS, was nominated by Eicke as his successor. Deubel commanded the camp from 1 May 1934 until 20 April 1936 with detainees describing his regime as fairly liberal, especially when compared to that of his successor in the role, Hans Loritz.
