Erhard Milch
Throughout the history of Nazi Germany, the "Luftwaffe" had only two commanders-in-chief. The first was Hermann Göring, with the second and last being "Generalfeldmarschall" Robert Ritter von Greim. His appointment as commander-in-chief of the "Luftwaffe" was concomitant with his promotion to "Generalfeldmarschall", the last German officer in World War II to be promoted to the highest rank. Other officers promoted to the second highest military rank in Germany were Albert Kesselring, Hugo Sperrle, Erhard Milch, and Wolfram von Richthofen.
