Robert Ritter von Greim
Robert Ritter von Greim was a German Generalfeldmarschall and First World War flying ace. In April 1945, in the last days of World War II in Europe, Adolf Hitler appointed Greim commander-in-chief of the Luftwaffe after Hermann Göring had been dismissed for treason. He is the last person ever promoted to field marshal in the German armed forces. After the surrender of Nazi Germany in May 1945, Greim was captured by the Allies. He committed suicide in an American-controlled prison on 24 May 1945.
