“Adolf Hitler: His Life and Speeches,” was credited to Baron Adolf Victor von Koerber, but recent research indicates Hitler wrote it himself.
von Koerber was a conservative and virulent anti-Semite who initially supported Hitler but later worked against him. The aristocrat was arrested and sent to a Gestapo prison and a concentration camp and passed intelligence to the British.
von Koerber reversed positions in later life, becoming a liberal and even hiding Hermann Ullstein, a liberal Jewish newspaper tycoon and publisher, for whom von Koerber wrote.
