Despite his death 70 years ago, Adolf Hitler continues to spark controversy. Inexplicably der Führer advanced by a year or two the long-planned German invasion of the Soviet Union (Operation Barbarossa). He also instigated a baffling delay for reinforcing the beleaguered German defenders on D-Day. These strategic errors ultimately cost Germany the war. This class will consider these military blunders in light of Hitler’s ticking sense of his approaching mortality due to his neurological and cardiac disease. Medical evidence will demonstrate a negative impact existed on his decision-making abilities fashioned by his life-shortening Parkinson’s disease with its associated behavioral changes and by his progressive, largely untreatable at the time, coronary artery disease.
