Hans-Joachim Neumann and Henrik Eberle, a historian and a physician, list 82 drugs taken by Hitler, including sedatives, analgesics, stimulants, laxatives, painkillers and much besides. His constant speechifying, especially during the election campaigns before he came to power, caused a hoarseness that was cured in April 1932 after voice training from the celebrated tenor Paul Devrient. The hoarseness returned in 1935, leading Hitler to fear that he had throat cancer and fuelling anxieties about his own mortality that led him to adopt a more aggressive foreign policy over the next four years. In August 1941, Hitler contracted dysentery, which knocked him out for a fortnight, but it didn’t affect the course of the war, since he soon resumed command of the armed forces and issued the fateful order to divert a significant portion from the attack on Moscow to the invasion of the Ukraine. He was taking 28 pills a day by the last months of the war. He also had problems with his teeth.
