Adolf Hitler
The man who terrorized the world was afraid of dentists, obsessed with pastries, and spent his final years dosing himself with a cocktail of drugs that included cocaine eye drops and bull testicle extract.
Adolf Hitler's daily routine in the bunker beneath Berlin revealed a man whose grip on reality had long since snapped. He woke at noon, spent hours studying architectural models of cities he planned to rebuild after winning a war he'd already lost, and insisted on tasting every meal before his dog Blondi ate — not from paranoia about poison, but because he'd convinced himself that animals could detect inferior ingredients. His physician, Theodor Morell, administered up to twenty-eight different medications daily, including a preparation called "Vitamultin" that was essentially methamphetamine mixed with vitamins.
The dictator who preached Aryan supremacy was terrified of germs, refused to shake hands without gloves, and had his uniforms burned after every public appearance. He ate the same meal — vegetable soup, mashed potatoes, and cake — for dinner every night, prepared by a chef who had to sign a death oath promising never to reveal the recipes. When his dentist Hugo Blaschke finally examined his rotting teeth in 1944, he found a mouth so diseased that Hitler could barely chew solid food, explaining his liquid diet and the slurred speech that had become increasingly noticeable in his final broadcasts.
Perhaps most telling was his obsession with his nephew William Patrick Hitler, who had emigrated to America and joined the U.S. Navy. Hitler kept a detailed file on William's movements and reportedly offered him a high position in the Nazi hierarchy to return to Germany. When William refused, Hitler had his name legally changed and tried to have him assassinated — twice. The Führer who claimed to embody the destiny of the German people spent his last months fixated on a family member who was dropping depth charges on German submarines in the Atlantic.
Hitler's final meal was spaghetti with tomato sauce, which he ate while dictating his last will and testament — a document that spent more words complaining about his architect's building delays than addressing the collapse of Nazi Germany.
Why untold: The focus on Hitler's political crimes has overshadowed the detailed documentation of his bizarre personal habits and medical records, which reveal the extent of his psychological and physical deterioration.
