Short answers, pulled from the story.
Adolf Hitler died by a self-inflicted gunshot wound, presumably to his right temple, in the Führerbunker in Berlin on the 30th of April 1945. His wife Eva Braun died at the same time by cyanide poisoning. Their bodies were subsequently burned in the garden of the Reich Chancellery.
Hitler's valet Heinz Linge identified the weapon as a Walther PP or PPK, while adjutant Otto Günsche specified it was the latter. The pistol was found lying at Hitler's feet, and Günsche testified that blood was dripping from Hitler's right temple.
In accordance with Hitler's prior instructions, his and Eva Braun's bodies were carried to the garden of the Reich Chancellery and burned with petrol. By approximately 18:30 on the 30th of April, the remains had been reduced to charred bones and ash, which were covered in a shallow bomb crater.
West Germany issued a death certificate for Hitler on the 25th of February 1956, following four years of court proceedings in Berchtesgaden during which 42 witnesses were interviewed. The certificate was accompanied by a report of more than 1,500 pages.
In 2009, University of Connecticut archaeologist Nick Bellantoni examined a skull fragment the Soviets believed belonged to Hitler, and DNA testing confirmed it was that of a woman. Separately, in 2025, blood from Hitler's sofa was confirmed to be his by comparison with a relative who shared paternal ancestry.
Historians have largely concluded the Soviet Union, under Stalin, ran a deliberate disinformation campaign. On the 5th of June 1945 the Soviets claimed Hitler died of cyanide; four days later they said he had likely escaped. When asked in July, Stalin said Hitler was living in Spain or Argentina. The 1947 book Who Killed Hitler? alleged Soviet leadership kept the question open to motivate its forces against fascism.
