Scientists want Hitler conspiracy theories to end because they've now proved he's dead

Scientists say they finally have definitive proof Adolf Hitler did not escape Germany at the end of World War II, and it's time for the conspiracy theories to stop.

A French team of scientists had access to the dictator's skull and fragments of his teeth, and say there is no doubt he died from the effects of both a gunshot to the head and cyanide.

"We can stop all the conspiracy theories about Hitler," says Professor Philippe Charlier of Paris Descartes University.

"He did not flee to Argentina in a submarine; he is not in a hidden base in Antarctica or on the dark side of the moon."

Rumours the Nazi leadership fled to Argentina as the Allies and Russia overran Berlin have persisted for decades. Last month, the wreckage of a technologically advanced WWII German submarine that left Germany two days before the war ended was found at the bottom of the North Sea.

"After the war, there were many rumours about top Nazis who fled in U-boats and brought Nazi gold to safety, and the U-3523 fed the rumours," the Sea War Museum Jutland in Denmark said in April.

"But nobody knows if this was the U-boat's destination, and nobody knows if the U-boat had valuables or passengers aboard in addition to the 58 crew, all of whom perished."

But the new research, published in the European Journal of Internal Medicine, says there's no doubt the skull belongs to Hitler and he is very much dead.

The skull contains a bullet hole, its shape matches radiography scans of Hitler's skull done a year before he died, and the teeth have no traces of meat fibre - Hitler was a vegetarian.

The teeth also have bluish deposits, likely caused by a "chemical reaction between the cyanide and the metal of the dentures" the Fuhrer wore.

"Our study proves that Hitler died in 1945," says Prof Charlier.

Hitler's survival has been the subject of much speculative fiction, most notably The Man in the High Castle - first a novel by sci-fi author Philip K Dick, and presently an Amazon TV series.
