“It was not arsenic poisoning that killed Napoleon at Saint Helena,” said researchers at the National Institute of Nuclear Physics and the University of Pavia who tested the theory the British killed him while he was in exile on the South Atlantic island in 1821.

The Italian research — which studied hair samples from various moments in his life which are kept in museums in Italy and France — showed Napoleon’s body did have a high level of arsenic, but that he was already heavily contaminated as a boy.
