Napoleon Bonaparte

Last Wish: That his head be shaved and the hair divided up amongst his friends.

In a strange twist to the tale, a recent analysis some of the hair that was kept by his friends, it was discovered that it contained large amounts of arsenic. His symptoms prior to death (vomiting dried blood) is consistent with arsenic poisoning. There is some speculation that the walls of his room contained arsenic (not uncommon at the time) and that it was his environment that killed him, but others believe that he was being slowly poisoned by the English. In fact, due to his stomach cancer, his doctor was also prescribing him another type of poison which contributed to his final demise.
