Hitler wasn't exactly a genius, but he was a great speaker, one of the best(Just not a good guy). On other people's lists, you meantion people that aren't super smart, but are great speakers. They come off the tongue smart that way.

Anyways, I heard Einstein used like 17% of his brain, normal people now use like under 10%. I heard that he had the most almost ever. And the person with the highest IQ in the world is a woman (Or was a woman).
