Andrew Jackson
Andrew Jackson, with an IQ of 145, believed in the “common man” to “arrive at the right decision.” The old proverb “if it doesn’t kill you, it makes you stronger” definitely rings true for Jackson, who suffered an injury after being shot in the chest during a duel. To put his IQ to use, Jackson spent a lot of time teaching his pet parrot Polly to swear. He trained the bird so well that it had to be removed from its master’s funeral because of its potty mouth.
