Thanks to the Broadway phenomenon Hamilton, a lot more people know the ins-and-outs of the Aaron Burr biography. But is that portrayal of Burr's life even accurate? Who was Aaron Burr, really? Burr is primarily known for his deadly duel with Alexander Hamilton. Yeah, that was a pretty depressing moment in American history: the sitting vice president straight-up murdering a man. But that's just scratching the surface of Burr's bummer of a story. There's a lot to this man beyond the Aaron Burr duel, as the history buffs among you surely know. Be forewarned: you might need a drink after reading some of the most depressing and, in some cases, totally bizarre facts about Burr.
