1. The smartest man that ever lived. Period. Did crazy/awesome things like almost destroy an entire city block in New York, designed the first death ray, and melted one of his assistants hands with xrays (by accident). Was also pretty darn crazy, if that wasn't obvious.
2. Also, best vampire ever, as portrayed in Sanctuary
, which happens to be a super awesome show. Edward Cullen, eat your heart out!
The world as we know it would not exist without Nikola Tesla.
