Nikola Tesla
Like da Vinci, there was no test to measure IQ when Nikola Tesla was alive; however, it’s been calculated that his IQ would have been around 200, which is not surprising considering the man invented a lot of things (like remotes) that most of us use on a daily basis (some of which Thomas Edison took credit for). The man predicted cell phones in 1926; he has to be up there with the uber intelligent.
