19. Nikola Tesla
Nikola Tesla was a futurist and inventor. Born in Serbia, he emigrated from Serbia to the United States to work for Thomas Edison. He soon separated from his role model and found his own backing to pursue his discoveries and inventions in electrical current and providing electricity to the masses. Telsa even came up with a way to offer limitless power from the ground completely free, but his vision never became a reality because it would not be financially profitable.
