Nikola Tesla - a genius ? At least a person who's concepts are still far from widely understood.
Preston Tucker - although no scientist, his works are still unmatched. Only last year I read about the first automobile featuring his unique "middle lamp" for enlightenig the road as the driver uses the steering wheel.
Jules Verne - although no scientist, his concepts sketched in his works were far aheade of his time.
(Sorry, I
wanted Jules Verne to be in.)
