Nikola Tesla was a famous 20th century Serbian-American scientist who is most famous for designing the alternating current (AC) electricity supply system.
The world-famed engineer could speak in eight languages, had an eidetic memory and held 300 patents by the time he died. His name was borrowed for the red-hot car and energy storage company created by entrepreneur Elon Musk and he has been cited as an inspiration by Google co-founder Larry Page.
It seems Tesla predicted the creation of the mobile phone in a 1926 interview. Wow.
"When wireless is perfectly applied the whole earth will be converted into a huge brain, which in fact it is, all things being particles of a real and rhythmic whole. We shall be able to communicate with one another instantly, irrespective of distance. Not only this, but through television and telephony we shall see and hear one another as perfectly as though we were face to face, despite intervening distances of thousands of miles; and the instruments through which we shall be able to do his will be amazingly simple compared with our present telephone. A man will be able to carry one in his vest pocket."
