Nikola Tesla was a Serbian-American scientist and a brilliant and eccentric genius whose inventions enabled modern-day power and mass communication systems. His nemesis and former boss, Thomas Edison, was the iconic American inventor of the light bulb, the phonograph and the moving picture. The two feuding geniuses waged a "War of Currents" in the 1880s over whose electrical system would power the world — Tesla's alternating-current (AC) system or Edison's rival direct-current (DC) electric power.
