Thomas Alva Edison (1847-1931) invented over 1000 inventions. He was born in Milan, Ohio, in the US. In 1879, he demonstrated the first successful electric light bulb. He discovered that electricity would flow from the bulb's glowing filament onto a metal plate inside the bulb. This is known as the 'Edison Effect'.
Nikola Tesla was also a scientist at the same time as Thomas Alva Edison, Tesla originally came from Serbian and became an American scientist. He also was a brilliant and very eccentric genius whose inventions enabled our modern-day power systems and the mass communication systems we all now enjoy.
His opponent and former boss Thomas Edison, was as stated above; the inventor of the light bulb, the phonograph and the moving picture. The two feuding geniuses competed with each other over whose electrical system would be the best system to provide mass electrical energy to the people. Would it be Tesla's alternating-current (AC) system? or Edison's direct-current (DC) system? Do you know who's system is used today to provide us with mass electrical energy?
