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.
