At the turn of the last century, Thomas Alva Edison invented the electric light bulb, making it possible for the first time to light up the world at night.
“It’s a miracle!” screamed the guests at the party, “You are a genius, Mr. Edison!”
It had taken him years to find the right filament that would last more than just a few minutes, called tungsten.
At the 1904 World’s Fair, in Saint Louis, Edison’s invention, the incandescent light bulb, lit up the fair at night. People were so amazed it frightened some because there was so much bright light.
