How Edison Invented the Light Bulb
Thomas Edison didn’t “invent” electricity. But he did find a way to make electric lighting available to the masses.
In 1878, Edison accompanied a scientific expedition to Wyoming to view a total eclipse of the Sun. He also wanted to use his newly invented tasimeter to measure the heat from the Sun’s corona during the eclipse. Edison became inspired by talks with fellow scientists. He said that he would invent a safe, inexpensive electric light.
