Why is the history of electric light fascinating?

For thousands of years, people all over the world have been fascinating by lightning. In 1752, a genius named Benjamin Franklin conducted an experiment to prove that lightning was caused by electricity. Throughout the next hundred years, many inventors and scientists tried to find a way to use electrical power to make light.

In 1800's Humphrey Davy, an English scientist, experimented with electricity, and invented an electric battery. When he connected wires to his battery and a piece of carbon, the carbon glowed, producing light. This is called an electric arc.

Later, the English physicists Sir Joseph Wilson Swan demonstrated his new electric lamps in England. These lamps used a carbon filament inside a glass bulb to produce incandescent light. However, it was the inventor Thomas Alva Edison's lamp that became the first commercially successful incandescent lamp. In 1910 William David Coolidge lasted even longer that the older filaments. This incandescent bulb revolution ed the world.
