In 1879, Thomas Edison developed an electric light bulb which could be used at home, and he brought the electric light to the public masses. Currently we can’t live even a day without electricity to light our homes. So Edison is one of the great figures in human history in the fields of science and culture. He also invented the phonograph and moving pictures. Thanks
