Light Bulb

Thomas Edison's greatest challenge was to make an electric light.He didn't "invent" the lightbulb, but he improved upon a 50-year-old idea. After one and a half years of work, success was achieved when an lamp with a filament burned for thirteen and a half hours. The success of his electric light brought Thomas Edison to new heights of fame and wealth, as electricity spread around the world. His electric companies continued to grow until in 1889 they were brought together to form Edison General Electric.
