Thomas Edison is important because he invented a lot of different things such as the electric light, the stock ticker, the phonograph, the motion picture camera, and 1,200 other things. With the motion picture camera, he changed people's lives. If someone passes away, they will still remember them with the motion pictuer camrea.
The electric light was a very important invention. Before the electric light, people had to use candles. If wind blows on a candle, it may go out. This is not a problem with the electric light.
