Thomas Alva Edison (1February 84711931year1October 18) was born in Milan, Ohio, and died in West Orange, New Jersey, USA. Inventors and entrepreneurs.

Edison was the first person in human history to use a large number of production principles and electrical engineering research laboratories to patent inventions, which had a great and far-reaching impact on the world. His invention of the phonograph, movie camera and electric light had a great influence on the world. He had more than 2,000 inventions and 1000 patents in his life.
