A montage showing portraits of Thomas Edison, with some of his inventions and a recording of him speaking. Some inventions shown include the phonograph, the light bulb, an electric generator, and the quadricycle. Thomas Alva Edison (February 11, 1847 - October 18, 1931) was an American inventor and businessman. He developed many devices that greatly influenced life around the world, including the phonograph, the motion picture camera, and a long-lasting, practical electric light bulb. He was one of the first inventors to apply the principles of mass production and large teamwork to the process of invention, and therefore is often credited with the creation of the first industrial research laboratory.
