Edison was a prolific inventor, holding 1,093 U.S. patents in his name, as well as many patents in the United Kingdom, France, and Germany. More significant than the sheer volume of Edison's patents was the widespread and lasting impact of his inventions: the incandescent light bulb (see lot 57), sound and motion picture recording, and many more.
