Edison, Thomas Alva (1847–1931)

Born: Milan, Ohio, U.S.A.
Edison is best known as the holder of 1069 patents secured during his lifetime.  Among these were patents for the phonograph and the incandescent filament lamp. Edison was largely self-taught. His early interest in communication devices stemmed from his employment as a telegraph operator. He used
the profits from the sale of his first invention, a “stock ticker,” to set up a lab in Newark, New Jersey. Always a shrewd commercial developer, he followed the invention of the light bulb with work on developing efficient generators to power these bulbs. Edison is considered the archetypal American inventive genius.
