Edison is credited for contributing to various inventions, including the phonograph, the kinetoscope, the dictaphone, radio, the electric lamp (in particular the incandescent light bulb), the autographic printer, and the tattoo machine. He also greatly improved the telephone by inventing the carbon microphone. Most of these inventions were not completely original but improvements of earlier inventions. Throughout the 20th century, Edison was the world's most prolific inventor. At the beginning of the century, he held 736 U.S. patents. His final count was 1,093 U.S. patents, including 1084 utility patents (patents for inventions) and 9 artistic design patents. (from wikipedia.org)
