Edison, Thomas Alva
| (1847-1931), U.S. engineer who had 1,093 patents (more than any other single inventor), known for his systematic approach to design and for providing a classical example of how an inventor works within the internal logic of technology. His most well-known inventions are the phonograph (1878), the carbon-button transmitter for the telephone speaker and microphone (1877), the incandescent lamp (1879), a revolutionary generator of unprecedented efficiency (1879), the first commercial electric light and power system (1882), and the key elements of the motion-picture apparatus (1891). He also established the prototypical industrial research laboratory -- first in Menlo Park then West Orange, New Jersey. He was an honorary member of ASME. He was born Feb. 11, 1847, Milan, Ohio, and died Oct. 18, 1931, West Orange, New Jersey. |
