Thomas Alva Edison was an American inventor in the late 19th century who developed many pioneering technologies including the phonograph and incandescent light bulb. He established the first industrial research laboratory in Menlo Park, New Jersey where he worked with large teams to develop and mass produce his inventions. Edison is credited with developing the infrastructure for electric power and making significant improvements to the idea of incandescent lighting that led to its widespread adoption. Some of his most influential inventions were the phonograph, the first device that could both record and reproduce sound, and the long-lasting, practical light bulb.
