In 1880 Thomas Edison started producing light bulbs. He was not the inventor of the light bulb as others had come before notably Humphry Davy who also created the miners lamp. It was Edison however that refined the research and in doing so produced the first commercially viable bulb. Over the years more companies were established in competition to Edisons and his disagreement over the various electrical systems would ultimately end in Edison losing control of his company.

Edison was a natural and gifted inventor who although being mostly deaf himself managed to invent the phonograph. Thanks Tom!!
