Thomas Edison in about 1922 Thomas Alva Edison (1847–1931) was an American inventor. Some of his inventions were improvements on those that already existed, but he turned them into versions that could be widely used. His achievements included the phonograph, the earliest sound recording device, a vastly improved telephone and an electric light bulb that worked better than anything that had gone before. Edison also founded 14 commercial companies, including what is now General Electric, one of the largest public limited companies in the world.
Thomas Alva Edison was born in Ohio in 1847, and grew up in Michigan. He did badly at school, so his mother, a qualified teacher, taught him at home.
Edison got his first job as a telegrapher, aged 15, after he had rescued a three-year-old child on a railway track from being crushed by a freight wagon. The child’s father was the railway's stationmaster.
