Thomas Edison was born in 1847 In Milan, Ohio. He was nicknamed 'Al' at an early age. At age 11, Edison moved to Michigan where he spent the remainder of his childhood. Thomas Edition struggled at school but learned to love reading and conducting experiments from his mother who taught him at home. At age 15, Edison became a 'tramp together', sending and rece1vrng messages via Morse code, an electronically-conveyed alphabet using different clicks for each letter. In 1870, Edison moved to New York City and improved the stock ticker. He soon formed his own company that manufactured the new stock tickers. He also began working on the telegraph and invented a version that could send our messages at once. Edison then moved with his family to New Jersey where he started his famous laboratory. In 1877, Edison, with help from 'muckers', individuals from around the world looking to make fortune in America, invented the phonograph. The phonograph was a machine that recorded and played back sounds. In 1878, Edison invented the light bulb as well as the power grid system, which could generate electricity and deliver it to homes through a network of wires. He subsequently started the Edison Electric Light Company in October of 1878. Edison continued to invent or improve products and make significant contributions to X-ray technology, storage batteries and motion pictures (movies). Edison was a prolific inventor, holding 1,093 US patents in his name, as well as many patents in the United Kingdom, France, and Germany.
