During his life, over 1100 patents were issued to him or his associates; he was known as the wizard of Menlo Park, the town in New Jersey where he set up his first invention factory. Yet he was not really a scientist, having no theory or mathematics, and most of his success came from perfecting the ideas of others or already existing inventions by trial and error.He learned telegraphy on the railway, and his services as a telegrapher were in demand during the Civil War, when he traveled all over the country, incidentally studying electricity. In 1868 came his first invention: a machine to record votes in Congress. But Congress turned it down, because they were not interested in speeding up matters.

At this moment Edison had invented the concept of commercial inventing, which has dominated twentieth-century technology. The company will soon supply current to all of Manhattan and it will develop into the Consolidated Edison Co. He also made improvements to the typewriter. Morgan to light the offices and inaugurate commercial transmission of electric power from the Morgan-financed Edison Illuminating Co. Also his invention of the vacuum tube helped not only the radio invention but it was one of the key instruments in the first computer, another invention which I cannot possibly imagine life without. In 1887, Edison moved to a larger laboratory in West Orange, New Jersey. The Edison Electric Light Company, however, grew by mergers to become the General Electric Company. The first recording ever made was of Edison's own voice reciting Mary Had a Little Lamb. , prototype of all central-station U.
