    Edison was considered one of the most prolific inventors of his time, holding a record 1,093 patents in his name. Most of these inventions were not completely original but improvements of earlier patents, and were actually made by his numerous employees - Edison was frequently criticized for not sharing the credits. Nevertheless, Edison received patents worldwide, including the United States, United Kingdom, France, and Germany. Edison started the Motion Picture Patents Company, which was a conglomerate of nine major film studios (commonly known as the Edison Trust).

    List of contributions:





    electric bulb

    autographic printer

    tattoo gun

    By the end of his life Edison had registered 1093 patents and had made millions from his inventions and the businesses he built on them.

    Edison was a borrower - he copied many other people's ideas - mostly Europeans - then patented their ideas in the USA.

    Other "inventions" credited to him, such as the motion picture camera or projector, had little to do with the product that was actually used.

    Edison got his money from "borrowing" other people's inventions and patenting them himself.

    When he "invented" the light bulb, Mosely Street in Newcastle, England, was already lit by electric light bulbs. The inventor, Joseph Swan, sued Edison and won - however, he agreed to go into partnership with Edison & marketed the light bulbs through the Swan-Edison company.

    RADIO? How can anyone say that Edison invented the radio?

    Marconi developed the technology to into a usable format.
