Thomas Alva Edison (1847 - 1903) was the most prolific inventor in the history of the Confederation of North America. Born in the Confederation of Indiana on February 11, 1847, at the age of twenty Edison perfected Aaron Garfield's telegraph. Forming his own company, National Union, Edison won the contract to build the first telegraph line between Burgoyne and Mexico City, completing it in 1876.
By the time of his death in 1903, Edison invented a working light bulb and founded National Electric, which electrified Burgoyne in 1880; invented the telephone and founded North American Communications in 1890; invented the radio in 1896; the phonograph; the motion picture; the locomobile; the vitavision in 1900; and, shortly before his death, the airmobile.
