With a lifetime dedicated to invention, Thomas A. Edison (1847 – 1931) earned 1,093 U.S. patents, more than any other single inventor. His impressive achievements include the invention of electric lighting, the phonograph, and motion pictures. Edison was not only a successful inventor but also an excellent businessman who created companies to manufacture his inventions. As befits a man of his talents, there are many websites devoted to Edison and his inventions. These are my favorites.
