The letter is two pages and measures 8.5" x 10.5" (20.96 x 26.67 cm). Edison (1847-1931) was born in Milan, Ohio. He gained fame as an inventor, registering a total of 1,093 patents for such innovations as the incandescent light bulb, the phonograph, and the moving picture camera. As a boy, Edison was boxed in the ears by an angry train conductor after he destroyed a box car when his science experiments exploded. Edison pointed to the incident as the cause of his loss of hearing, which worsened throughout his life. View on Ohio Memory.
