Signed by him as president, and signed a second time by him on the back. The signature as president is lightly cancelled, the other signature is bold and uncancelled. EF. While Thomas Edison was not considered a profound scientific genius, he had a tremendous talent for applying scientific principles to practical applications. In 1876, while experimenting with a needle attached to a telephone receiver, Edison discovred a method that reproduced sounds on a wax cylinder, and the recording industry was born. Edison´s invention relied on mechanical amplification, but by the 1920s his competitors were manufacturing electrically amplified, higher fidelity phonographs. Edison was hard of hearing and could not appreciate the difference in sound quality. He refused to allow his sons to waste time and money to develop an improved electrically amplified phonograph, a decision that would have dire consequences for the Edison Phonograph Works.
