Beginning his career

Thomas Edison began his career as an inventor in
Newark, New Jersey, with the automatic repeater and his other improved telegraphic devices, but the invention which first gained him notice was the
phonograph in 1877. This accomplishment was so unexpected by the public at large as to appear almost magical. Edison became known as "The Wizard of Menlo Park," New Jersey. His first phonograph recorded on
tinfoil around a grooved cylinder, but had poor
sound quality and the recordings could only be played a few times. In the 1880s, a redesigned model using wax-coated cardboard cylinders was produced by
Alexander Graham Bell,
Chichester Bell, and
Charles Tainter. This was one reason that Thomas Edison continued work on his own "Perfected Phonograph."
