The phonograph was invented quite by accident. In 1876 Thomas Edison moved to Menlo Park, New Jersey, where he established an industrial research laboratory. There Edison worked on a carbon telephone transmitter to improve the existing Bell system.
In that laboratory a year later Edison invented the phonograph while trying to improve a telegraph repeater.
He attached a telephone diaphragm to the needle in the telegraph repeater to produce a recording that could be played back. After some improvements to the machine he recited “Marry Had a Little Lamb” and played the recognizable reproduction of his voice back to the astonished audience.
