The invention of the phonograph happened quite a by accident. Thomas Edison moved to Menlo Park, New Jersey, in 1876, where he established an industrial research laboratory. There, Edison was working on a carbon telephone transmitter to improve the existing Bell telephone system.
In that laboratory a year later, Edison invented the phonograph while he was trying to improve a telegraph repeater. He attached a telephone diaphragm to the needle in the telegraph repeater; in this way, he was able to produce a recording that could be played back. After he made some improvements to the machine, he tested it. He recited ‘Marry Had a Little Lamb’ into the machine and played his voice back to a very surprised audience.
