Thomas Alva Edison with his cylinder phonograph in 1878.

Thomas Edison is known for his many inventions, but his favorite was the
phonograph which was created while working on improvements to the
telegraph and the telephone. He figured out a way to record sound on
tinfoil-coated cylinders with two needles, one for recording and one
for playback. His first words he recorded on the new machine were,
”Mary had a little lamb”.
