On this day in1877, the publication Scientific American
enthuses about Thomas Edison‘s new invention: the
phonograph, a way to record and play back sound.
Calling it a "wonderful invention," the article describes
the machine’s capability: "…whoever has spoken or
whoever may speak into the mouthpiece of the phonograph,
and whose words are recorded by it, has the assurance that
his speech may be reproduced audibly in his own tones long
after he himself has turned to dust.
