Today in History

Did you know? Today in 1877- Thomas Edison invented the phonograph and made the first sound recording. He created a machine with two needles: one for recording and one for playback. When Edison spoke into the mouthpiece, the sound vibrations of his voice would be indented onto the cylinder by the recording needle. What do you think were the first words that Edison spoke into the phonograph? “Mary had a little lamb” were the first words that Edison recorded on the phonograph and he was amazed when he heard the machine play them back to him. Edison suggested other uses for the phonograph, such as: letter writing and dictation, phonographic books for blind people, a family record (recording family members in their own voices), music boxes and toys, clocks that announce the time, and a connection with the telephone so communications could be recorded. How many of these uses have become a reality today?
