Edison Invents the Phonograph

Thomas Edison created many inventions, but his favorite was the phonograph. While working on improvements to the telegraph and the telephone, Edison figured out a way to record sound on tinfoil-coated cylinders. In 1877, 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. In 1878, Edison established the Edison Speaking Phonograph Company to sell the new machine.

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?

Many of the uses Edison suggested for the phonograph have become a reality, but there were others he hadn't imagined. For example, the phonograph allowed soldiers to take music off to war with them. In 1917, when the U.S. became involved in World War I, the Edison Company created a special model of the phonograph for the U.S. Army. This basic machine sold for $60. Many Army units purchased these phonographs because it meant a lot to the soldiers to have music to cheer them and remind them of home. This is an audio clip of Edison himself in which he expresses his pride in the soldiers and reminds Americans of the enormous sacrifice and contribution made by the other allied nations.
