"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?
He is also responsible for the Incandescent light bulb, film, movie camera and hundreds more.
