Thomas Edison and Charles Ginsburg: Two great Inventors.

The first great invention developed by Thomas Edison in Menlo Park was the tin foil phonograph. While working to improve the efficiency of a telegraph transmitter, he noted that the tape of the machine gave off a noise resembling spoken words when played at a high speed. This caused him to wonder if he could record a telephone message. He began experimenting with the diaphragm of a telephone receiver by attaching a needle to it. He reasoned that the needle could prick paper tape to record a message. His experiments led him to try a stylus on a tinfoil cylinder, which, to his great surprise, played back the short message he recorded, “Mary had a little lamb.”

The word phonograph was the trade name for Edison’s device, which played cylinders rather than discs. The machine had two needles: one for recording and one for playback. When you spoke into the mouthpiece, the sound vibrations of your voice would be indented onto the cylinder by the recording needle. This cylinder phonograph was the first machine that could record and reproduce sound created a sensation and brought Edison international fame.

August 12, 1877, is the date popularly given for Edison’s completion of the model for the first phonograph. It is more likely, however, that work on the model was not finished until November or December of that year, since he did not file for the patent until December 24, 1877. He toured the country with the tin foil phonograph, and was invited to the White House to demonstrate it to President Rutherford B. Hayes in April 1878.

In 1878, Thomas Edison established the Edison Speaking Phonograph Company to sell the new machine. He 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.

Charles Ginsburg led the research team at Ampex Corporation in developing the first practical videotape recorder (VTR). The system used a rapidly rotating recording head to apply high-frequency signals onto a reel of magnetic tape.

The VTR revolutionized television broadcasting. Ginsburg led the Ampex research team that developed a new machine that could run the tape at a much slower rate because the recording heads rotated at high speed, allowing the necessary high-frequency response. Recorded programs that could be edited replaced most live broadcasts. In 1956, CBS became the first network to employ VTR technology.
