Though he was working on it in 1877 and filed for a patent a few months earlier, it was on this date (February 19th) in 1878 that Thomas Alva Edison received the patent for his newest invention, the phonograph. He was also one of the independent inventors to invent the first microphone during this same time period. All of this happened one year before he created the light bulb.
“The phonograph was developed as a result of Thomas Edison’s work on two other inventions, the telegraph and the telephone. In 1877, Edison was working on a machine that would transcribe telegraphic messages through indentations on paper tape, which could later be sent over the telegraph repeatedly. This development led Edison to speculate that a telephone message could also be recorded in a similar fashion. He experimented with a diaphragm which had an embossing point and was held against rapidly-moving paraffin paper. The speaking vibrations made indentations in the paper. Edison later changed the paper to a metal cylinder with tin foil wrapped around it. The machine had two diaphragm-and-needle units, one for recording, and one for playback. When one would speak into a mouthpiece, the sound vibrations would be indented onto the cylinder by the recording needle in a vertical (or hill and dale) groove pattern. Edison gave a sketch of the machine to his mechanic, John Kruesi, to build, which Kruesi supposedly did within 30 hours. Edison immediately tested the machine by speaking the nursery rhyme into the mouthpiece, ‘Mary had a little lamb.’ To his amazement, the machine played his words back to him.” http://memory.loc.gov/ammem/edhtml/edcyldr.html
What did Thomas Edison foresee the phonograph being used for?
- Letter writing and all kinds of dictation without the aid of a stenographer.
- Phonographic books, which will speak to blind people without effort on their part.
- The teaching of elocution.
- Reproduction of music.
- The “Family Record”–a registry of sayings, reminiscences, etc., by members of a family in their own voices, and of the last words of dying persons.
- Music-boxes and toys.
- Clocks that should announce in articulate speech the time for going home, going to meals, etc.
- The preservation of languages by exact reproduction of the manner of pronouncing.
- Educational purposes; such as preserving the explanantions made by a teacher, so that the pupil can refer to them at any moment, and spelling or other lessons placed upon the phonograph for convenience in committing to memory.
- Connection with the telephone, so as to make that instrument an auxiliary in the transmission of permanent and invaluable records, instead of being the recipient of momentary and fleeting communication.
For those of us involved in this paranormal “field”, I wonder where we’d be if it weren’t for Edison or his inventions? And I wonder if Edison had any idea that his inventions would be so important in the future of Electronic Voice Phenomena and spirit communication in general? Edison had an interest in spirit communication and it is widely believed that before his death he was working on a type of telephone to the dead and other tools that would have been a great help to this field. And who knows? Maybe we’re using new inventions from Edison today? Many mediums and researchers claim to have made contact with him over the years. Maybe he has passed all of this expertise onto mortal inventors, scientists, and inventors?
