The day after Edison got the idea of ​​recording voice messages received by telegraph, he got the idea of ​​implementation. That evening, July 18, 1877, after lunch in the laboratory, Edison turned to his assistant, Charles Bachelor, and remarked: “Bach, if we put a needle here, we can write something down, and then stretch it under a needle and get a record.”
After this proposal seemed so obvious, they did not even begin to admire him, but immediately turned to the experiments. An hour later, the design was on the table. Edison sat down, ducked to the sound receiver and said the phrase, which in the laboratory tested telephone diaphragms: "Our Mary had a ram."
Bachelor inserted a strip on which the phrase was written, again, and she issued "at ... necks ... ri ... ain ... wounds." “It was not very clear,” recalled Bachelor, “but the essence was clearly bugged.” The men issued a victory cry, shook hands and continued their work. By the next breakfast, they managed to get a clean reproduction from waxed paper (first audio carrier) after the first recording that day.
The discovery was mentioned in the magazine surprisingly casual.
This was an important moment in the history of inventions, but in subsequent years, Edison never told the story the way it actually happened that summer, but constantly shifted events from July 1877 to December. You can guess why: in July, he and his assistant did not attach due importance to their discovery. At that time, they worked hard to create working phones to show them in Western Union. There was no time to stop and think about the random invention of the first working model of the phonograph.
The invention was noted in notebooks under the “talking telegraph” rubric, as it was intended to be used at telegraph stations to record messages. One of the employees made a list of possible names for the car, which included: tel-autograph, tel-avtofon, chronophone - time-talker - talking clock, diddascofon - talking teacher - portable teacher, glottophone - language device, climate phone - weather announcer, klangofon - bird singing replicator, hulammophone - husker ( who, who, who, who let the dogs out?) comment
In October 1877, Edison wrote to his father that he "currently needs money," but if his "talking telegraph" is waiting for success, he will be given an advance from royalties. The commercial potential of this unnamed device was not visible to him.
A phonograph description in Scientific American in November caused frenzy in Europe and America. In The New York Sun were struck by the metaphysical consequences of the invention, which could lose the "echo of dead voices." The New York Times predicted (which strangely coincided in essence with their review article on the Internet in the mid-1990s) that great business can be done on “bottled sermons”, and wealthy experts will show off the assembled cellars with public speaking sets.
Such was the authority of Scientific American that all this hysteria happened not because of a working phonograph model put on display, but only because of the description made by Edison's assistant.
In late November, Edison and his team guessed the commercial potential of the phonograph as a device for entertainment. A list of possible uses was made: talking toys, toy trains, music boxes, talking clocks. There was even a hint of future music collections - a phonograph, as a car for the whole family, equipped with thousands of music recordings, could provide "unlimited fun".
But the real model was still not built. December 4, 1877 in the diary of Bachelor read: "our employee John Cruise built a phonograph today." Unremarkable entry; above it is “working on the talking telegraph” ...
On December 7, Edison entered Scientific American's New York office, put a small typewriter on the table, and in the presence of a dozen people gathered around, turned the handle of the plant. “How are you?” The car asked, slightly hoarse. "How do you phonograph?". The phonograph told the audience that he himself was feeling fine and wished everyone good night.
Working in the field of telegraph equipment, Edison was perfectly prepared for the sudden inspiration for the invention of the phonograph. But that world, focused on huge industrial customers, had nothing to do with the market.
