On This Day in American History
On November 21, 1877, American inventor Thomas Edison announces he’s invented the phonograph, a device which allows the recording and playback of audio. The invention was actually an accident, as he was really trying to figure out a way to record telephone communications using a stylus on a tinfoil cylinder. Edison is also credited with inventing the light bulb and motion picture camera .

                      "1877 Edison’s first great invention(HISTORY)"

The American inventor announces his invention of the phonograph, a way to record and play back sound.

Edison stumbled on one of his great inventions–the phonograph–while working on a way to record telephone communication at his laboratory in Menlo Park, New Jersey. His work led him to experiment with a stylus on a tinfoil cylinder, which, to his surprise, played back the short song he had recorded, “MARY HAD A LITTLE LAMB”. Public demonstrations of the phonograph made the Yankee inventor world famous, and he was dubbed the “Wizard of Menlo Park.”

Edison set aside this invention in 1878 to work on the incandescent light bulb, and other inventors moved forward to improve on the phonograph. In 1887, Edison resumed work on the device, using the wax-cylinder technique developed by Charles Tainter. Although initially used as a dictating machine, the phonograph proved to be a popular tool for entertainment, and in 1906 Edison unveiled a series of musical and theatrical selections to the public through his National Phonograph Company. Continuing to improve on models and cylinders over the years, the Edison Disc Phonograph debuted in 1912 with the aim of competing in the popular record market. Edison’s discs offered superior sound quality but were not compatible with other popular disc players.

During the 1920s, the early record business suffered with the growth of radio, and in 1929 recording production at Edison ceased forever. Edison, who acquired an astounding 1,093 patents in his 84 years, died in 1931.
