He announced his invention of the first phonograph, a device for recording and replaying sound, on November 21, 1877 (early reports appear in Scientific American and several newspapers in the beginning of November, and an even earlier announcement of Edison working on a "talking-machine" can be found in the Chicago Daily Tribune on May 9 [31 ...

Though no trace of a working paleophone was ever found, Cros is remembered by some historians as an early inventor of a sound recording and reproduction machine. [11] The first practical sound recording and reproduction device was the mechanical phonograph cylinder, invented by Thomas Edison in 1877 and patented in 1878.
The laboratory focused on research for the analysis, recording, and transmission of sound. In 1887, the Volta Laboratory Association transferred the sound recording and phonograph invention patents they had been granted to the American Graphophone Company (later to evolve into Columbia Records).
