Édouard-Léon Scott de Martinville ([e.dwaʁ.le.ɔ̃ skɔt də maʁ.tɛ̃.vil]; 25 April 1817 – 26 April 1879) was a French printer, bookseller and inventor.. He invented the earliest known sound recording device, the phonautograph, which was patented in France on 25 March 1857.
First developed by German audio engineers ca. 1943, two-track recording was rapidly adopted for modern music in the 1950s because it enabled signals from two or more microphones to be recorded separately at the same time (while the use of several microphones to record on the same track had been common since the emergence of the electrical era ...

Thomas A. Edison invented the phonograph, the first device for recording and playing back sound, in 1877.After patenting the invention and benefiting from the publicity and acclaim it received, Edison and his laboratory turned their attention to the commercial development of electric lighting, playing no further role in the development of the phonograph for nearly a decade.
The home phonograph disk recorders of the 1930s were expensive machines that few could afford. Cheaper machines, such as the Wilcox-Gay Recordio line, were sold during the late 1930s through the early 1950s. They operated at 78 rpm only and were similar in appearance to (and not much larger than) a portable phonograph of the era.
Shortly after Thomas Edison invented the phonograph, the first device for recording sound, in 1877, he thought that the main use for the new device would be for recording speech in business settings. (Given the low audio frequency of earliest versions of the phonograph, recording music may not have seemed to be a major application.)
