His invention inscribed an image on a cylinder coated in  lampblack, which he then pressed onto paper. Unfortunately he had no  means to play back the sounds that he had recorded. Twenty years later,  another Frenchman, the scientist Charles Cros, had the idea of recording  sounds by using an oscillating diaphragm to engrave a cylinder that  could then be used to produce a similar oscillation. He submitted his  idea to the Academy of Science in Paris in a letter that he sealed in an  envelope in April 1877, but he did not make any prototypes of his  Paleophone, as he called it.<\/p>\n<p>The following month the American  inventor began work on a way to transmit an automated human voice over  the telephone. Apparently, quite independently of Cros, he developed a  system where the oscillation of a diaphragm was recorded on a cylinder  of tinfoil by means of an attached stylus. In November 1877 Edison  announced and then demonstrated his phonograph. He submitted the patent  application on Christmas Eve that year and on 19th February 1878 Edison  received U.S. Patent 0,200,521 (his 117th US patent) for his &#8216;Phonograph  or Speaking Machine.&#8217;<\/p><\/div>\n","protected":false},"excerpt":{"rendered":"<p>In March 1857, the French printer and bookseller, \u00c9douard-L\u00e9on Scott de Martinville, patented the first device for recording sound, the phonautograph.
