Édouard-Léon Scott de Martinville (25 April 1817 – 26 April 1879) was a French printer and bookseller who lived in Paris.
As a printer by trade, he was able to read accounts of the latest scientific discoveries and became an inventor. Scott de Martinville was interested in recording the sound of human speech in a way similar to that achieved by the then new technology of photography for light and image. He hoped for a form of stenography that could record the whole of a conversation without any omissions. His earliest interest was in an improved form of stenography and he was the author of several papers on shorthand and a history of the subject (1849).
From 1853 he became fascinated in a mechanical means of transcribing vocal sounds. While proofreading some engravings for a physics textbook, he came across drawings of auditory anatomy. He sought to mimic the working in a mechanical device, substituting an elastic membrane for the tympanum, a series of levers for the ossicle, which moved a stylus he proposed would press on a paper, wood, or glass surface covered in lampblack. On 26 January 1857, he delivered his design in a sealed envelope to the French Academy. On 25 March 1857, he received French patent #17,897/31,470 for the phonautograph.:13, footnote 85
To collect sound, the phonautograph used a horn attached to a diaphragm which vibrated a stiff bristle which inscribed an image on a lamp black coated, hand-cranked cylinder. Scott built several devices with the help of acoustic instrument maker Rudolph Koenig. Unlike Edison's later invention of 1877, the phonograph, the phonautograph created only visual images of the sound and did not have the ability to play back its recordings. Scott de Martinville's device was used only for scientific investigations of sound waves.
Scott de Martinville managed to sell several phonautographs to scientific laboratories for use in the investigation of sound. It proved useful in the study of vowel sounds and was used by Franciscus Donders, Heinrich Schneebeli and Rene Marage. It also initiated further research into tools able to image sound such as Koenig's manometric flame. He was not, however, able to profit from his invention and spent the remainder of his life as a bookseller dealing in prints and photographs, at 9 Rue Vivienne in Paris.
Scott de Martinville also became interested in the relationship between linguistics, people's names and their character and published a paper on the subject (1857).

In 2008, The New York Times reported the playback of a phonautogram recorded on 9 April 1860. The recording was converted from "squiggles on paper" to a playable digital audio file by scientists at the Lawrence Berkeley National Laboratory in Berkeley, California. The phonautogram was one of several deposited by Léon Scott in two archives in Paris and only recently brought to light.
The recording, part of the French folk song Au clair de la lune, was initially played at a speed that produced what seemed to be a 10-second recording of the voice of a woman or child singing at an ordinary musical tempo. The researchers leading the project later found that a misunderstanding about an included reference frequency had resulted in a doubling of the correct playback speed, and that it was actually a 20-second recording of a man, probably Scott himself, singing the song very slowly. It is now the earliest known recording of singing in existence, predating, by 28 years, several 1888 Edison wax cylinder phonograph recordings of a massed chorus performing Handel's oratorio Israel in Egypt.
A phonautogram by Scott containing the opening lines of Torquato Tasso's pastoral drama Aminta, in Italian, has also been found. Recorded around 1860, probably after the recording of Au clair de la lune, this phonautogram is now the earliest known recording of intelligible human speech. Recordings of Scott's voice made in 1857 have also survived, but they are only unintelligible snippets.
It has been claimed that in 1863 Scott's phonautograph was used to make a recording of Abraham Lincoln's voice at the White House. A phonautogram of Lincoln's voice was supposedly among the artifacts kept by Thomas Edison. According to FirstSounds.org, these stories are variations of a myth that seems to have first appeared in print in a 1969 book about antique collecting, in which it is explicitly categorized as a legend and dismissed as based on "garbled accounts". There is no solid evidence that such a recording ever existed. The most nearly similar artifact known to have been kept by Edison was a recording of the voice of President Rutherford B. Hayes, captured as a groove indented into a sheet of tinfoil when Edison demonstrated his newly-invented phonograph to Hayes in 1878. Scott did not visit the US in the 1860s and therefore could not have recorded Lincoln himself, as one version of the legend claims he did.
Scott's phonautograms were selected by the Library of Congress as a 2010 addition to the National Recording Registry, which selects recordings annually that are "culturally, historically, or aesthetically significant".
Edouard-Leon Scott de Martinville was born in France in 1817.
An "ethereal" 10 second clip of a woman singing a French folk song has been played for the first time in 150 years. The recording of "Au Clair de la Lune", recorded in 1860, is thought to be the oldest known recorded human voice.
He invented a device called the phonautograph, and, on 9 April 1860, recorded someone singing the words, 'Au clair de la lune, Pierrot repondit [sic].' But he never had any intention of playing it back. He just wanted to study the pattern the sound waves made on a sheet of paper blackened by the smoke of an oil lamp.
The audio excavation could give a new primacy to the phonautograph, once considered a curio, and its inventor, Édouard-Léon Scott de Martinville, a Parisian typesetter and tinkerer who went to his grave convinced that credit for his breakthroughs had been improperly bestowed on Edison.
In 1863, nearly 15 years before Thomas Alva Edison created the first phonograph, an inventor named Leon Scott is said to have visited the White House. If historical anecdotes are accurate, he made a tracing of President Lincoln's voice with his newly invented 'phonautograph,' a machine that scratched sound patterns onto a soot-blackened sheet of paper wrapped around a drum.
