Early Sound Recording Collection and Sound Recovery Project

Background on the Early History of Recorded Sound

In 1877, Thomas Edison invented the phonograph, the first machine that could record sound and play it back. On the first audio recording Edison recited, “Mary had a little lamb. Its fleece was white as snow. And everywhere that Mary went, the lamb was sure to go.”  Edison recordings were made on tin foil and could sustain replaying only a few times.  Nevertheless, Edison’s little machine was an immediate sensation, widely demonstrated and covered by the press.

After the initial excitement around his invention, Edison turned from work on his “talking machine” to improve the electric light bulb.  He would not work on the phonograph again until the late 1880s, when wax cylinders replaced tin foil as his recording medium.

Sound recording instruments before Edison’s did exist, but they were not intended to replay what had been recorded.  Notable among these was Frenchman Leon Scott’s phonautograph.

Inspired by Edison’s work with sound recording, other inventors sought to improve the phonograph. Among the most noted were Alexander Graham Bell and Emile Berliner.  Bell and his associates experimented with disc and cylinder recordings and their graphophone, which employed wax cylinder records, became a popular dictating machine.  Berliner had commercial success with disc records and the machine to play them—the gramophone.  The material evidence of this invention story can be seen--and now heard--through artifacts at the Smithsonian’s National Museum of American History.

The Smithsonian Collection of Early Sound Recordings

Thomas Edison, Alexander Graham Bell, and Emile Berliner vied to invent records and machines to play them on. Each inventor offered objects and supporting documents to the Smithsonian Institution, where they became part of the permanent collections. Today, the National Museum of American History has about 400 of the earliest audio recordings ever made. These recordings were made using a variety of methods and materials such as rubber, beeswax, glass, tin foil and brass, as the inventors tried to find a material that would hold sound.   They date from the first decades of sound recording and reproduction, from 1878 to 1898.

Beyond vague notes written on old catalog cards, the content of most of the Smithsonian recordings has remained a mystery, until now.  A newly invented sound recovery process is beginning to let us hear these recordings, once considered unplayable.  The recordings provide insights into the invention process of their designers and shed new light on speech and hearing at the end of the 19th century.  These sounds promise a wealth of new material for scholarly analysis.

The Sound Recovery Process

The Museum’s recording collection has begun to benefit from a noninvasive sound recovery process developed at Lawrence Berkeley National Laboratory. A test of six recordings has undergone the process on imaging equipment installed by Berkeley Labs at the Library of Congress.   These imaging methods protect the records from damage and can circumvent many aspects of pre-existing damage.  Details on the process can be found at http://irene.lbl.gov/.

This sound recovery activity has been a collaborative effort of Lawrence Berkeley National Laboratory, the Library of Congress, and the Smithsonian Institution.  The Institute of Museum and Library Services and the Jackson Fund at the National Museum of American History have provided funding.  The National Museum of American History has received additional support from the Grammy Foundation and the Museum’s Lemelson Center for the Study of Invention and Innovation.

Pilot Project Preliminary Findings:  Smithsonian Recordings from Alexander Graham Bell’s Volta Laboratory

The six recordings, tested for sound recovery to date, are examples of experiments conducted by the Volta Laboratory Associates—Alexander Graham Bell, his cousin Chichester Bell, and Charles Sumner Tainter—roughly between 1880 and 1885. 

Bell and Tainter began research on sound in Washington, D.C., in 1879.  A year later, with the Volta Prize—funds awarded by the government of France to Bell for his work on the telephone—they set up a new laboratory, added the chemistry skills of Chichester Bell, and continued work on sound research of all sorts until the association dissolved early in 1886.  The Smithsonian collections contain experimental apparatus, recordings, and documents from Bell’s Volta Laboratory.  The Library of Congress holds the home and laboratory notes for both the Bells from this period.

On three occasions—28 February 1880, 6 April 1880, and 30 October 1881—the Volta Associates deposited sealed tin boxes with the Smithsonian Institution.  The first two contained objects and documents pertaining to the photophone, a device invented to carry sound on light waves.  The third contained apparatus and notes pertaining to a new kind of sound recording device—the graphophone.   Already undergoing numerous challenges to his telephone patent, Bell sought to avoid future disputes about his photophone and graphophone work.  These sealed deposits would, if necessary, serve as evidence of priority of invention.  No patent dispute arose, and the boxes remained confidential and unopened for nearly fifty years.  Smithsonian officials unsealed them in the presence of Bell’s daughters and a grandson in 1937.

1. Electrotyped copper negative disc of a sound recording, deposited at SI in October 1881 in sealed tin box.  Content: Tone; male voice saying: “One, two, three, four, five, six”; two more tones.  Listen

2. Glass disc recording, produced photographically on November 17, 1884.  Inscription: “Exp. III Nov. 17 1884/Style vibrations to word/ Barometer/H. G. Rogers.”  Content: male voice saying: “ba-ro-me-ter”; each syllable is distinct and the word is repeated.  Listen

3. Glass disc recording, produced photographically on March 11, 1885.  Content: male voice saying names, recording date, “Mary had a little lamb” repeated twice.  Listen

4. Disc recording in green wax on brass holder, probably 1885.  Content: male voice reciting opening lines of “To be, or not to be” soliloquy from Hamlet.  Listen

5. Recording in wax on binder’s board, probably 1885.  Content: in two segments with a gap in between; first segment is a male voice reading a story.  At 51.8 seconds the voice suddenly changes to a high pitched “child imitation.”  In the second segment a man is reading from a description of a New Hampshire factory.  Listen Part 1 Part 2
