Towards the end of the 1800s, there were three primary American groups competing to invent technology to record and play back audio. Alexander Graham Bell worked with with Charles Sumner Tainter and Chichester Bell in at their Volta Laboratory in Georgetown, Washington, D.C., while Thomas A. Edison worked from his Menlo Park facilities, and Emile Berliner worked in his independent laboratory in his home. To secure the rights to their inventions, the three groups sent samples of their work to the Smithsonian. These recordings became part of the permanent collections, now consisting of 400 of the earliest audio recordings ever made. But knowledge of their contents was limited to old, short descriptions, as the rubber, beeswax, glass, tin foil and brass recording media are fragile, and playback devices might damage the recordings, if such working devices are even available. That is, until a collaborative project with the Library of Congress and Lawrence Berkeley National Laboratory came together to make 2D and 3D optical scanners, capable of visually recording the patterns marked on discs and cylinders, respectively.

Last year we discussed a recently discovered 10-second audio recording from 1860 that was thought to be the oldest known recorded human voice, a girl or woman singing the 18th century French folk song “Au Clair de la Lune”. Turns out, it was being played too fast - slow it down and it's the voice of the inventor himself. As well, a number of other recordings have been found, pushing back the oldest recording to 1857. Hear it all on NPR (5-min). [more inside]

Some technological histories - including Edison's Electric Pen, a History of the Atlantic Cable & Submarine Telegraphy, and Cox's 1907 Gold Changer.
