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.

Thomas A. Edison did not simply invent; he created the invention industry. He not only inspired the American Industrial Revolution, he provided the model for modern R&D concepts. Perhaps his greatest success beyond his legacy of innovation and invention is the introduction of team-based research. The
Edison Innovation Foundation is using
Edison's Invention Factory to educate the next generation of inventors.
