EDISON THOMAS: (1847-1931) American Inventor of the phonograph and light bulb among many other items.
A.L.S., Edison, (a somewhat hurried example), one page, 8vo, n.p., n.d. (1921), to [Jaffrey P.] Buchanan. Typically written in bold pencil, Edison writes, in full, 'I want 3 booths in Machines 21 made sound proof like those up stairs & with ventilation. Do it as soon as possible. Driscoll can do it if you tell him what to do. Hurry it'. Some very light, minor age wear, otherwise VG
Jaffray P. Buchanan was employed by Edison as Manager of his Record Disc Division. The present note refers to Edison and Buchanan´s works on the production of the phonograph records.

The American Inventor and Businessman Edison developed many devices that greatly influenced people's lives around the world, including the phonograph, the motion picture camera and, of course, the long lasting and practical light bulb. A prolific inventor, holding more than a thousand US patents to his name, Edison was one of the first inventors to apply the principles of mass production and is often credited with the creation of the first industrial research laboratory. Edison has often been described as America's greatest inventor.
