EDISON - AUTOGRAPH NOTE SIGNED - HFSID 67845 THOMAS A. EDISON The inventor write to his lab supervisor regarding experiments on his favorite invention, the phonograph. ANS: "E" in pencil, 1p, 5x8, ruled sheet. No place, no date. To "Moore". In full, as written: "You dont (sic) keep in touch with me = What has become of the Experiments to get blanks with hard Centers, Read this, still have soft Centers. It would appear easy to get the hard center". Handwritten postscript: "They have stopped using Rea[illegible] machine on Amberol for a week waiting for you to decide something say works OK but Knifes (sic) dull". THOMAS ALVA Edison, who writes to laboratory supervisor, S.A. Moore, had introduced Amberol, an unbreakable cylinder, in November 1908 and then created the Blue Amberol, which had a longer playing time. Despite eventually turning from cylinders to discs, Edison's company continued to manufacture the Amberol cylinders until 1929. Originally, in 1877, Edison's phonograph had a receiver, a delicate metal needle that operated on a phonograph blank of white wax. The surface of the wax blank (which looked like an ivory box) could record from 1,000 to 1,200 words or several musical compositions. The wax blank then could be automatically pared from 15-20 times for new records. Between 1912 and 1926, Edison continually refined his discs starting with the Edison Disc Records in 1912 and launching his marketing sensation, The Re-Creation Disk, in 1919. The up and down groove enabled the record to play 50% longer than the "talking machine" record of the same size. A 10-inch Edison Disc record played longer than a 12-inch lateral groove. His Re-Creation Disk was molded in greater thickness and from a harder substance than an ordinary record, making it more durable. The phonograph was Edison's favorite invention. Lightly creased with folds, light vertical fold at the "E". Lightly soiled. Chipped at blank right edge, irregular upper edge from removal from pad. Overall, fine and interesting.
