Phonographs, Graphophones, Gramophones, and so on. . .

Thomas Edison had been working on telephone equipment at the time he conceived the phonograph. Alexander Graham Bell announced his telephone in 1876, and many inventors set out to duplicate and improve it. Edison, drawing on his vast experience in telegraph equipment, in July 1877 conceived of the idea of using a sensitive electromagnetic device to inscribe telephone messages on a strip of wax-coated paper. Probably unknown to Edison was a similar concept described in April 1877 by Frenchman Charles Cros. The latter would later claim precedence with some justification.

A sketch of one of Edison's earliest phonographs. A sheet of thick tinfoil, wrapped around cylinder "C" is indented by a stylus attached to diaphragm "A." This hand-cranked machine was of the type used to demonstrate the principle. Production models had provisions for keeping the speed constant and other improvements.

After some experimentation, he turned instead to a device that could record straight from the air instead of relying on a telephone connection. This line of inquiry resulted in the construction of the first functional phonograph in early December, 1877. He demonstrated it almost immediately in the New York office of Scientific American magazine, and in subsequent months the publicity the invention generated resulted in a new nickname for Edison: "The Wizard of Menlo Park" (referring to his Menlo Park, New Jersey laboratories).

Edison did little to commercialize the phonograph himself, and a limited number of licensees made unsuccessful attempts to sell the new device, including a German firm that introduced a talking doll.

Within a decade, however, Edison had a new competitor in the form of the Graphophone. Essentially an improved phonograph, the new recorder stimulated Edison to return to his invention, and the result in 1886 was the improved phonograph. Phonograph and graphophone licensees attempted to lease or sell the devices to stenographers to replace hand-writing. They made little money until someone had the bright idea to make a coin-operated phonograph for public amusement. By supplying ready-made cylinders, they transformed the device into an entertainment technology. Following much legal wrangling over patents in the 1890s, Columbia Phonograph emerged as a major competitor to the Edison company, and survives today as part of CBS Records.
