Stollwerck chocolate disc phonograph, 1903.
© Science Museum / Science & Society Picture Library
This charming toy was produced by the German confectionery firm Stollwerck, which for a short time owned the patent rights to the phonograph. It has been established that it played chocolate discs 11.5 cm in diameter, but it is not clear whether it was the chocolate itself that was played or the outer foil wrapper. A more durable cardboard record was also available. The discs, turned by a clockwork motor, were cut on the 'hill-and-dale' principle which originated with Edison's phonograph of 1877.
