Ediphone (1888 – early 1950s)

The Ediphone was one of two competing wax cylinder phonograph systems for voice dictation, the other being the Dictaphone system. The use of cylinders for voice recording pre-dated their use for music, although it wasn’t until 1888 that Edison switched from tinfoil to wax cylinders in response to the rival Graphophone system introduced in 1887 (that later became the Dictaphone system).

The main difference between the two rival systems was the recording method, with Edison using ‘hill and dale’ recording, while the Graphophone used lateral (side to side) recording. The cylinders could have a layer of wax shaved off, to enable re-use.

By around 1910, the Edison system had adopted the name Ediphone, and technical refinements were introduced over time such as electric motors, foot control pedals, and eventually electrical recording in 1939.

By the mid-1940s, new dictation technologies were rapidly being introduced such as Dictaphone’s Dictabelt, Edison’s own Voicewriter, the Gray Audograph and the SoundScriber, and both Edison and Dictaphone stopped supplying wax cylinders in the early 1950s.
