The fultograph was a primitive, clockwork-driven image receiving device like an early fax machine. It took signals from the loudspeaker socket of a radio receiver and used an electrochemical process to darken areas of sensitised paper wrapped round a rotating drum. Invented by one Otto Fulton, the system was used briefly at the end of the 1920s to broadcast images to homes by radio. The machines themselves were expensive (£22.15s.0d in 1928) and required a good quality receiver to operate.[1]

The Fultograph was the subject of an article in the British RadCom amateur radio magazine in October 2007.

A detailed German description of the Fultograph, including several illustrations and a circuit diagram, is available elsewhere on the Internet.[2].

Another German-language description with a good photograph of the Fultograph is available here [3].
