Fultograph – Invented by Otto Fulton

The fultograph was an early precursor to the fax machine.

It worked by transmitting signals over a radio receiver, and used an electrochemical process to darken areas of a sensitized paper wrapped over a rotating drum.

Invented by Otto Fulton, the system was used in the late 1920s to broadcast images over the radio waves.

It has been noted that the machines were expensive and needed a qualified receiver to operate them.
