Developed in the 1870s, the Hectograph (also spelled Hektograph) was an early document copying process which used a tray of gelatine to transfer ink from a master sheet onto copy pages. Extremely simple and easy to construct under primitive conditions, they were extensively used by underground political groups and prisoners of war to secretly print documents.
