Secret Documents Sent by Radio
Left: the copy picked up and composed by Belinogram. Right: as it appears on other machines
It happened in 1932:
M. BELIN, a French inventor, has perfected a machine known as the “Belinogram”, which makes it possible to send by wireless with absolute safety documents of the most secret nature. The sending machine Belin has developed decomposes the message, document or photograph, while the receiver employed assembles the electrical impulses into the original form. Any other machine, although receiving the same document, finds the signals altogether distorted and of no value whatever.

i used to work at a newspaper in the 60s and we regularly received and sent “belino’s” - i didn’t know about the French inventor.
the quality was good enough for diagrams and even simple well-contrasted photos as for texts we preferred the telex.
then came the fax machine and today e-mail!
