HELL was a manufacturer of
teleprinter, fax and
cipher machines, based
in Kiel (Germany).
The company was founded in 1929 by
Rudolf Hell, one of Germany's most
important and productive inventors of the previous century.
Nevertheless, the HELL company is generally not well-known.
In the period following WWII, HELL built a number of mechanical
cipher machines for the German Army (Bundeswehr),
mainly under license from the
Boris Hagelin company in Switzerland.
In 1981, HELL was taken over by Siemens.
In 1990, the graphics-related business was merged with Linotype
and became known as Lynotype-Hell AG. Rudolf Hell died in 2002
at the age of 100.
