Inventor of the Hellschreiber – the original fax machine

Rudolf Hell (19 December 1901 – 11 March 2002) was a German inventor who came up with a HF digital mode for sending and receiving text reliably, even with very low signal quality. His contemporary facsimile machine was used for landline press services, and had some use during World War 2, in conjunction with various encryption systems.

He has received numerous awards in Germany for his work, and Hellschreiber is one of the rare historical facsimile machines that is still being used by radio amateurs – Feld Hell Club holds monthly events for communication between members using Hellschreiber.
