Alexander von Kryha and His Encryption Machines
Alexander von Kryha (1891-1955) dedicated at least 15 years of his life to encryption machines of his own development. His machines competed with the Enigma in the 1920s and with Hagelin's machines in the 1950s, but they were much too weak cryptographically to succeed. It is the tragedy of Alexander von Kryha that he made a huge effort in marketing his machines, but did not realize that he was dealing with one of the poorest designs ever. In 1955 Kryha committed suicide, while his company went bankrupt.
