Historien
om opfinderen Alexis Køhl
|
|
A Danish
engineer, Alexis Køhl (1846–1920), invented a number
of cryptographic systems between 1876 and 1919. Some of these systems
were simple, others were more complicated machine systems. Few of
Køhls systems were ever used. One system was used to some extent
in the Nordic countries, but generally Køhl felt that his
“genius” was not properly recognized. There were no sensational
cryptographic innovations in his systems, but some of them were quite
smartly implemented. His first machine systems made use of some of the
earliest mechanical typewriters. All his life Køhl claimed that
his systems were unbreakable. He never made the fortune that he thought
he deserved.
