ABSTRACT

An account will be given of

      now-famous  Enigma  and  the less well-known Lorenz
      SZ40/42  (referred  to  by the Allies as the "Fish"
      machine), and


(ii)  of  the code-breaking machines - which included the
      Colossus,  arguably  the  world's  first electronic
      digital  computer  -  that  were developed in great
      secrecy  in  Britain for use against the Enigma and
      Fish machines.

       Reception to follow in DC 1301.
