X-WR-CALDESC:5 February 1944: Colossus activated by Bletchley Park. \n\nCol
 ossus\, the world’s first electronic computer\, was designed by Tommy Flow
 ers to speed up the code-breaking of Lorenz-encrypted messages between Hit
 ler and his generals. The Lorenz cipher was much more complex than Enigma 
 and could take weeks to decipher by hand. By reducing code-breaking times 
 to a matter of hours\, Colossus enabled the Allies to learn of German war 
 plans almost in real time. The knowledge obtained is widely recognised to 
 have shortened the war and saved countless lives.\n\nA rare piece of one o
 f the original Colossus computers was acquired from the estate of former N
 SA Director LTG William Odom. LTG Odom had contacted Dave D’Auria\, the Ch
 airman of the NCMF Acquisition Committee (AC) to donate the artifact prior
  to his passing. The Colossus memento was presented to LTG Odom by GCHQ in
  1986 to commemorate the 40th anniversary of the NSA-GCHQ partnership.\n\n
 Colossus was one of the world’s first programmable digital computers. Two 
 versions of Colossus were built during WW II to decipher German teleprinte
 r messages encrypted using the German Lorenz cipher machine (codename Tunn
 y). The prototype Colossus (Mark 1) became operational in February 1944. T
 he Mark 2 Colossus\, both faster and simpler to operate\, became operation
 al in June 1944. Eleven Colossus computers were built by the end of the wa
 r. Most of the Colossus computers were destroyed at the end of WW II. GCHQ
  continued to use a few for various computing tasks through the 1950s. A r
 econstructed Colossus Mark 2 is currently on display at Bletchley Park.\n
