1944: Colossus activated by Bletchley Park.

1 February 1944: Colossus activated by Bletchley Park.

Colossus, the world’s first electronic computer, was designed by Tommy Flowers to speed up the code-breaking of Lorenz-encrypted messages between Hitler 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.
