Teachers Jayne Marriott and Stuart Robinson took a group of A2 Computing students to Bletchley Park on Thursday 20th October. They saw Colossus, the world's first electronic programmable computer, invented during World War II in order to crack the Lorenz code used by the Germans to encrypt commands sent to their forces around the world. The Germans believed their code was uncrackable. However, Mathematician William Tutte found a way to crack the code and Tommy Flowers from the General Post Office was commissioned with the task to make a machine which could speed up the computation. The work done at Bletchley Park is now widely believed to have shortened the war, saving countless allied lives. The Mark 2 Colussus is said to have had an enormous contribution to the success on D-Day in June 1944. All those involved in the work were obliged to keep their role secret for decades afterwards.
The students saw Collosus in operation and toured the Computing museum, trying out Computer Games from the past (which their Computing teachers may have once played) and viewing old hardware such as the magnetic disk that Toby Jackson is posing next to.
