Enigma and the Codebreakers

Bletchley Park

Bletchley ParkBletchley Park was the home of the secret Government Code and Cypher School. This was the centre of British code-breaking during the war.

The code-breakers were specially chosen from among the cleverest people in the country. Some were brilliant mathematicians or linguists.

By 1944 they had a big team to help them. Seven thousand men and women worked in shifts round the clock in small wooden or concrete buildings known as 'Huts'. Many did repetitive but important jobs like filing or operating the code-breaking machines.

They were not allowed to tell anyone - not even their family or friends - about their work.
