The Secret Lives of Codebreakers by Sinclair McKay
During World War II in England, every citizen was expected to do their part in the war effort. Imagine that your job was so secret that you couldn’t tell your family or friends anything about it, or why you weren’t in the armed forces. Then imagine keeping that secret for 30 years. That’s exactly what the codebreakers at Bletchley Park, 50 miles northwest of London, did. Mathematicians, linguists, historians, young aristocrats, engineers, and Wrens were all summoned to Bletchley Park, asked to sign the Official Secrets Act, and worked to break the enigma code the Nazis used in the war for their communications. It was extremely difficult to break one code, and it kept changing. Electronic machines, the Bombe and the Colossus, were developed to help with this work. Assigned rooms in private homes, working different shifts in cold huts in spartan conditions on the grounds of a stately home, eating food that was less than wonderful, several thousand workers, including some Americans, did amazing work. They probably shortened the war by two years, and kept supply convoys from being attacked at sea. The workers, mostly young, also used their creativity and energy to start a number of clubs, from sports to drama, and a number of romances led to marriage. Now a museum, visit Bletchley Park’s website for more information. For a similar book set in Tennessee, read Girls of Atomic City.
