Thriving in the world of wartime codebreaking took more than just smarts and skill.

Tact, diplomacy and organisational talent were needed to achieve results and navigate the fractious politics of the intelligence community.

In these circumstances even the most shining of lights could be overshadowed by events. The achievements of outstanding talents could be almost lost to history, as the subject of this month’s podcast proves.

In this episode - the second in our 'Focus On' series about remarkable figures in wartime codebreaking - we are joined by Research Officer Dr Thomas Cheetham. He brings a personal insight into the career of Josh Cooper, the head of Bletchley Park’s Air Section. Cooper was an intelligence pioneer, the legacy of whose tireless wartime work has been eclipsed by his eccentric personality.

Our thanks go to Dr Ben Thomson for voicing our historical documents.
