The story of the vital contribution of Polish codebreakers to the cracking of Enigma before World War Two is well known, but what happened to those codebreakers after the invasion of Poland in 1939?

In this episode we follow the long and winding path of the Polish cryptanalysts from Warsaw to London. We also look more widely at the work done by the Polish Government in Exile in the UK to intercept wireless traffic and collaborate with Bletchley Park on signals intelligence.

Head of Content, Erica Munro, is joined by our Research Historian, Dr David Kenyon.

Our thanks go to Dr Ben Thomson for voicing our historical documents.

Against the backdrop of war and secrecy, the Codebreakers of Bletchley Park were often able to enjoy comfort in music. From choirs to orchestras, gramophone evenings to opera, music appears again and again as a recurring motif in the social lives of those working at the Government Code & Cypher School. This episode delves into several different aspects of a topic that we are often asked about, but which frequently gets overshadowed by the showier activities of the BP Drama Group.

Head of Content Erica Munro and Head of Audiences and Programmes Vicki Pipe will discuss some very special musical material from Bletchley Park Trust's archive. Hear from researcher and musician Crispin Lewis about his famous BP relative, composer Herbert Murrill. We are also joined by Research Officer Dr Thomas Cheetham to explore links between music and codebreaking.

Many thanks to Crispin Lewis for allowing us reproduce his performance of Herbert Murrill's 1942 piece 'In Youth Is Pleasure'. www.crispinlewis.com

April 2026

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.
