Marc McMenamin, author of Codebreaker: The Untold Story of Richard Hayes the Dublin Librarian Who Helped Turn the Tide of WW2, will deliver a talk about librarian and secret WW2 codebreaker Richard Hayes. Described by MI5 as Ireland’s “greatest unsung hero” and the American Office of Strategic Services as “a colossus of a man”, he covertly led a team of cryptanalysts during WW2 as they worked on the infamous Görtz Cipher – a Nazi code that had stumped some of the greatest minds at Bletchley Park. Richard Hayes was himself something of a dichotomy – mild mannered librarian, academic, loving father and one of World War Two’s most prolific Nazi Codebreakers. Documentary maker Marc McMenamin leads us through the story of his life and work in what promises to be a compelling talk.
