• Trinity - the exposure and pursuit of Klaus Fuchs, the most dangerous spy in history
• Lecture Hall I, Physics Institute

Abstract: Trinity was the codename for the test explosion of the atomic bomb in New Mexico on 16 July 1945. Frank tells the story of the bomb's metaphorical father - Oxford professor, Rudolf Peierls; Peierls’ intellectual son, the atomic spy Klaus Fuchs; and the ghosts of the security services in Britain, the USA and USSR. Frank has found new insights from MI5 files in the British National Archives and documents of the FBI and KGB about Fuchs’ treachery. These reveal that in addition to telling the Soviet Union everything about the atomic bomb, Fuchs passed key information about the H bomb much earlier than previously realised. Frank has also discovered that Fuchs was not exposed by J Edgar Hoover’s FBI, as has been believed for decades, but by the cryptographers at GCHQ.The talk is based on Frank's book Trinity, published by Penguin in paperback.
