Peter John Ambrose Calvocoressi (17 November 1912 – 5 February 2010)[1] was a British lawyer, Liberal politician, historian, and publisher.
[1] Calvocoressi's father Pandia had spent the first seven years of his life in Manchester and the next ten at San Stefano (now Yeşilköy, then in the outskirts of Istanbul).
[5] He worked in 'Hut 3', where decrypted Enigma messages were translated and analysed, and Ultra intelligence was prepared for dispatch to commanders in the field.
[6] In summer 1945, he was accredited by British Intelligence to obtain evidence for all four Chief Prosecutors at the International Military Tribunal at Nuremberg.
[4] As a member of the British prosecution team, he cross-examined former German Field Marshal Gerd von Rundstedt during the trial.
Calvocoressi later advised the US Chief Prosecutor (General Telford Taylor), who had been his Bletchley colleague, in some of the American follow-up trials (1946–1949).
[citation needed] During this period (1955-1976), he was for ten years a part-time member of the United Nations Sub-Commission on the Promotion and Protection of Human Rights, and was Chairman of the Africa Bureau, the London Library, Chios Charities, and Open University Enterprises Ltd.
