Papers and correspondence, 1948-1980, of Eric Henry Stoneley Burhop, relating to his interests outside his scientific research. The collection comprises biographical material on Burhop's interest in furthering rapprochement between East and West, principally relating to the 'passport case' when, owing to Burhop's involvement in the atomic energy project in 1944-1945, the Foreign Office withdrew his passport on the eve of a visit to the Soviet Union in 1951, causing a libel case arising from his treatment by the press; papers relating to the award of the Lenin Peace Prize to Burhop in 1972; correspondence on the possible nomination of Bertrand Russell for the World Peace Council's International Peace Prize, 1957; and documentation of the Pugwash Conferences on Science and World Affairs, largely the first conference of 1957, including the role of the World Federation of Scientific Workers in its organisation, and manuscript notes of the proceedings. There are no records of his scientific research or scientific correspondence.
