John Hugh "Adam" Watson CMG was a British International relations theorist and researcher. Alongside Hedley Bull, Martin Wight, Herbert Butterfield, and others, he was one of the founding members of the English school of international relations theory.
He was born John Hugh Watson and educated at Rugby and King's College, Cambridge. As an undergraduate at Cambridge, where he read History, Watson was taught by Herbert Butterfield. After a period of travel in central Europe in the late 1930s, he joined the British Diplomatic Service in 1937, taking the nickname Adam "after noticing that every head in the Foreign Office seemed to turn when someone asked for John". During the Second World War he acted as a liaison with the Free French in Cairo, played an unknown role in the Balkans, based in Bucharest, and was finally posted to Moscow, where he witnessed the victory celebrations of 1945, standing alongside the Soviet Politburo and where he remained for the next four years.
