by Lionel Curtis, of the American and British delegates to the Paris Peace Conference on 30 May 1919. Curtis had long been an advocate for the scientific study of international affairs and, following the beneficial exchange of information after the peace conference, argued that the method of expert analysis and debate should be continued when the delegates returned home in the form of international institute. Ultimately, the British and American delegates formed separate institutes, with the Americans developing the Council on Foreign Relations in New York.

After being appointed as Director of Studies, Professor Arnold Toynbee became the leading figure producing the institute's annual Survey of International Affairs, a role he held until his retirement in 1955. While providing a detailed annual overview of international relations, the survey's primary role was ‘to record current international history’. The survey continued until 1963 and was well received throughout the Institution, coming to be known as ‘the characteristic external expression of Chatham House research: a pioneer in method and a model for scholarship.’ In 1926, 14 members of Chatham House represented the United Kingdom at the first conference of the Institute of Pacific Relations, a forum dedicated to the discussion of problems and relations between Pacific nations.
