The Carnegie Endowment for International Peace established Le Centre Européen de la Dotation Carnegie pour la Paix Internationale in Paris as part of its Division of Intercourse and Education (Division des Relations et de L'Education) in 1912. The Centre was founded with an Advisory Council composed of representative and distinguished statesmen and public leaders of Europe and Asia. An Executive Committee was appointed from this Council with the authority to carry out the work of the Division abroad. The Centre Européen Records (1911-1940, 316 boxes) consist of correspondence; clippings; meeting minutes, agendas, and transcripts; lectures in typescript and printed form; memoranda; financial documents; books, pamphlets, speeches, reports, and brochures in typescripts and printed versions; invitations; maps; posters; architectural plans and drawings; and photographs, which document the founding, administration, and activity of the Centre Européen specifically and, in a more general sense, the work of the Carnegie Endowment in Europe.
