Walter Lippmann was probably one of the best known American journalists dealing with International affairs in the post-War era. He had worked initially as an editor of the «New York World» and in September 1931, he began his career as a columnist for the «New York Herald Tribune». The papers in this project came from his personal papers and manuscipts as opposed to his collection of published work also held in Yale. Lippmann probably met Monnet during the Versailles Peace Conference. For in 1917-1918 Lippmann served as Secretary of a secret organisation created by President Wilson, known as "the Inquiry" to prepare policies for the Paris Peace Conference. This organisation had a significant input into some of the points, dealing with territorial and political issues, in Wilson's 14 points. Lippmann as his correspondence files reveal had a considerable number of contacts in the US administration to keep him extremely well informed on all aspects of American foreign policy. Monnet was aware of the use of having a good rapport with journalists and his relationship with Lippmann remained constant over the years. He also called on Lippmann not just for information but also for advice on the political climate in the US regarding timing for introducing his ideas. Their relationship was in a sense a business one and in 1964 Monnet felt he had to rebuke Lippmann for a piece where he criticised the European Community for having too small a vision of Europe (JMAS/101). In some ways Lippmann's ideas were very different to Monnet's regarding his vision for a united Europe.
