This diary contains the memoranda and letters sent by Raymond Fosdick to his various contacts within the Rockefeller Foundation, specifically recounting conversations and decisions made on the continuation and direction of the Rockefeller Foundation's work in the medical, natural, and social sciences. As the diary covers the pre- and post-WW II period, there is significant discussion on the appropriate actions for the Foundation to take in the continuation of its activities during the war and after in China and Eastern Europe in the early stages of the Cold War. Fosdick also highlights the Foundation's significant contributions to atomic research through Ernest Lawrence and Warren Weaver and his belief that the atomic age would continue to shape the Foundation's work in each of its other departments. This diary also reveals Fosdick's desires to reorganize the Foundation's efforts in all its programs to have greater impact and relevance, especially in the areas of the General Education Board and the Division of Medical Science.
