Series 3: Speeches, 1927-1965

Correspondence, journals, notes, oral history transcripts, memoranda, scrapbooks, clippings, subject files, published and unpublished writings and speeches, printed matter, reprints, and photographs (1900-1985; 19.4 l.f.) document Gregg's tenure at the Rockefeller Foundation and his role as a consultant and spokesman on issues related to medical education and public health, particularly during the 1940s and 1950s. They do not include Gregg's Rockefeller Foundation administrative papers, located at the Rockefeller Archives Center.

The bulk of the collection consists of correspondence, of note being his correspondence with fellow Rockefeller Foundation officers such as Robert Lambert, Raymond Fosdick, Dean Rusk, Fred L. Soper, and Robert Struthers, as well as material relating to his consultant work with the Veterans Administration. Much of the correspondence also contains photographs relating to his service with the British army and travels as a Rockefeller Foundation officer. Gregg's Speeches, many of which bear his handwritten annotations, address a wide range of subjects including medical education, the role of foundations in medical research, the concept of giving, and the founders of the Rockefeller Foundation whom Gregg knew personally. In addition, the Writings series contain reports on Gregg's work in the Foundation's European office during the 1920s, and a complete set of his reprints. The Writings by Others sub-series consists primarily of published articles collected by Gregg relating to various aspects of medicine, population dynamics, and his membership in the America First Committee. America First was an organization founded in 1940 to oppose American intervention in World War II; it disbanded after the Japanese attack on Pearl Harbor in December 1941.

The collection also contains biographical and family material spanning much of Gregg's life, which is scattered throughout the Personal and Biographical, Correspondence, and Subject Files series. These materials include a set of journals and scrapbooks from 1908-1940, and correspondence with family members dating from 1901 to Gregg's death in 1957. A substantial portion of the Family Correspondence contains letters between Gregg and his wife Eleanor from 1915-1956. There are also notes for an uncompleted autobiography and commentary on Gregg's interest in the philosophy of philanthropy.
