The Harry Slattery Papers span the period 1890-1953 with the bulk dated 1928 to 1944. They include correspondence, memoranda, writings and speeches, printed material, clippings, scrapbooks, and indexes. The collection chiefly concerns positions Slattery held during his years of public service and reflect his lifelong interest in conservation. Very few of Slattery's personal papers are included in the collection.
The bulk of the collection relates to Slattery's positions as personal assistant to Harold L. Ickes (1933-1938), as Under-secretary of the Interior (1938-1939), and as administrator of the Rural Electrification Administration (REA) (1939-1944). Other papers concern his service as secretary to Gifford Pinchot (1909-1912), as secretary of the National Conservation Association (1912-1923), as special assistant to Interior Secretary Franklin K. Lane (1917-1918), as a Washington lawyer (1923-1933), and as counsel to the National Boulder Dam Association (1925-1929). There is also information about the Teapot Dome Scandal. While information about the REA is found throughout the collection, information pertaining to the other topics is found chiefly in the Correspondence, Memoranda, Writings and Speeches, Printed Material, and Clippings Series. A typescript of Slattery's autobiography, From Roosevelt to Roosevelt, Washington, D.C., 1948, and information relating to the published work Rural America Lights Up, Washington, D.C., 1940, which is attributed to Slattery, are found in the Writings and Speeches and Scrapbooks Series. Persons studying conservation issues in the United States and the spread of electricity to rural areas would find this collection particularly helpful.
There is extensive material relating to the controversy surrounding the Rural Electrification Administration, tensions between the REA and the National Rural Electric Cooperative Association, whose executive manager was Clyde Ellis, and the conflict between Slattery and the Secretary of Agriculture Claude W. Wickard. Correspondents include Harold L. Ickes, Judson King, Basil Maxwell Manly, Gifford Pinchot, Amos R. Pinchot, John Patrick Grace, Cornelia B. Pinchot, and Philip Patterson Wells.
