The papers of Leonard P. Ayres (1879-1946) cover the period 1902-1946. The collection consists of journals, correspondence, memoranda, monographs, statistical reports, printed matter, and clippings, and it deals primarily with Ayres's professional life as an educator, statistician, military officer, economist, and businessman. The collection is organized into seven series: Journals , Family Correspondence , General Correspondence , Subject File , Speeches and Writings , Miscellany , and Oversize .
Among his Journals , which Ayres maintained intermittently, the most interesting concern his service as a technical adviser to the Allied Powers Reparation Commission as part of the Dawes Commission, 1924, his trips to Europe, 1927 and 1929, and his service as a consultant to the War Manpower Commission, 1943-1945. The collection also includes a journal kept by Agnes Brooks Young as Ayres's secretary at the War Department and at the War Manpower Commission. In addition to Young's entries, the journal consists of portions dictated by Ayres. In some instances the portions dictated by Ayres duplicate the entries in his journal for the same period.
A small amount of Family Correspondence and an occasional journal entry about his family and friends provide a glimpse of his private life. Ayres, a bachelor, wrote letters to his parents and his siblings May, Ida, Lucy, and Milan. The bulk of the Family Correspondence documents his years as a teacher and superintendent of schools in Puerto Rico (1902-1908). His letters describe life in Puerto Rico and the character of American colonial administration. The General Correspondence relates to Ayres's responsibilities in Puerto Rico, at the Russell Sage Foundation (1908-1920), the Cleveland Trust Company (1920-1946), and as a consultant to the War Department between the wars.
Matters relating to business and education constitute the principal themes in Ayres's Speeches and Writings . The collection includes the lectures he delivered at New York University on educational statistics as well as a number of monographs Ayres wrote for the Russell Sage Foundation on such topics as the teaching of spelling in elementary schools, psychological testing in vocational guidance, and the relation of physical defects to school progress. In 1915-1916 Ayres served as director of the Cleveland Foundation Survey Committee, which sought new ways to improve the educational system in Ohio's largest city. Of the twenty-five reports issued by the survey, Ayres was the author or coauthor of five, and his contributions are included in the Speeches and Writings. The remaining reports are included as part of printed matter under miscellany. The Speeches and Writings file also consists of a small number of articles, speeches, and charts and tables on such subjects as the educational system in Puerto Rico and business activities in the 1920s and during the Great Depression.
The major portion of the collection reflects Ayres's participation in the First World War as the War Department's chief statistical officer, his service to the Allied Reparations Commission as a technical adviser, and his participation in the Second World War as the War Department's coordinator of statistics and a consultant to the War Manpower Commission. The bulk of the Subject File from his wartime service consists of statistical reports prepared under Ayres's supervision for the Army's General Staff. Although there are reports on a variety of topics, the majority are weekly summaries describing the military situation by use of charts, tables, and graphs. The weekly statistical reports for World War II are incomplete, but precede United States entry into the war and cover the period September 29, 1939-November 22, 1941. The Subject File also contains correspondence, memoranda, narrative reports, and printed matter on both war efforts.
Perhaps the most valuable part of the collection concerns the work of the Dawes Commission, which was established in 1924 to examine the problems of postwar reparations and German finance. The committee met in Paris and Berlin to make recommendations to improve economic conditions in postwar Europe. Ayres was appointed one of the technical advisers to the United States delegation, and his contributions are documented in the correspondence, memoranda, and reports that are included in the Subject File. The material also reveals the roles taken by other technical advisers from the United States, France, Great Britain, and Italy as well as the attitude of the Germans toward the extensive investigation of its finances made by the Allies. In addition, the Subject File includes minutes of committee meetings, copies of questionnaires sent to the German government and its responses, copies of the Committee's final reports, and newspaper clippings from the
There is a large amount of printed matter in the Miscellany . This series also includes biographical information, travel vouchers for the period 1940-1945, acknowledgments of receipt of
