Charles Tudor Leber was General Secretary of the Board of Foreign Missions of the Presbyterian Church in the U.S.A. The collection contains Leber's correspondence while on tour from 1944-1945 and again in 1953 in Asia, Europe, and Central and South America.

The collection is comprised of papers on medical mission work collected by Forman during his tenure at the Christian Medical Council. The bulk of the material deals with China, although some of the data is drawn from other mission fields, such as the Philippines, India, and Africa.

This collection contains materials compiled by the Missionary Research Library that document foreign mission work in South and Southeast Asia largely during the early 20th century, including committee and conference records, photographs, a diary, manuscript material, reports, correspondence, clippings, and other publications.
