The F. Tremaine Billings, Jr., Collection is divided into two sections, for the early and later periods of his career. The earlier papers (1936-1944) concern Billings' experiences at Johns Hopkins and as part of the 118th General Hospital in World War II. Included are patient evaluations, writings about Billings' experiences in the 118th Medical Unit in 1942, and a 133-page diary kept by Billings from 1 January 1943 to 14 July 1944 while he served as an Army captain at the 118th General Hospital in Melbourne and Sydney, Australia. Diary entries are primarily concerned with news of fighting at the fronts, medical base camp activities, and Billings' particular interest in malaria. 132 photographs are pasted in the diary, along with a few clippings and some memorabilia. The later papers (1979-1981) consist of records and correspondence of the Johns Hopkins Medical and Surgical Association.
