The Lewis H. Weed Collection covers Weed's work in the department of anatomy and his tenure as dean and director of the School of Medicine. It contains correspondence, committee records and reports, administrative records, research records, surveys, lectures, and addresses. There is extensive correspondence with Harvey Cushing (1914-1939), William H. Welch (1920-1934), and Florence Sabin (1919-1951). Material related to planning and building new facilities, such as the school of hygiene and the Welch Medical Library, highlight the collection. A special campaign entitled the Half-Century Fund (1924-1926) is documented with supporting lectures and addresses, marking progress and making plans for the future of Johns Hopkins medicine. The collection is strong in documenting Weed's research on cerebrospinal fluid and his other interests in the field of anatomy. Additional Weed correspondence may be found in the papers of Florence Sabin.
