James Buchanan Duke established the Duke Endowment in 1924. The endowment provided funds to form Duke's School of Medicine and Duke Hospital. Duke North opened in 1980 and was connected the older hospital, referred to as the South division, through a personnel rapid transit system (PRT). Construction of this addition corresponded to the construction of the hospital's nearby Communications Center and Medical Library, leading to a degree of overlap between records for both projects. Types of materials in this collection include meeting minutes, planning files, reports, construction notes, blueprints, conceptual drawings, correspondence, reference materials, accounting and revenue records, sound recordings, photographs, photographic slides, and negatives. Materials range in date from 1972 to 1986.
