RAC-KG is a knowledge graph, stored in a Neo4j database, created from approximately 12,000 pages of typed, paper, analog records from the Rockefeller Foundation (RF) collection. The knowledge graph covers the activites of RF's Natural Sciences division between the years of 1932 and 1941 as documented in two primary types of source archival material - the daily activies of Natural Sciences division oficers, as documented in what are referred to as Officer Diaries and Minute Books from Board and Executive Committee meetings which document where RF actually granted money for work in the Natural Sciences. Some additonal source archival material is also contained, but the two primary sources drive the vast majority of entities and relationships contained in the graph.
