The correspondence, writings and photographs in this collection document the translations, psychoanalytic practice and scholarship of Gregory Zilboorg, the relationship between Gregory and Margaret Zilboorg (neé Stone) and Gregory Zilboorg's photographic portraiture. Most of the papers date from the 1940s and early 1950s and document Zilboorg's personal life and writings (including translations and writings on the history of psychiatry). The papers illustrate the work of a prominent analyst at a time when psychoanalysis had a significant influence on the New York literary circle in which Zilboorg worked.
Professional correspondence dates mostly from 1940 to1941 and includes incoming, outgoing and third party letters. The topics addressed include Zilboorg's professional travel, speaking engagements, publishing arrangements, financial matters and medical patients. While Zilboorg discusses patient cases in his correspondence, the papers do not include patient records or case files.
