The records of the Frances G. Wickes Foundation span the years 1911-1978, with the bulk of the material dating from 1955, the year the foundation was created, to 1974, the year after the foundation was terminated. Since Wickes had been a student of C. G. Jung and a practitioner of his theories, the foundation primarily supported institutions and projects related to the Jungian school of analytical psychology. Its records include correspondence, financial material, minutes of meetings, annual reports, corporate papers, and a file on the management of the estate of Frances G. Wickes. Also within the estate administration file is correspondence with Muriel Rukeyser, who helped Wickes with her final publication projects and was her literary executor, and material concerning the estate of the writer Mary Louise Parmalee Peebles. Peebles established a trust fund for Wickes and her son Eliphalet. There is also correspondence from various Jungian analysts and scholars of analytical psychology, including William McGuire.

An addition of administrative and project files was transferred in 2006 to the foundation’s records from the William McGuire Papers. The addition, gathered by McGuire in his capacity as a member of the foundation’s board of directors, contains correspondence, administrative and financial reports, minutes of meetings, printed matter, and miscellaneous items documenting the administration and funding of the foundation’s various programs and projects, including the operation of its financial grant program and the sponsorship of an oral history project devoted to C. G. Jung.
