Harry Gideonse served as chancellor of the New School for Social Research (now The New School) from 1966 to 1975. This collection contains administrative material from his time at the New School for Social Research, and from work with other organizations during this period, including Freedom House and City University of New York. Includes correspondence, financial and fundraising documents, curriculum and conference material.

These records were created by the dean's office of the adult education division of The New School (as of 2022, Schools of Public Engagement), and predominantly reflect the activities of two deans, William Birenbaum and Allen Austill, 1961-1979. A subset of records document the formation of New School College in the 1960s, the Institute for Retired Professionals, and the Physicians Assistant program. A number of files are restricted due to confidentiality.

The collection consists of records originating from the office of Mary Urban, who coordinated fundraising and public relations efforts at the New School in the 1940s and early 1950s, and that of her successor, Margarete Westmann, director of Development from 1958-1962. Materials include memoranda and correspondence, financial statements, budgets, advertising contracts, donor and prospect records, and New School Associates membership records. Also includes event planning materials and invitations, fundraising appeals, minutes, reports, promotional materials, and records documenting the work of the Scholarship Committee and the Graduate Faculty Alumni Association. Part of one file is restricted. Please email archivist@newschool.edu for details.
