Joseph J. Greenbaum (1924-2011), a specialist in experimental psychology, joined the Graduate Faculty of the New School for Social Research in 1957 and was appointed full professor in 1962. He also served as dean of the Graduate Faculty from 1966 to 1979. This collection contains documentation of Greenbaum's courses in the Psychology Department and administrative files from his role as dean.

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 Schools of Public Engagement was formed in 2011 with the reorganization of the New School for General Studies. As of 2016, the division consisted of: the Bachelor's Program for Adults and Transfer Students (BPATS); the School of Languages; the School of Media Studies; the Milano School of International Affairs, Management, and Urban Policy; and the Creative Writing Program. The collection also holds the 1991-2008 records of the World Policy Institute. Dating largely from the 1990s until 2014, these records contain correspondence, memoranda, reports, budget and financial material, and faculty and personnel files relating to the administration and governance of the Schools of Public Engagement and their predecessor programs, departments, and schools. Some files are restricted. Please email archivist@newschool.edu for details.
