Over approximately the next two decades, the other schools of the university, which were located at a separate campus at 96 Schermerhorn Street in Downtown Brooklyn, moved out to the new campus in Queens. The last of the schools to relocate to Queens moved there in 1972, bringing an end to the Downtown Brooklyn campus of the university. In 1959, the university established a Freedom Institute to provide lectures and programs that would, in the words of university president Rev. John A. Flynn, focus "attention on the dangers of communism threatening free institutions here and abroad," with Arpad F. Kovacs of the St. John's history department as its director. (A volume of lectures given at the Freedom Institute was edited by Kovacs and published in 1961 as "Let Freedom Ring".) The university also hired the noted historian Paul Kwan-Tsien Sih to establish an Institute of Asian Studies in that same year, and similarly set up a Center for African Studies under the directorship of the economic geographer Hugh C. Brooks.
