Bowker/Alumni Library stood at the present site of the Steinman Engineering building until 1957.
The Hebrew Orphan Asylum was erected in 1884 on Amsterdam Avenue between 136th and 138th Streets, and was designed by William H. Hume. It was already there when City College moved to upper Manhattan. When it closed in the 1940s, the building was used by City College to house members of the U.S. Armed Forces assigned to the Army Specialized Training Program (ASTP). From 1946 to 1955, it was used as a dormitory, library, and classroom space for the college. It was called "Army Hall" until it was demolished in 1955 and 1956.
In 1946, CCNY purchased a former Episcopal orphanage on 135th Street and Convent Avenue (North campus), and renamed it Klapper Hall, after Paul Klapper (Class of 1904) Professor and the Dean of School of Education and who was later the first president of Queens College/CUNY (1937–1952). Klapper Hall was red brick in Georgian style and served until 1983 as home of the School of Education.
