Townsend Harris who, besides his many diplomatic accomplishments, had helped found the Free Academy of the City of New York, At this time, the school was referred to as the
Sub-Freshman Class, and its purpose was to bring students of differing educational backgrounds to be sufficiently prepared to attend the Free Academy. It was housed within the James Renwick Jr.-designed Free Academy building on East 23rd Street, in the East Side Manhattan neighborhood of
Kips Bay. Not all Sub-Freshman students went on to the academy, however, as some were simply seeking to be more equipped to enter the workforce. which had in turn been pushed by the educator
Nicholas Murray Butler's desire to see standardized secondary education. The school's introductory year evolved into a fully-qualified program during the early- to mid-1900s, during which time the school became referred to as the
Academic Department. However, the athletic teams from the school were called
C.C.N.Y. Prep. The transition of the school program's length took place over several years, The school's demographic composition would change with the
large-scale immigration from Eastern Europe and elsewhere around the turn of the century. Students were typically immigrants themselves, or the children of immigrants.
Townsend Harris Hall era City College moved to a new campus built in
Hamilton Heights overlooking
Harlem in
Upper Manhattan, a move completed in 1907. to a new building called Townsend Harris Hall, which had been given that name to honor City College's founder. At the same time,
Townsend Harris Hall was also adopted as the name of the school, including in interscholastic sports. There it initially occupied the ninth and tenth floors of the City College School of Business, in a new sixteen-story structure that had opened the year before. As such it was one of the few, and perhaps only, high school in New York City without its own building. Later the eleventh and twelfth floors would be used as well.

Townsend Harris High School, the Preparatory High School of the College of the City of New York. ==Enrollment==
