Although chartered as a university, for many years Washington University functioned primarily as a night school located on 17th Street and Washington Avenue in the heart of downtown St. Louis. Owing to limited financial resources, Washington University initially used public buildings. Classes began on October 22, 1854, at the Benton School building. At first the university paid for the evening classes, but as their popularity grew, their funding was transferred to the St. Louis Public Schools. Eventually the board secured funds for the construction of Academic Hall and a half dozen other buildings. Later the university divided into three departments: the Manual Training School, Smith Academy, and the Mary Institute.
