Barnard College is a private women's liberal arts college, an affiliated college of Columbia University, and a member of the Seven Sisters. Founded in 1889, Barnard has been affiliated with Columbia since 1900. The 4-acre (1.6 ha) campus stretches along Broadway between 116th and 120th Streets in the Morningside Heights neighborhood in the borough of Manhattan, in New York City. It is adjacent to Columbia's campus and near several other academic institutions and has been used by Barnard since 1898. Barnard was founded to provide an education for women comparable to that of Columbia and other Ivy League schools, most of which admitted only men for undergraduate study into the 1960s. The college was named after Frederick Augustus Porter Barnard, an American educator and mathematician, who served as the president of the then-Columbia College from 1864 to 1889. Frederick Barnard advocated equal educational privileges for men and women, preferably in a coeducational setting. The school's founding, however, is largely due to the efforts of Annie Nathan Meyer, a student and writer who was not satisfied with Columbia's effort to educate women.
