The "Seven Sisters" refers to a group of seven private liberal arts colleges in the Northeastern United States that were historically women's institutions of higher education.. Radcliffe College shared a common and overlapping history with Harvard College from the time it was founded as "the Harvard Annex" in 1879. Harvard and Radcliffe integrated genders in 1977, but Radcliffe continued to be the sponsoring college for women at Harvard until the entities officially merged in 1999.
The colleges also offered broader opportunities in academia to women, hiring many female faculty members and administrators.
Early proponents of education for women were Sarah Pierce (Litchfield Female Academy, 1792); Catharine Beecher (Hartford Female Seminary, 1823); Zilpah P. Grant Banister (Ipswich Female Seminary, 1828); and Mary Lyon. Lyon was involved in the development of both Hartford Female Seminary and Ipswich Female Seminary. She was also involved in the creation of Wheaton Female Seminary (now Wheaton College, Massachusetts) in 1834. In 1837, Lyon founded Mount Holyoke Female Seminary (Mount Holyoke College). Barnard president Debora Spar said in 2012 that "the relationship is admittedly a complicated one, a unique one and one that may take a few sentences to explain to the outside community". Outside sources often describe Barnard as part of Columbia; The New York Times in 2013, for example, called Barnard "an undergraduate women's college of Columbia University". Barnard graduates receive Columbia University diplomas signed by both the Barnard and the Columbia presidents.
As with Bryn Mawr, Mount Holyoke College, Smith College, and Wellesley College decided against adopting coeducation. Mount Holyoke engaged in a lengthy debate under the presidency of David Truman over the issue of coeducation. On November 6, 1971, "after reviewing an exhaustive study on coeducation, the board of trustees decided unanimously that Mount Holyoke should remain a women's college, and a group of faculty was charged with recommending curricular changes that would support the decision." Smith also made a similar decision in 1971. Two years later, Wellesley also announced that it would not adopt coeducation.
