The Seven Sisters is a loose association of seven liberal arts colleges in the Northeastern United States that are historically women's colleges. They are Barnard College, Bryn Mawr College, Mount Holyoke College, Radcliffe College, Smith College, Vassar College, and Wellesley College. All were founded between 1837 and 1889. Four are in Massachusetts, two are in New York, and one is in Pennsylvania. Radcliffe (which merged with Harvard College) and Vassar (which is now coeducational) are no longer women's colleges.
Irene Harwarth, Mindi Maline, and Elizabeth DeBra note that "Independent nonprofit women’s colleges, which included the 'Seven Sisters' were founded to provide educational opportunities to women equal to those available to men and were geared toward women who wanted to study the liberal arts". 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). Mount Holyoke received its collegiate charter in 1888 and became Mount Holyoke Seminary and College. It became Mount Holyoke College in 1893. Vassar, however, was the first of the Seven Sisters to be chartered as a college in 1861.
