As late as the 1960s many of the Ivy League universities' undergraduate programs remained open only to men, with Cornell the only one to have been coeducational from its founding (1865) and Columbia being the last (1983) to become coeducational. Before they became coeducational, many of the Ivy schools maintained extensive social ties with nearby Seven Sisters women's colleges, including weekend visits, dances and parties inviting Ivy and Seven Sisters students to mingle. This was the case not only at Barnard College and Radcliffe College, which are adjacent to Columbia and Harvard, but at more distant institutions as well. The movie "Animal House" includes a satiric version of the formerly common visits by Dartmouth men to Massachusetts to meet Smith and Mount Holyoke women, a drive of more than two hours. As noted by Irene Harwarth, Mindi Maline, and Elizabeth DeBra, "The 'Seven Sisters' was the name given to Barnard, Smith, Mount Holyoke, Vassar, Bryn Mawr, Wellesley, and Radcliffe, because of their parallel to the Ivy League men's colleges."
