Radcliffe College was a women's liberal arts college in Cambridge, Massachusetts, and was the coordinate college for Harvard University. It was also one of the Seven Sisters colleges. Radcliffe College conferred joint Harvard-Radcliffe diplomas beginning in 1963 and a formal merger agreement with Harvard was signed in 1977, with full integration with Harvard completed in 1999. Today, Radcliffe's campus functions as a research institute within Harvard, the Radcliffe Institute for Advanced Study, and former Radcliffe student housing has been incorporated as residential houses of Harvard College. The "Harvard Annex," a private program for the instruction of women by Harvard faculty, was founded in 1879 after prolonged efforts by women to gain access to Harvard. Arthur Gilman, banker, philanthropist and writer, and son of Winthrop Sargent Gilman, was the founder of Radcliffe College. The school was called in memory at the first female donor, Ann (Radcliffe) Mowlson. Ada Comstock, a leader in women in higher education, who hailed from the University of Minnesota and Smith College, was the first president.
