Mount Holyoke
During these early years, Lyon gradually developed her vision for Mount Holyoke Female which would resemble Grant's schools in many respects but, Lyon hoped, draw its students from a wider socioeconomic range. The college was unique in that it was founded by people of modest means and served their daughters, rather than the children of the rich. She was especially influenced by Reverend Joseph Emerson, whose Discourse on Female Education (1822) advocated that women should be trained to be teachers rather than "to please the other sex."
Mount Holyoke opened in 1837: the seminary was ready for "the reception of scholars on November 8, 1837." Lyon strove to maintain high academic standards: she set rigorous entrance exams and admitted "young ladies of an adult age, and mature character."
In keeping with her social vision, she limited the tuition to $60/year, about one-third the tuition that Grant charged at Ipswich Female Seminary, which was central to her mission of "appeal[ing] to the intelligence of all classes." In order to keep costs low, Lyon required students to perform domestic tasks—an early version of work/study. These tasks included preparing meals and washing floors and windows. Emily Dickinson, who attended the Seminary in 1847, was tasked with cleaning knives. But this would not last. As of 2019, Mount Holyoke now estimates the cost of attending the college to be $71,828 per year. The college offers various forms of financial aid.
Lyon, an early believer in the importance of daily exercise for women, required her students to "walk one mile (1.6 km) after breakfast. During New England's cold and snowy winters, she reduced the requirement to 45 minutes. Calisthenics—a form of exercise—was taught by teachers in unheated hallways until a storage area was cleared for a gymnasium.
Though Lyon's policies were sometimes controversial, the seminary quickly attracted its target student body of 200. Lyon anticipated a change in the role of women and equipped her pupils with an education that was comprehensive, rigorous, and innovative, with particular emphasis on the sciences. She required:
seven courses in the sciences and mathematics for graduation, a requirement unheard of at other female seminaries. She introduced women to "a new and unusual way" to learn science—laboratory experiments which they performed themselves. She organized field trips on which students collected rocks, plants, and specimens for lab work, and inspected geological formations and recently discovered dinosaur tracks.
Lyon developed her ideas on how to educate women when she was assistant principal at Ipswich Female Seminary in Massachusetts. By 1837 she had convinced multiple sponsors to support her ideals and the nation's first real college for women. The town of South Hadley had donated the land and main building. Lyon's layout of the campus provided a widely imitated model for the higher education of women by providing a physical environment that supported a rigorous and comprehensive curriculum equivalent to that of men's colleges. Lyon's innovative goals set her Seminary apart from other female seminaries of the period, offering a curriculum equivalent to those at men's colleges. All the students worked in one building with little privacy. There was close contact with the all-female faculty, and daily self reports on their personal strengths and weaknesses. The college cut staff to the minimum as the 100 or so students each performed one hour of work a day, handling most of the routine chores like cooking and cleaning and maintaining the grounds. Lyon rejected the goal of the men's colleges to promote individualism and independence and instead fostered the collective ideal of a united team of women could match the success of nearby men's colleges like Amherst and Williams. The curriculum allowed women to study subjects like geometry, calculus, Latin, Greek, science, philosophy, and history, which were not typically taught at other female seminaries in the 19th century. Lyon's efforts in founding an institution of higher education for women, despite the economic challenges of the time, paved the way for more women to have the same opportunities for higher education as their brothers.
Mount Holyoke Female Seminary was one of several Christian institutions of higher education for young women established during the first half of the 19th century. Prior to founding Mount Holyoke, Lyon contributed to 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) in 1834. Mount Holyoke Female Seminary was chartered as a teaching seminary in 1836 and opened its doors to students on 8 November 1837. Both Vassar College and Wellesley College were patterned after Mount Holyoke.
According to historian Amanda Porterfield, Lyon created Mount Holyoke to be "a religious institution that offered a model of Christian society for all to see." Students "were required to attend church services, chapel talks, prayer meetings, and Bible study groups. Twice a day teachers and students spent time in private devotions. Every dorm room had two large lighted closets to give roommates privacy during their devotions". Mount Holyoke Female Seminary was the sister school to Andover Seminary. By 1859 there were more than 60 missionary alumnae; by 1887 the school's alumnae comprised one-fifth of all female American missionaries for the ABCFM; and by the end of the century, 248 of its alumnae had entered the mission field.
