Simmons was founded in 1899 with a bequest by John Simmons, a wealthy clothing manufacturer in Boston. Simmons founded the college based on the belief that women ought to live independently by offering a Liberal Arts education for undergraduate women to integrate into professional work experience. Simmons is a member of the Colleges of the Fenway consortium, which also includes Emmanuel College, Wentworth Institute of Technology, Wheelock College, Massachusetts College of Pharmacy and Health Sciences, and Massachusetts College of Art and Design. Simmons absorbed Garland Junior College in 1976.
Simmons produced its first African American graduate in 1914. Furthermore, Simmons was one of the only private colleges not to impose admission quotas on Jewish students for the first half of the 1900s.
The undergraduate program is exclusive to women, with approximately 1800 students enrolled in the 2012-2013 academic year. The graduate schools (Library and Information Science, Social Work, Health Sciences, Business Management, and an Arts and Sciences program that provides degrees in Education, Communications Management, Gender and Cultural Studies and Liberal Arts) are coed, and have about 3,000 students. The school's MBA program is the first in the world designed specifically for women.
Notable women's college Smith College stated in the spring of 2013 that it would deny acceptance to trans women; at the same time a trans woman allowed her acceptance letter into the Simmons class of 2017, in which her activism within the LGBTQIA community was praised, to be posted to tumblr.
