In 1882, Thomas wrote a letter to the trustees of
Bryn Mawr College, requesting that she be made president of the university. She was not granted the position, however, as the trustees were concerned about her relative youth and lack of experience. In 1885, Thomas, together with
Mary Garrett, Mamie Gwinn (February 2, 1860 – November 11, 1940), Elizabeth King, and Julia Rogers, founded The
Bryn Mawr School, a prep school in Baltimore, Maryland. The school would produce well-educated young women who met the very high entrance standards of
Bryn Mawr College. In 1894, President Rhoads died, and Thomas was narrowly elected to succeed him on September 1, 1894. Out of respect for President Rhoads's recent death, Thomas was not given a ceremony. She was president until 1922 and remained as Dean until 1908. During her tenure as president, Thomas' primary concern was upholding the highest standards of admissions and academic rigor. The entrance examinations for the college were made as difficult as those at
Harvard University, and pupils could not gain admission by certificate. For the academic curriculum, Thomas emulated the "group system" of Johns Hopkins, in which students were required to take parallel courses in a logical sequence. Students could not freely choose electives. There were also other requirements, including a foreign language requirement that culminated in a sight translation examination proctored by Thomas herself. Overall, the academic curriculum at Bryn Mawr under Thomas shunned liberal arts education, preferring more traditional topics such as Greek, Latin, and mathematics. Thomas and Gwinn lived together at Bryn Mawr College in a small cottage that came to be known as "the
Deanery". "As late as the first decade of the twentieth century, she wrote of her relationship with Mamie in language analogous to marriage. But by the 1920s she faced a different world. The love between women that had once been broadly accepted was now being portrayed in fiction and on the stage as lesbian and deviant." When Gwinn left Thomas in 1904 to marry (a love triangle fictionalized in
Gertrude Stein's
Fernhurst)
Alfred Hodder, a fellow Professor of English at Bryn Mawr College, Thomas pursued a relationship with
Mary Elizabeth Garrett. Thomas blocked the hiring of Jewish teachers, and later worked to remove Jewish candidates from consideration for faculty positions, noting she preferred to have faculty made up of "our own good
Anglo-Saxon stock." She tried to block the admission of Sadie Szold, a Jewish student, to the college. In a speech to the freshman class of 1916, Thomas said: "If the present intellectual supremacy of the
white races is maintained, as I hope that it will be for centuries to come, I believe that it will be because they are the only races that have seriously begun to educate their women." While Thomas claimed that African American students did not apply to Bryn Mawr during her tenure as president, she diverted
Jessie Redmon Fauset, an African American student who received a scholarship to attend Bryn Mawr in 1901, to
Cornell University, and helped pay a portion of Fauset's tuition. In August 2017, Bryn Mawr President Kim Cassidy addressed Thomas' "racism and anti-Semitism' and demands by some that the school drop Thomas' name from several buildings.
"While Thomas had a profound impact on opportunities for women in higher education ... on the academic development and identity of Bryn Mawr, and on the physical plan of the campus, she also openly and vigorously advanced racism and anti-Semitism as part of her vision of the College. Some of you have suggested that the College rename Thomas Library and Thomas Great Hall because of this legacy, and others have suggested making that history explicit in other ways." Thomas retired in 1922, at age sixty-five. She was succeeded by
Marion Edwards Park, who served as a dean at both Simmons and Radcliffe Colleges. The
Bryn Mawr Summer School for Women Workers in Industry, which was founded at Carey's behest in 1921, was a sort of "grand finale" bookending Thomas' legacy as an earlier shaper of the college. Mary Garrett left a considerable fortune to Thomas, who spent the last two decades of her life traveling the world in luxury, including trips to
India, the
Sahara, and
France. ==Death==
