Mary Aloysia Molloy (June 14, 1880 – September 27, 1954) was President of the College of Saint Teresa from 1928 through 1946.
Molloy was born in Sandusky, Ohio, the only child of Irish immigrants. She attended Sandusky High School where she won an essay contest by the Ohio Society of the Sons of the American Revolution. She gained admittance to Ohio State University in 1899 and earned a bachelor's degree in philosophy in 1903, with more honors than anyone else up to that time. Molloy won a fellowship to attend graduate school at Ohio State and completed her master's in English philology in 1905. She continued her studies at Cornell University where she completed her doctorate in 1907. Her doctoral thesis, "The Vocabulary of the Old English Bede", was a concordance to the Anglo-Saxon translation of Bede's Historia ecclesiastica gentis Anglorum.
Following her graduation, in August 1907 Molloy responded to an advertisement seeking a Catholic woman professor in Winona, Minnesota. Working under Sister Leo Tracy, O.S.F., of the Sisters of Saint Francis of Rochester, Minnesota, she taught the freshman curriculum at Winona Seminary. In 1908 she was named the Seminary's assistant principal and began teaching second year courses. The Seminary became the College of Saint Teresa and Molloy was atypical as the lay dean of a Catholic college.
Molloy delivered remarks at the 1917 convention of the National Catholic Education Association (NCEA) on improving women's education. She voiced her concerns over the future of Catholic colleges at the 1918 convention, criticizing the quality of education. She called for fewer institutions that provided stronger curriculum that included medical and legal training. Bishop Patrick R. Heffron of Winona promoted her cause in Rome and Pope Benedict XV awarded Molloy the Pro Ecclesia et Pontifice medal for her service in women's higher education. It was the first time such an honor was bestowed on an American woman for education.
