In 1950, Sherman joined the education faculty at the University of Liberia. Mary Antoinette Brown was appointed Dean of the Teachers' College at the
University of Liberia in 1958, and later vice president for academic affairs (1975-1978). She was president of the University of Liberia from 1978 to 1984. During her tenure as president, the university saw expanded facilities and programs, and improved scholarship funding. She also worked on behalf of faculty members against government interference. In 1980, President
Samuel K. Doe attempted to appoint Sherman as his secretary of education, but she declined the offer. In 1984, Sherman was dismissed from the university after the Liberian Army violently invaded the campus, and effectively shut down the school for several years. She relocated to the United States in 1986, where she helped to found the University of Liberia Alumni Association. She also wrote a biography of her mother, published in 2005. In 2016 a second woman,
Ophelia Inez Weeks, took on her role of leading the University of Liberia. At her inauguration President Sirleaf lauded the ground breaking job that Brown-Sherman had achieved. ==Personal life==
