As president of Boston University, Marsh oversaw the building of a new campus, the merger of Sargent College into the university, and the founding of the School of Social Work the School of Nursing, the School of Public Relations (now the College of Communication), and the General College.
Marsh was a strong proponent of prohibition and advocated for its retention in the 1920s. He was also not a fan of New York (much preferring Boston), so much so that his comments on the city once caused New York Mayor Jimmy Walker to hold a press conference to condemn them.[1]
