Thacher was a true Yale man, descended from Rev. Thomas Buckingham, one of the founders of the college that became Yale, and he married the daughter of President Jeremiah Day. Once returned from teaching in Georgia, he left New Haven only for two years of study in Germany and Italy. He seemed to have very little interest in publication and devoted his energies to the affairs of Yale, involving himself in the interests of alumni, faculty, and students. He supported the notion of a graduate program in the humanities and was feared as a college disciplinarian, though he took a sensitive interest in the affairs and concerns of the students. In the words of C. W. Mendell, "A teacher always, rather than an investigator, he seems even to have had a slightly suspicious attitude toward those who gave too much time to research. Even in his teaching he was possibly too much of a disciplinarian and was sometimes thought to stick too rigorously to the grammar. ... He played a larger rôle in the building of modern Yale than that of any one of his contemporaries."
