Brother Azarias (Patrick Francis Mullany) (b. near Killenaule, County Tipperary, Ireland, 29 June 1847) was an Irish-American educator, essayist, littérateur, and philosopher.
His education began at home, and after his family moved to Deerfield, New York, U.S.A., continued in the union school of that place, and subsequently in the Christian Brothers' Academy at Utica. Believing himself called to the life of a religious teacher, he entered the novitiate of the Brothers of the Christian Schools, in New York City, on 24 February 1862.
He taught in Albany, New York City, and Philadelphia until 1866, when he was called to the professorship of mathematics and literature in Rock Hill College, Ellicott City, Maryland. Gradually his interests were absorbed by literature and philosophy, which, with pedagogy, continued to hold them until the end of his career. From 1879 to 1886 he was President of Rock Hill College.
Then followed two years of research in European libraries, chiefly those of Paris and London. On his return to the United States, he became professor of literature in De La Salle Institute, New York City, and remained such till his death at the Catholic Summer School, Plattsburgh, 20 August 1893.
He was a frequent contributor to the Catholic World, the American Catholic Quarterly Review, and the American Ecclesiastical Review, and his name appears in the files of the Educational Review and of the International Journal of Ethics. His lectures include:-"The Psychological Aspects of Educations", delivered before the Regent's Convocation, University of the State of New York, 1877; "Literary and Scientific Habits of Thought", before the International Congress of Education, 1884; "Aristotle and the Christian Church", before the Concord School of Philosophy, 1885; "Church and State", before the Farmington School of Philosophy, 1890; "Religion in Education", before the New York State Teachers' Association, 1891; "Educational Epochs", before the Catholic Summer School, 1893. At the time of his death, he was engaged in preparing a History of Education for the International Education Series.
