The Rev. Dr. Jerome E. Hayden, O.S.B., 74, a Benedictine monk of St. Anselm's Abbey in Washington and a well known psychiatrist, died Monday in Boston.

Although he had been associated with the Marsalin Institute in Holliston, Mass., for the last 20 years, he had continued to maintain his ties with the Benedictine community here.

Father Hayden had been given permission by his religious superiors in 1957 to found the institute, whose objective is the harmonization of religion and psychiatry.

At the time, he was a professor in the department of psychiatry and psychology at Catholic University and president and director of St. Gertrude's School for Retarded Girls here.

Born in Pittsburgh, Father Hayden was a graduate of the University of Pittsburgh, where he also received a doctor of medicine degree. He also held a doctor of philosophy degree from the University of Luvain in Belgium.

He first specialized in internal medicine but then became interested in psychiatry and took special studies in that field and in neurology at the University of Montreal and McGill University.

Father Hayden joined the Benedictine community of St. Anselm's Abbey here in 1934. It had been founded by a well known psychiatrist, the Rev. Thomas Verner Moore, O.S.B. in 1924.

After completing theological studies at Catholic University, he was ordained to the priesthood in 1947, and became a teacher at Catholic University.

He received specialized training in psychiatry at St. Elizabeths Hospital here., Butler Hospital in Providence, R.I., and the Neurological Institute at Montreal.

He is survived by two nieces in Pittsburgh.
