At Notre Dame, he was Prefect of Discipline (1863-1865), Prefect of Religion (1865-1866), and the President (1872-1874).[1]

He began construction of the university library (now Bond Hall), which was named in his honor.[2] He was amicable and beloved by the student body for his closeness to the needs of students.[3] He died in office, at the young age of thirty five.
