Aidan Kavanagh was a Roman Catholic Benedictine monk and liturgical scholar. He was 77 years old when he died in 2006. He taught at Yale for many years. Before Yale, he had founded the doctoral program in liturgical study while at Notre Dame. And before he was a Roman Catholic, he was an Episcopalian. He grew up in Saint Paul’s Church, Waco, Texas. He attended the University of the South. His obituaries that I found online avoid the question of when he became a Roman Catholic. He became a novice of Saint Meinrad Archabbey in southern Indiana in 1957. His life was spent at universities.
