David Hillhouse Buel Jr. was an American priest who served as the president of Georgetown University. A Catholic priest and Jesuit for much of his life, he later left the Jesuit order to marry, and subsequently left the Catholic Church to become an Episcopal priest. Born at Watervliet, New York, he was the son of David Hillhouse Buel, a distinguished Union Army officer, and descended from numerous prominent New England families. While studying at Yale University, he formed an acquaintance with priest Michael J. McGivney, resulting in his conversion to Catholicism and joining the Society of Jesus after graduation.
