Louis-Gilles Delahogue (1739-1827) was a French priest and academic, who was exiled following the French Revolution and moved to Ireland. His surname particularly in French is sometimes written as De La Hogue. Delahogue graduated from the Sorbonne and was a Professor of Sacred Scripture at the University of Paris, Sorbonne and Royal Censor from 1772 until after the revolution. Initially, after the September massacres in Paris in 1792, Delahogue found refuge and employment in London, England, where he spent six years before he moved to Ireland. In 1798, he was appointed the professor of Moral Theology, at the newly established Royal College of St. Patrick, Maynooth, Ireland. In 1801 he moved from Moral Theology to succeed Rev. Maurice Aherne as Professor of Dogmatic Theology.
