Eamon Duffy (born 9 February 1947, Dundalk) is an Irish Professor of the History of Christianity at the University of Cambridge, and former President of Magdalene College.
He describes himself as a "cradle Catholic" and specializes in 15th to 17th century religious history of Britain. He is also a member of the Pontifical Historical Commission. His work has done much to overturn the popular image of late-medieval Catholicism in England as moribund, and instead presents it as a vibrant cultural force. On weekdays from 22 October to 2 November 2007, he presented the BBC Radio 4 series 10 Popes Who Shook the World[1] - those popes featured were Peter, Leo I, Gregory I, Gregory VII, Innocent III, Paul III, Pius IX, Pius XII, John XXIII, and John Paul II.
Professor Duffy is a fellow and former president of Magdalene College, Cambridge.
