completed several major building projects, including the new Cripps Court (not to be confused with the similarly named Cripps at Queens' College, Cambridge). Selwyn College was not the first Oxbridge college to admit women students alongside men, but it adopted the practice relatively early on in 1976. Under Chadwick's years as Master, the numbers of fellows and postgraduates at Selwyn were doubled, greatly increasing the research output of the college. Chadwick took a keen interest in College sports, and was elected to membership of the Hermes Club. Books Chadwick wrote about such issues as the formation of the papacy in the modern world; about Lord Acton; about the Protestant Reformation in the 16th century; about the Church of England in the United Kingdom and elsewhere, and about the secularisation of Europe in thought and culture. He participated in the debate about the role of Pope Pius XII and the Holocaust during World War II. With his brother, Henry, Chadwick edited the Oxford History of the Christian Church (1981-2010), to which he contributed three of its twelve volumes: "The Popes and European Revolution" (1980); "A History of the Popes 1830–1914" (1998); and "The Early Reformation on the Continent" (2003). Chadwick was awarded the Wolfson History Prize in 1981. Owen Chadwick was also General Editor of the Penguin (formerly Pelican) History of the Church, to which he contributed the third volume (The Reformation), the seventh (The Christian Church in the Cold War, 1992) and the last two chapters of the sixth ("A History of Christian Missions", second edition 1986). His brother Henry wrote the first volume in the series (The Early Church, 1967).
