 In 1957, a year after he had married Aline Halban (née de Gunzbourg), Berlin was elected Chichele Professor of Social and Political Theory at Oxford (his inaugural lecture, delivered in 1958, was Two Concepts of Liberty). Later in 1957 he was knighted. He resigned his chair in 1967, the year after becoming founding President of Wolfson College, Oxford (which he essentially created), a post from which he retired in 1975. In his later years he hoped to write a major work on the history of European Romanticism, but this hope was unfulfilled. From 1966 to 1971 he was also a visiting Professor of Humanities at the City University of New York, and he served as President of the British Academy from 1974 to 1978. Collections of his writings, edited by Henry Hardy (sometimes with a co-editor), began appearing in 1978: there are, to date, fourteen such volumes (plus new editions of four works published previously by Berlin), as well as an anthology, The Proper Study of Mankind, and a four-volume edition of his letters. Berlin received the Agnelli, Erasmus and Lippincott Prizes for his work on the history of ideas, and the Jerusalem Prize for his lifelong defence of civil liberties, as well as numerous honorary degrees. He died in 1997.
