Alexander Passerin d'Entreves, Serena Professor of Italian Studies at the University of Oxford, will replace Carl J. Friedrich, Eaton Professor of the Science of Government, as instructor in Government 106b next spring. Friedrich will be on leave of absence in Europe.

The appointment is, at present, unofficial, pending the approval of both the Corporation and Oxford University.

It was learned last night that d'Entreves, one of the foremost political historians in the world, would assume teaching duties in the course which now uses one of his books, Natural Law, An Introduction to Legal Philosophy, as one of its principal texts.

D'Entreves, a Fellow of the Royal Historical Society, has specialized mainly in political history of Italy, and has written such books as Dante as a Political Thinker, Reflections on the History of Italy, The Medieval Contribution to Political Thought: Thomas Aquinas, Masilus of Padua, Richard Hooker, and Aquinas--Selected Political Writings.

Much of d'Entreves' writing has been done in Italian, both in books and periodicals, and he has been a regular contributor to many British political and historical magazines.

At Harvard, the course he will teach is concerned mainly with "political thought and jurisprudence from the Renaissance to the nineteenth century," the subject of much of d'Entreves' writing and study over the past 20 years.

That d'Entreves has a certain amount of the Italian spirit besides just a scholarly interest in that country's culture is shown by the fact that his non-academic interest is "rambling in the Alps." In this sense, his stay in New England will be a bit disappointing, since Mount Washington should not measure up to the Alpine "rambling" standard.
