A man of impressive mental powers, of extraordinary intellectual range, and of exceptional integrity, George Frost Kennan (1904-2005) was an adviser to presidents and secretaries of state, with a decisive role in the history of this country (and of the entire world) for a few crucial years in the 1940s, after which he was made to retire. He then became a scholar who wrote seventeen books, scores of essays and articles, and a Pulitzer Prize-winning memoir. He also wrote remarkable public lectures and many thousands of incisive letters, laying down his pen only in the hundredth year of his life. Having risen within the American Foreign Service and been posted to various European capitals, and twice to Moscow, Kennan was called back to Washington in 1946, where he helped to inspire the Truman Doctrine and draft the Marshall Plan. Among other things, he wrote the 'X' or 'Containment' article for which he became, and still is, world famous (an article which he regarded as t very important and liable to misreading). John Lukacs describes the development and the essence of Kennan's thinking; the, perhaps unavoidable, misinterpretations of his arguments; his self-imposed task as a leading realist critic during the Cold War; and the importance of his work as a historian during the second half of his long life.
John Lukacs is an internationally read and praised historian, the author of more than twenty books, a winner of prizes, past president-elect of the American Catholic Historical Association, and member of the Royal Historical Society of the United Kingdom.
