George Frost Kennan, Professor Emeritus in the School of Historical Studies at the Institute for Advanced Study in Princeton, New Jersey, died yesterday evening at the age of 101.
Professor Kennan, an expert on the diplomatic history of Russia, the Soviet Union and U.S.-Soviet relations, is perhaps best known as the author of the "Long Telegram," dispatched in 1946 to Secretary of State James Byrnes proposing a new approach to U.S.-Soviet relations. The historic 8,000-word message defined the terms of the Cold War.
