The first chapter of one 
The first chapter of one of this man's works opens with an analysis of Caspar David Friedrich's Wanderer Above the Sea of Fog, and notes that history is fuzzier than the hard sciences because humans are "molecules with minds of their own"; that work is The Landscape of History. This man strongly criticized William Williams Tragedy of American Diplomacy in an article in which he called for analyzing the effects of American foreign policy on the "Second World". Several of this man's works ushered in the "Post-Revisionist" study of a particular period. Henry Kissinger wrote a glowing review of one of this man's works, which quotes the subject's diary stating "I hate democracy" and details the subject's clash with (*) Dean Acheson as the head of the Policy Planning Staff. This man's work We Now Know adds to his corpus using recently-opened Soviet archives to posit that conditions in the USSR were far worse than believed during the mid-20th century. For 10 points, name this Yale University professor and author of The Cold War: A New History and the Pulitzer-winning George F. Kennan: An American Life.
