Richard Pipes and Marc Raeff were two of the most prolific and influential historians of Russia that America ever produced. They met at Harvard in 1946 and went on, for most of the following six decades, to debate history, share ideas, comment on each other's work, and inspire one another intellectually. In Pillars of the Profession: The Correspondence of Richard Pipes and Marc Raeff, Jonathan Daly presents the 158 letters these scholars and friends exchanged from 1948 until 2007. Thoughtful introductory and concluding essays, detailed annotations, a wealth of photographs and other illustrations, a chronology of major events, and four maps make this volume an important addition to Russian historiography.
