Gregory Pedlow is a professional historian with broad interests in modern European history, especially 19th-century Germany and the Napoleonic Wars. He has published numerous books and articles on German history, the history of NATO and the Cold War, the Battle of Waterloo, and the U-2 spyplane. For the past 20 years he has served as NATO's senior historian at the Supreme Headquarters Allied Powers Europe (SHAPE) near Mons, Belgium, where in addition to his official duties of recording NATO's history and advising senior leaders he is also a popular lecturer/tour guide for the Waterloo battlefield, located just 20 minutes from his office.He received his Ph.D. in European history from the Johns Hopkins University and subsequently taught in the University of Maryland's Overseas Division during an extended residence in Germany. The research and writing he did during this period led to the publication of his first book, "The Survival of the Hessian Nobility, 1770-1870," by Princeton University Press in 1988. He returned to the U.S. in 1980 to become an assistant professor of history at the University of Nebraska and then left academia for government service in 1985, when he joined the History Staff of the Central Intelligence Agency. His long-standing interest in intelligence history was inspired by his service as a US Army military intelligence corps officer on active duty in the early 1970s and afterward in the Army Reserve (from which he retired in the rank of Lieutenant Colonel in 1998). While on the CIA History Staff he was co-author of a classified history which has subsequently been released (with deletions) as "The CIA and the U-2 Program, 1954-1974." In 1989 he was selected to become NATO's senior historian as Chief of the Historical Office at the Supreme Headquarters Allied Powers Europe (SHAPE), also known as the SHAPE Historian. He has published "NATO Strategy Documents, 1949-1969" (NATO, 1997) and a number of articles on NATO history and Cold War subjects such as the Second Berlin Crisis of 1959-1962. While living in Belgium he has become very interested in the Battle of Waterloo and has assembled a large personal library on this subject, including many rare books and manuscripts. He regularly offers battlefield tours and staff rides to the personnel of SHAPE headquarters and distinguished visitors. In recognition of his research and writing on the Napoleonic Wars he was named a Fellow of the International Napoleonic Society. His great knowledge of the Battle of Waterloo and his fluency in German made him an ideal collaborator in Christopher Bassford's project to compare the writings of Clausewitz and Wellington about this battle, which has become the new book "On Waterloo: Clausewitz, Wellington and the Campaign of 1815." After doing his own first English language translation of Clausewitz's "Der Feldzug von 1815" (The Campaign of 1815) in the 1990s (the first one since a rough and incomplete translation done for the Duke of Wellington in 1840), he then merged this with an independently prepared translation done by Daniel Moran in 2004 (who also joined the Bassford project), taking the best features of both translations. Greg's conclusion after working on translating Clausewitz for well over a decade is that "Clausewitz should only be read in translation!" Clausewitz's 19th-century academic style of writing, with its very long sentences containing multiple clauses and unclear pronoun references, is difficult reading even if you are very fluent in German, as Greg is (thanks to 35 years of speaking nothing but German with his wife Gabi, plus of course his academic studies in the German language and German history).
