Peter Paret (April 13, 1924 – September 11, 2020) was a German-born American cultural and intellectual historian, whose two principal areas of research were war and the interaction of art and politics from 18th to 20th century Europe.^[1] He also wrote on related subjects.

Paret was born in 1924 in Berlin,^[2] the son of Hans Paret and Suzanne Aimée Cassirer. On his father's side, he is descended from a French family that emigrated to Germany in 1679. Thirteen of Paret's ancestors, including his great grandfather and grandfather, were Protestant ministers. His father, severely wounded in the First World War, studied philosophy before turning to business, and after the Second World War became head of the firm Beuck and Paret, business consultants. Paret's mother, who began to study medicine after her marriage, came from a Jewish family well known for the past two centuries in manufacturing (weaving looms, steel cables), finance, publishing, and scholarship. Her father, Paul Cassirer, publisher and art dealer, was an important force for modernism in the arts in Germany. The philosopher Ernst Cassirer was her uncle. In 1932, Paret's parents were divorced, and his mother with her young daughter moved to Vienna, where she continued her studies with Sigmund Freud.^[3] Paret followed in January 1933. In the following year, his mother married the psychoanalyst and educational reformer Siegfried Bernfeld and with her husband and children moved to France, and in August 1937 to the United States, where they settled in San Francisco.^[3]

Paret entered the University of California, Berkeley, in January 1942, was drafted the following year, and served in combat intelligence and operations sections of an infantry battalion in the New Guinea and Philippine campaigns and in Korea. In 1946, at the age of 21, he was discharged with the rank of Staff Sergeant, reentered UC Berkeley as a sophomore, and graduated in 1949,^[1] after which he returned to Europe to reconnect with his father and other relatives. His plan to study art history was interrupted by the need to assist his mother during his stepfather's final illness, and it was not until 1955 that he began graduate study, this time in history, at King's College London.

He wrote his dissertation on the Prussian Reform era under Michael Howard, became an early member of the Institute for Strategic Studies, served as Resident Tutor in the Delegacy of Extra-Mural Studies of Oxford University, and in the last year before receiving his degree, began to publish articles on contemporary military thought as well as on recent history, having found important documents in the British archives, including a lost register of a Gestapo prison established after the attempt on Hitler's life on July 20, 1944.

After receiving his Ph.D., in 1960,^[1] Paret returned to the United States as Research Associate at the Center of International Studies, Princeton University, where he spent two years. With John W. Shy, who was then a finishing graduate student at Princeton, he wrote his first book, Guerrillas in the 1960s (New York, 1961), a short work analyzing the nature of irregular warfare and the difficulties it posed to modern, industrialized societies, which was reprinted several times, and came out in an expanded edition the following year.

In 1962, Paret came to the University of California, Davis, as Visiting Assistant Professor. He was promoted to tenure the following year, and to full professor in 1966.^[1] During these years at an innovative, rapidly expanding campus, which he later characterized as the happiest in his academic career, he published a study of the modern French theory of political-military warfare, French Revolutionary Warfare from Indochina to Algeria (New York, 1966), and an expanded version of his dissertation, Yorck and the Era of Prussian Reform (Princeton, 1966), a work combining ideological analysis with the study of operational and tactical doctrine, and prepared the context for his growing interest in the ideas and life of Clausewitz, who as a young officer was an active member of the Prussian reform movement.

In 1969, after a year at the Center for Advanced Study in the Behavioral Sciences, Paret was appointed Professor of History at Stanford University; and in 1977 he became the Raymond A. Spruance Professor of International History there.^[1][2]

In 1976, having written several articles on the life and work of Clausewitz, he published a biography, Clausewitz and the State (now in its third expanded edition), which has been translated into three languages. Paret's work together with Raymond Aron's Penser la guerre: Clausewitz, published in the same year, placed Clausewitz firmly in the history of ideas and politics of the Revolutionary, Napoleonic, and post-Napoleonic periods. Paret and Aron reviewed each other's works favorably, although their perspectives on the subject differed. Unlike Aron, Paret has shown little interest in the influence of Clausewitz's ideas on more recent and contemporary conflicts. He studies him, he has said, as he would study Mozart – for what he has composed, not for how later conductors or opera directors perform his work. The title of Paret's book points to the powerful role the Prussian state played in Clausewitz's life, a power that reappears in the central role of policy and politics in Clausewitz's theories.

The same year the biography appeared, Howard's and Paret's translation of Clausewitz's major theoretical work, On War, was published. Highly praised, it has also received some criticism. The work, now available in five English-language editions, has been repeatedly reprinted. Paret's recent article, “Translation, Literal or Accurate,” in The Journal of Military History, July 2014, outlines the principles he and Howard followed in converting Clausewitz's early 19th century German into modern English – principles of translation that also apply to Paret's and Daniel Moran's subsequent translations of Clausewitz's Historical and Political Writings (Princeton, 1992). A related project was Paret's new edition of Makers of Modern Strategy (Princeton, 1986), which retained three essays from the 1943 original, revised four others, and added twenty-two new essays. The work continues to be widely read and used as a text. It is currently being translated into simplified Chinese, the 14th translation of the work.

Since 1980, when his study of modern art and its enemies in imperial Germany, The Berlin Secession, appeared, Paret has published several monographs and collections of essays in the history of art, three of which have been translated into German. He combined his interests in the history of art and the history of war in Imagined Battles: Reflections of War in European Art (Chapel Hill, 1997), a work dedicated "to the memory of the men with whom I served, and against whom I served, in New Guinea and the Philippines."^[4]

In 1986 Paret became the Andrew W. Mellon Professor in the Humanities at the Institute for Advanced Study in Princeton. He retired in 1997. He continued to write, lecture and publish. Among his recent work is Clausewitz in His Time (New York: Oxford, 2015), an expanded German edition of which, Clausewitz in seiner Zeit, appeared in 2017. He edited a volume of two essays by Hans Delbrueck (1848-1929) and himself, Krieg, Geschichte, Theories, Miles Verlag, Berlin 2018, and besides reviews in The Journal of Central European History and The Journal of Military History published an article on the function of history in Clausewitz's understanding of war in The Journal of Military History, October 2018. He celebrated his 95th birthday in April 2019 but continued to work. For example, an article, expansion of a lecture he gave at Princeton University in March 2019, which develops a new concept of Clausewitz's biography, appeared in the January 2020 issue of The Journal of Military History. A short article "From Document to Interpretation", will appear in the July 2020 issue of the journal. He introduced the 2020 Yearbook of the Clausewitz Research Association in Burg, Germany, and also published an article in the issue.

Paret died in September 2020 at the age of 96.^[5]

Paret was a Fellow of the American Academy of Arts and Sciences, a Member of the American Philosophical Society, which has awarded him its Thomas Jefferson Medal, an Honorary Fellow of the London School of Economics, and an Honorary Member of the German Clausewitz Society, which in 2020 awarded him its Silver Pin of Honor. He has received an honorary doctorate from the Humboldt University, Berlin, as well as three other honorary degrees, and the German government awarded him the Cross, Order of Merit First Class, German Federal Republic (2000), and the Great Cross of the Order of Merit, German Federal Republic (2013).^[1]

In 1993, he was awarded the Samuel Eliot Morison Prize for lifetime achievement given by the Society for Military History^[6] In 2017, he received the $100,000 Pritzker Literature Award for Lifetime Achievement in Military Writing.^[7][8]
