Among the papers of Hugh Trevor-Roper, who died in 2003, was a manuscript to which he had repeatedly turned for more than thirty years, but never published. Attracted by the diverse life and vivid personality of Sir Theodore de Mayerne (1573–1655), the most famous physician in Europe of his time, Trevor-Roper pursued him across national and intellectual frontiers to uncover the details of his extraordinary life. Exploring an array of English and European sources, Trevor-Roper reveals the story of the pioneering Swiss Huguenot doctor who mixed medicine with diplomacy, with political intrigue, with secret intelligence, and with artistic interests at the courts first of Henry IV of France and then of James I and Charles I of England. A true “renaissance man,” Mayerne’s interests were broad, and due to considerable conspiratorial talent, he became a participant in bluff and intrigue at the highest levels. The most ambitious and perhaps the most original of all Trevor-Roper's books, written in his luminous prose, this is a major work of political and intellectual history that presents a whole period in a fresh and vivid light.
Hugh Redwald Trevor-Roper, Baron Dacre of Glanton, was an English historian. He was Regius Professor of Modern History at the University of Oxford. Trevor-Roper was a polemicist and essayist on a range of historical topics, but particularly England in the 16th and 17th centuries and Nazi Germany. In the view of John Philipps Kenyon, "some of [Trevor-Roper's] short essays have affected the way we think about the past more than other men's books". This is echoed by Richard Davenport-Hines and Adam Sisman in the introduction to One Hundred Letters from Hugh Trevor-Roper (2014): "The bulk of his publications is formidable ... Some of his essays are of Victorian length. All of them reduce large subjects to their essence. Many of them ... have lastingly transformed their fields." On the other hand, his biographer Adam Sisman also writes that "the mark of a great historian is that he writes great books, on the subject which he has made his own. By this exacting standard Hugh failed." Trevor-Roper's most commercially successful book was titled The Last Days of Hitler (1947). It emerged from his assignment as a British intelligence officer in 1945 to discover what happened in the last days of Hitler's bunker. From interviews with a range of witnesses and study of surviving documents, he demonstrated that Hitler was dead and had not escaped from Berlin. He also showed that Hitler's dictatorship was not an efficient unified machine but a hodge-podge of overlapping rivalries. Trevor-Roper's reputation was "severely damaged" in 1983 when he authenticated the Hitler Diaries shortly before they were shown to be forgeries.
