Among a century of books on the life and work of Claude Debussy, the most important biographical studies began with several works by Léon Vallas— Debussy (1862–1918) (Paris: Plon, 1926); Les idées de Claude Debussy, musicien français (Paris: Éditions musicales de la Librairie de France, 1927), translated by Maire O’Brien as The Theories of Claude Debussy (Oxford: University Press, 1929); Claude Debussy et son temps (Paris: F. Alcan, 1932); Achille-Claude Debussy (Paris: Presses universitaires de France, 1944)—and include several by Edward Lockspeiser—Debussy (London: J. M. Dent, 1936), followed by the two-volume study, Debussy: His Life and Mind (London: Cassell, 1962). Equally well regarded is Marcel Dietschy’s La passion de Claude Debussy (Neuchâtel: La Baconnière, 1962), which appeared in English, edited and translated by William Ashbrook and Margaret G. Cobb, as A Portrait of Claude Debussy (Oxford: Clarendon, 1990). Claude Debussy: A Critical Biography now makes its appearance as the most comprehensive biographical study of Debussy in many years. It is much larger than the original French edition, which was in its time François Lesure’s culminating achievement. Updated with new and expertly edited material, the English version now has a dual authorship, which makes it the most detailed examination of Debussy’s protean career yet seen. Lesure, who died in 2001 just as his book was ready for the printer, had been director of the Music Division of the Bibliothèque nationale de France and was the renowned author of several previous studies of Debussy as well as the editor-in-chief of the ongoing edition of the complete musical works, the Œuvres complètes de Claude Debussy (Paris: Durand-Costallat, 1985–). Claude Debussy: Biographie critique (Paris: Librairie Arthème Fayard, 2003) has 460 well-annotated pages with an additional 136 pages given over to Lesure’s catalogue of Debussy’s compositions with “L” numbers, which were later revised. This new translation has been greatly enlarged by Marie Rolf, professor of music at the Eastman School of Music and a member of the editorial team of the Œuvres complètes, for which she also edited the score of La mer. Rolf had worked closely with Lesure for sixteen years and was able to make use of his research materials after his death. Her work has also benefited from the appearance of many new additions to the corpus of Debussy documentation in the sixteen years since Lesure’s biography was published, including a revised edition of Debussy’s Correspondance, 1872–1918 (Paris: Gallimard, 2005), which had previously appeared as Correspondance, 1884–1918 (Paris: Hermann, 1993), this resource being just one of many from which Rolf was able to derive more than two thousand notes and references. Lesure did not number the thirty-four chapters of his book. For the English version, Rolf has reordered and combined some of these and numbered them with new titles (twenty-nine in all) and some new subheadings. [End Page 83] The subtitle of the book is precise: this critical biography is very much a biography of the abundant critical writing about Debussy, by such able writers as Paul Dukas and Louis Laloy. Readers familiar with la presse musicale usually know what to expect; this book reveals the surprising degree of sympathetic understanding of Debussy’s art in France in his own time, and to an extent elsewhere as well. Where Lockspeiser, in two well-documented volumes, sought to place Debussy’s thought and musical aesthetic within the context of the artistic life of la belle époque, Lesure’s approach to Debussy’s life is more closely tied to the composer’s daily existence and events—especially concert life—with which Debussy was directly involved as composer and performer, and obliquely (as well as monetarily) as a well-known and barbed critic...
