Drawing on twenty years of research, this is the definitive biography of Primo Levi. Over the last seventy years, Primo Levi (1919-87) has been recognized as the foremost literary witness of the extermination of the European Jews. In Primo Levi: An Identikit, a product of twenty years of research, Marco Belpoliti explores Levi's tormented life, his trajectory as a writer and intellectual, and, above all, his multifaceted and complex oeuvre. Organized in a mosaic format, this volume devotes a different chapter to each of Levi's books. In addition to tracing the history of each book's composition, publication, and literary influences, Belpoliti explores their contents across the many worlds of Primo Levi: from chemistry to anthropology, biology to ethology, space flights to linguistics. If This Is a Man, his initially rejected masterpiece, is also reread with a fresh perspective. Fundamental themes such as Judaism, the camp, and testimony innervate the book, which is complemented by photographs and letters found by the author in hitherto unexplored archives. This will be the definitive book on Primo Levi, a treasure trove of stories and reflections that paint a rich, nuanced composite portrait of one of the twentieth century's most unique and urgent voices.
