Pierre Bancel was drawn early on to languages and focused on learning a dozen of them, including German, Russian, Hindi, and Kabyle, as well as Classical Latin and Greek. He has earned an MA in Language Sciences from the Université Auguste et Louis Lumiere, Lyon, with an emphasis on comparative linguistics, instrumental phonetics, and fieldwork on Bantu languages. He has worked as a copyeditor for the French dictionary Le Robert, a journalist for various periodical publications, and as a translator by the United Nations in New York, Geneva and Vienna. Bancel translated into French two books by Stanford linguists Joseph Greenberg and Merritt Ruhlen, and has published several dozen research articles in linguistics journals, many of them in the then Harvard‑based Mother Tongue, of which he has been coeditor since 2021. This is his first book, summarizing years of research into language and into how articulated words may have emerged in an originally speechless ape species, turning it into humans in the process.
