Marcel Cohen (1884-1974) was a French linguist specializing in Chamito-Semitic languages, founder of sociolinguistics and pioneer in the study of slang and children's language. His archives were deposited by his heirs in 1986 at the Institut d'études sémitiques du Collège de France (now the Bibliothèque du Proche-Orient ancien), before becoming part of the Collège's archives. The inventory is now online and available to all researchers.
