French prehistorian and synthesizer of archaeological knowledge. He was born into a silk‐weaving family and became interested in archaeology through an uncle, Gabriel Bulliot, who was excavating at Mont Beauvray. Joseph later took over his uncle's work and published the results in 1901. At the age of 37, however, he gave up his part in the family business and devoted himself to archaeology. He was the author of the first three volumes of the Manuel d'archéologie préhistorique, celtique et galloromaine (1908–13, Paris: Picard) which cover the prehistory and protohistory of France and adjacent areas of Europe. Déchellette was killed in action in the early days of WW1 and so never completed the third volume of his work, a task that was taken up by Albert Grenier. In 1915 Déchellette was posthumously awarded the Prix Lambert by the French Academy.
