Théodule Charles Devéria (; 1 July 1831 – 31 January 1871) was a French photographer and Egyptologist who lived in the 19th century. He is known for his collaboration with Auguste Mariette. His younger brother was Gabriel Devéria. Life Théodule Charles Devéria was born in Paris on 1 July 1831, son of the painter Achille Devéria. In 1843 he met the Egyptologist Émile Prisse d'Avennes, who instilled in him an interest in the subject that was confirmed during a visit to the Leiden museum in 1846. He studied Coptic and Arabic, and attended the Collège de France where he was taught by Étienne Marc Quatremère. He entered the Cabinet of Prints in 1851, where his father was the preserving assistant, and where he learned photography. In 1855 Devéria created lithographs for publication from a set of negatives of photographs made in Egypt of excavations in Thebes. That year he joined the Louvre's Department of Egyptian Antiquities with the task of cataloging the many objects that Auguste Mariette had discovered during his excavations and sent to France. In 1856 he illustrated Mariette's Choix de monuments et de dessins découverts ou exécutés pendant le déblaiement du Sérapéum de Memphis. In December 1858 Devéria left for Egypt to help Mariette read inscriptions in Cairo and its surroundings. He tried to accurately document the archaeological sites using drawings, stampings and photographs. His calotype pictures from this trip are often poor in quality, showing a lack of technical skills. In 1860 he was appointed preserving assistant at the Louvre's Department of Egyptology. He revisited Egypt in 1861–62, traveling up the Nile to Philae at the First Cataract, and into Nubia to the Abu Simbel temples. After returning he helped Mariette prepare descriptions of the excavation in Egypt in 1850–54 for publication. In November 1864 Devéria met the future oriental scholar Arthur Rhoné (1836–1910). A month later Devéria, Rhoné and some friends sailed to Egypt, where they visited Alexandria, Cairo, Memphis, and saw the work on the Suez Canal by Ferdinand de Lesseps. Devéria made drawings and took photographs that were reproduced in an album of 77 plates. The party went on to the Holy Land, Damascus and Istanbul. Devéria made a fourth and last visit to Egypt in 1865-66, traveling with Mariette. In 1868 he was made a knight of the Legion of Honor. He died in Paris on 31 January 1871. The renowned Sir
