Demiéville was one of the foremost sinologists of the first half of the 20th century, and was known for his wide-ranging contributions to Chinese and Buddhist scholarship. His influence on Chinese scholarship in France was particularly profound, as he was the only major French sinologist to survive World War II.
Demiéville was one of the first sinologists to learn Japanese to augment their study of China: prior to the early 20th century, most scholars of China learned Manchu as their second scholarly language, but Demiéville's study of Japanese instead was soon followed by nearly every major sinologist since his day.
