G. J. de Groot

Born in 1854 in the Netherlands, Jan Jakob Maria de Groot was a Dutch linguist, ethnographer, and sinologist. He is best known for his deep study of Chinese religion and social life, especially after extended research in China, including time in Xiamen, where he gathered material that shaped much of his later writing.

De Groot taught at Leiden University and became one of the leading European scholars of China in his era. His major works explored religious practice, popular belief, sectarian movements, and the structure of Chinese society, and they were widely used by later historians and scholars of religion.

He died in 1921, but his reputation has lasted because of the scope of his research and the detail of his observations. Even when parts of his scholarship reflect the limits of his time, his writings remain an important early window into how European scholars tried to understand Chinese culture on its own terms.
