1872–1960
Remembered as a Dutch scholar with unusually wide interests, he moved from classical studies into philosophy and parapsychology while also publishing literary work. His career gives a glimpse of a learned world where ancient texts, big ideas, and curiosity about the unknown could all meet.

by K. H. E. de (Karel Hendrik Eduard) Jong
K. H. E. de Jong, fully Karel Hendrik Eduard de Jong, was born in Biebrich on February 9, 1872, and died in Zeist on December 27, 1960. He was educated in Germany, Geneva, and The Hague, then studied classical languages at Leiden, where he earned his doctorate in 1900.
He built a long academic life around the ancient world. Sources describe him as a classicist and philosopher who taught at Leiden as a private lecturer, first in the philosophy of the Roman imperial period and later also in parapsychology. His major scholarly work dealt with ancient mystery religions, and he also wrote on Stoicism, Neoplatonism, translation, and the history of occult thought.
DBNL records also show his presence in Dutch literary culture through essays, reviews, and other writings published across several decades. That mix of classical scholarship, independent thinking, and interest in unusual subjects makes him an especially distinctive figure from Dutch intellectual life in the first half of the twentieth century.
