b. 1865
A Dutch writer from the late 19th and early 20th centuries, remembered for exploring Eastern religious and philosophical traditions for a general readership. His best-known surviving work, De wijzen van het Oosten, reflects a wide-ranging curiosity about Brahmanism, Buddhism, Chinese philosophy, and Mazdaism.

by Cornelis Hille Ris Lambers
Cornelis Hille Ris Lambers was a Dutch author active in the early 20th century. Reliable catalog and library-style sources available here confirm him as the author of De wijzen van het Oosten, a Dutch-language work that surveys several Eastern wisdom traditions for readers interested in religion and philosophy.
That book is the clearest surviving marker of his reputation today. It presents Brahmanism, Buddhism, Chinese philosophy, and Mazdaism in an accessible, comparative way, suggesting a writer interested in introducing broad intellectual traditions rather than speaking only to specialists.
Beyond that, the biographical record I could confirm from the sources used here is quite limited. I was not able to verify fuller personal details such as a dependable portrait image, so those are best left unstated rather than guessed.
