C. J. (Cornelis Johan) Koning

Born in 1863, C. J. Koning is identified in library and public-domain book records as Cornelis Johan Koning. He is best known for scientific writing rather than fiction, and his surviving works show a strong interest in agriculture, microbiology, and the chemistry of plant-related processes.

One of his best-known books, Der Tabak: Studien über seine Kultur und Biologie, studies tobacco from several angles, including its cultivation, structure, and fermentation. Records for other works also connect him with research on fungi and humification, suggesting a broader interest in the microscopic life and chemical changes involved in soils and crops.

Although easily available biographical details are limited, the published record presents him as a serious researcher working at the intersection of plant science and microbiology. His writing is a good example of the period when modern agricultural science was beginning to connect field practice with laboratory investigation.
