Frederik H. Kreuger (1928–2015)

Career and research

Kreuger trained and later taught at the Delft University of Technology where he held the post of professor in fields related to insulation and high-voltage engineering. His scientific interests centered on electrical insulation, testing methods and failure analysis — topics important to power systems, high-voltage apparatus and safety engineering. Over several decades he combined academic research with practical consulting and development of measurement techniques that help engineers assess aging and degradation in insulating materials.

Writing, inventions and public work

Besides technical papers and textbooks, Kreuger published general-audience books and novels, including some thrillers. He also held patents and contributed inventions applied in laboratory and industrial test equipment. His biographical and investigative interest led him to study historical cases, most famously the life and methods of Han van Meegeren, a subject on which he produced a well-known account blending technical scrutiny with archival research.

Kreuger was born in Amsterdam in the province of North Holland and spent much of his later life in Delft, where he taught and wrote. He remained active as an author and commentator after retirement, maintaining an interest in both engineering practice and the broader cultural questions that intersect with technical expertise.

Legacy and notable facts

His career illustrates the overlap between applied science and public communication: a researcher who published for peers and general readers, who filed patents, and who investigated historical forensic questions. Kreuger died in January 2015; obituaries noted his dual reputation as a respected technical authority and an engaging writer who brought engineering topics to a wider audience.
