On 25 March 1945, Johannes Cornelis van Houwelingen was born in Rotterdam, beginning a career that would place him at the forefront of medical statistics within the Kingdom of the Netherlands. He dedicated decades to advancing mathematical understanding, leaving behind a scholarly legacy centered on survival analysis and empirical Bayes rules until his death in 2026.
Academic Foundations and Early Career
Van Houwelingen completed his education at Utrecht University, where he graduated in 1968 with a major in mathematics and minors in theoretical physics and mathematical statistics. Following a brief tenure at the Institute for Mathematical Statistics, he gained industrial experience at Philips starting in 1969. He returned to academia to earn his PhD in 1973 under the supervision of Gerard Jan Leppink. His doctoral dissertation examined empirical Bayes rules applied to the continuous one-parameter exponential family.

The core of his professional life occurred at Leiden University, where he served from 1963 until his retirement in 2009. In 1986, he received an appointment as a professor, focusing his efforts on the complexities of medical statistics. During this period, he became a member of the American Statistical Association and was recognized as a Fellow of the organization in 2001. His contributions to the field were formally acknowledged in 2008 when he was made a Knight of the Order of the Netherlands Lion.
Research and Academic Contributions
His scholarly work primarily investigated survival analysis, a critical component of biostatistics. Throughout his career, he authored significant texts in the field, including the 1993 volume Inleiding tot de medische statistiek, co-authored with Theo Stijnen and Roel van Strik. Later in his career, he focused on dynamic prediction and survival analysis, co-authoring Dynamic Prediction in Clinical Survival Analysis with Hein Putter in 2011 and the Handbook of Survival Analysis with John P. Klein, Joseph G. Ibrahim, and Thomas H. Scheike in 2013. He continued publishing research as an emeritus professor until 2024.
