Dr. Lambertus Hamminga


Adolfo García de la Sienra and Theo Kuipers


Lambertus (Bert) Hamminga was a gentle Dutchman and distinguished scholar (Ph.D. Economics, M.D. Philosophy). Being born in Amsterdam on July 1, 1951, due to Covid he passed away in Beesd, the Netherlands, on April 16, 2021. Until 2001 he was a university lecturer in Tilburg, Netherlands; in philosophy of science, specialized in mathematical modelling, methodology, formal axiomatics and structural analysis of scientific theories. His generous work of organizing the second and third international conference on methodology and philosophy of economics (‘Tilburg I’, July 1987 and ‘Tilburg II’, July 1991), gathered together scholars from the Americas and Europe that eventually gave rise to the International Network of Economic Methodology. His impulse to organize these conferences (with Wolfgang Balzer the first one, and with Neil De Marchi the second one) sprang from the very first conference pioneering the field, organized in Munich in July 1981, by W. Balzer W. Spohn, and W. Stegmüller. Bert’s stimulating role in the rise of the field cannot be overestimated.

His own scientific and philosophic work was mainly devoted to topics in economics and economic methodology (see Bibliography), but he was also interested in the philosophy of culture, with a book comparing Western and African epistemology. His last interest was Spinoza’s Ethics, about which he provided a reference web for students of the Ethica, EthicaWeb. It is referred to in the Stanford Encyclopedia of Philosophy by the Spinoza biographer Steven Nadler.

Until his death he maintained a very lively website,, reporting his life and his scientific and literary studies, partly from his sailing dhow in Africa. He was a consummated Jazz-saxophone player, a passionate classical boat yachtsman, and organiser of JOL112-tournaments. As the family announcement stated (in Dutch): he was an ‘opinionated, colourful, humoristic scientist, philosopher, saxophonist, and above all sailor’.
