Here are my curriculum vitae and publication list.

And my academic genealogy.




Recent publications

I have recently written a paper on the paintings that Jan Veth made of Jacobus Kapteyn, with the title Pannekoek's Galaxy, which has been accepted by the Journal of Astronomical History and Heritage. It is scheduled to appear in the December 2024 issue. Here is a preprint.

I have recently written a paper on the Galactic work of Anton Pannekoek (1873-1960) with the title Pannekoek's Galaxy, which has been published by the Journal of Astronomical History and Heritage. It appeared in the March 2024 issue. Here is a preprint. with high-res figures.

By invitation by the Journal of Astronomical History and Heritage I have written a 'Reminiscences' article, entitled Excited states and spontaneous transitions: Astronomer, lecturer, administrator, biographer. This autobiographical article concentrates on my scientific career and has been published in the March 2023 issue. The prerint version has sharper photographs.



Recent presentations

This is my presentation (in Dutch!) on the occasion of my retirement after 22 years as chairman of the Board of the Koninklijk Natuurkundig Genootschap on August 25, 2020.






Biographies and publications on the history of astronomy

After my retirement I have written biographies of the founder of my Institute Jacobus Cornelius Kapteyn (1851-1922), after which my distinguished chair in Groningen has been named, and of his student Jan Hendrik Oort (1900-1992), director of Leiden Observatory, who was my PhD thesis supervisor.
These have been in the form of first a comprehesive, scientific biography in English in the Springer Astrophysics and Space Science Library, and later two wider audience versions, one in Dutch (with Amsterdam University Press and Prometheus Publishers) and in English translation in the Springer Biographies series.

Look at a short video on Kapteyn produced at the occasion of the fourth centennial of the university in 2014 (in Dutch with English undertitles), or for those speaking Dutch een ongeveer een uur durend interview.

In 2021 I wrote a paper on the honorary doctorates that were bestowed by Kapteyn and the University of Groningen: Karl Schwarzschild, Annie J. Cannon and Cornelis Easton: PhDs honoris causa of Jacobus C. Kapteyn (preprint). Its was published in the Journal for Astronomical History and Heritage. Here is the journal paper .

And in 2022 I wrote a paper on the history of the Kapteyn Laboratory under Kapteyn's successor van Rhijn: Pieter Johannes van Rhijn, Kapteyns Astronomical Laboratory and the Plan of Selected S'Areas. It was published in the Journal for Astronomical History and Heritage.

Kapteyn died on June 18, 1922. On the occasion of the centenary of Kapteyn's death in 2022, I wrote a Dutch/English booklet on the history of the Kapteyn Laboratory and Institute. It was presented with a short lecture to the Chairman of the Governing Board of Groningen University on June 17. I gave a presentation on Kapteyn on June 18 in Leiden at the old Sterrewacht.
