Gerrit van Dijk (14 August 1939, Kampen, Overijssel – 16 April 2022) was a Dutch professor of mathematics and physics.
[2] As a postdoc, van Dijk worked for the academic year 1969–1970 in Princeton, New Jersey at the Institute for Advanced Study.
[1] Van Dijk was a visiting professor at various universities in several countries: Germany (Göttingen), France (Nancy), Japan (Fukuoka), Russia (Tambov), and Sweden (Stockholm).
Van Dijk did historical research on the life and work of the 19th-century Dutch mathematician Thomas Joannes Stieltjes, as well as other Leiden mathematics professors from the past.
This research work resulted in a new issue of Stieltjes's collected works, a portrait gallery in Leiden University's Mathematical Institute, and publication of the book Leidse hoogleraren Wiskunde 1575-1975, which documents the lives of about forty Leiden mathematics professors.
