Paul van Ulsen (14 January 1946 - 23 September 2023)

We are very sad to announce that Saturday, the 23rd of September, Paul van Ulsen passed away.
Paul successfully defended his dissertation entitled E.W. Beth als logicus in September 2000, which he wrote under the supervision of profs Troelstra and Van Benthem.
He has since been a long-term guest at ILLC taking responsibility for the Beth library and ILLC's reference library.
