It is with great sadness that I announce the death of our colleague Rene Lavendhomme, which occured this Thursday 19 december, some days before his 74th birthday. He has produced nice pieces of mathematics in non-abelian cohomology, categorical logic and synthetic differential geometry. More recently, he published works on philosophy, poetry, psychanalysis and their relations with category theory, in particular topos theory. He founded the category theory group in Louvain-la-Neuve and has been the supervisor of numerous PH.D. thesis, including mine. He was a very friendly person with a constructively critical mind.
