Dear IAWA Members,

I was very saddened to inform you that Professor Pieter Baas (Leiden, the Netherlands) passed away on April 29th, 2024 at his age of 80.

He served as Executive Secretary of IAWA from 1976 to 1981. Together with Emma van Nieuwkoop, he was the driving force behind the IAWA Bulletin (1970-1979) and the leading scientist of the IAWA Journal almost from the beginning. His great contributions to Plant Anatomy, Forestry, Wood Science, and Wood Anatomy were recognized by the international community.

With Professor Baas's passing, the IAWA loses a remarkable IAWA member.

Professor Baas's cremation will take place later this week in a small circle in Leiden and his extensive obituaries will follow.
