Obituary Professor Dipl.-Ing. Herbert Pfeiffer

It is with deep sadness that we bid farewell to Professor Pfeiffer, who has passed away at the age of 90.
His life's work as an architect and university lecturer continues to shape the Department of Architecture and Civil Engineering at the Technical University of Dortmund to this day. With tireless commitment, innovative approaches and a great passion for his subject of planning theory, he inspired generations of students and provided decisive impetus for architecture as well as for the Dortmund model.
His professional expertise was always combined with a special passion for teaching and a human warmth that will be vividly remembered by all who knew him. Many of us think back with gratitude to his clear, profound lectures and seminars, which not only imparted knowledge but also aroused enthusiasm.
In him, we are not only losing a bright mind with vision, but also a committed colleague and mentor. His work will live on in the department and far beyond.
Our condolences go out to his family, his friends and all those who were associated with him.
The Dean, Prof. Dr.-Ing. Mike Gralla
Department of Architecture and Civil Engineering at TU Dortmund University
