I was so sad to learn of the passing of my mentor and friend Hasso B. Niemann. He was a boss who demanded the best from his people and surrounded himself by a team who gave it. I have experienced no more enriching relationship with a colleague than the hours spent in the lab working alongside the Emeritus Dr. Niemann after his retirement. I continue to design and build vacuum systems that preserve his “Prussian sense of symmetry,” and I will always be grateful that he gave a mediocre “cabinet maker” the opportunity to participate in space science. He is sorely missed.
