It was with great sadness that I learned of the passing of Hasso. Having worked for him in designing, building and testing his mass spectrometer instruments that went to Venus, Jupiter, Mars and Titan it was always a privilege to know I was working for one of the world's top scientist/engineer. He was always a demanding boss who insisted on perfection for his scientific endeavors but with great compassion for those on his team.
My deepest sympathy to Helga Niemann and family. Hasso was a great scientist, boss, mentor, friend, and human being. I feel privileged to have known him and worked for him.
The message below was shared with Hasso Niemann's many friends and colleagues and the NASA Goddard community by the Director of Sciences and Exploration at NASA Goddard.
Our thoughts are with Helga Niemann and the family at this time.
It is with great sadness I have to report the passing of Dr Hasso Niemann, who was a founding father of atmospheric experiments and mass spectrometry at the center
