I first met Bob some thirty years ago, when we were both working at Ames. We briefly shared an office. I had been doing some work on using infrared lines to explore the composition of galaxies, but it was Bob who was harnessing powerful software tools to help do that work best. His contributions to the field were impressive. Bob always had a (sometime wry!) smile on his face, and welcomed any opportunities to chat, whether about work or life. In fact, when I picture him, that's what I see. His knowing smile. We will miss both his work and his spirit.
