I feel truly fortunate to have been close to Wirt and Virginia in Flagstaff. Wirt was my freshman physics professor and I became his hiking companion in the Grand Canyon for many of the laser experiments. Wirt was always an inspiration, having overcome such obstacles while always beaming with optimism and enthusiasm. He and Virginia were always eager to talk about literature, music, science, etc. I last visited Wirt and Virginia not long before Virginia passed - my young daughter and I saw them in Sun City where they remained full of energy with multiple projects underway. Thank you for the lovely obituary - we shall all miss them.
