Dear Melanie and Richard,
I knew Charles at the University and worked in the Library Systems unit. Among many memories of Charles I recall Charles' generosity in inviting me to take walks with him at the lunch hour. Among memories of such walks several visits to the then recently opened Smart Museum at the University not far from the Regenstein Library stand out in my mind. I also remember Charles for asking the most basic, important, and fundamental questions in every meeting he attended, asked with a smile, "who called this meeting" and "why are we having this meeting". I was personally out of touch with Charles after I left the city and the University much to my regret. I am sure I am not alone in being touched by his humanity, wit, intelligence, and fundamental goodness. He leaves us with good questions: "why are we here; what are we doing?"
