Chris was such a wonderful person with an open, loving heart--always caring for his students and supportive of them. Being my "Doktorvater" and greatest mentor, his contributions to my growing as a scholar are very precious. I will always remember him with his generosity and his way of connecting to people and life out of his heart. I am very upset about losing him. Dear Roberta, please accept my deepest condolences. My heart goes with all the family, especially Emma, Quinn, Jon and Tamara. I am thinking of you all.
