Irene, This is Doris Rodriguez, we see eachother at mass in Sacred Heart Church & it took me this long to get over the fact that Bill had passed. I cannot say how much Dr. de Groot did for me at work. Everytime he came to the library, he brightened my day, with his smile and politeness that made me feel great. I already missed ya'll already at 7:30 mass on sundays but not as much as I will miss you now. Take care of yourself and know that Frank & I have you in our prayers. You are a GREAT friend.

Dear Irene and all, Janet Ball’s alerting me of Bill’s death triggered my recollection of how hospitable and gracious you were to me during my brief conference-related stay in Galveston so many years ago. As I offer the liturgy for Bill now, please know I pray that the Peace I believe is now his, I trust may be a Source of Consolation, Hope and Peace for you and all who love him. With condolences and blessings,

Dear Irene, Patty, Margaret, Gabby and John It is with great sadness that I learned of Bill's passing. Bill is/was at the top of people who I admire most. His wisdom, curiosity, generosity, modesty, unselfishness and, above all, true friendship have been an inspiration to me, and a model I tried to emulate since I got to know him in Galveston 40 years ago. I looked very much forward to meeting and having dinner with him whenever he went to the annual ATS meeting. It is very hard for me to realize that I will not see him again. Bill loved you, Irene, very much and he was very proud of all his children and loved to talk about them and their accomplishments. You all were a significant topic of conversation whenever we met. My sincere condolences to all of you.
