  3. Dear Anita, Monique and the Terwarson family, I just found out the sad news of your father’s passing. I’m so very sorry. I was speaking with our son, Hugo, today about the correlation between music and math. I remember your father speaking of a symposium on that very subject, many years ago. He was a brilliant man and such a good cook – he introduced jackie and me to indian food! I thought to show Hugo his picture and see what I could find out about his work, which led me to his sad passing.I’m so very sorry for your loss. Carolyn Demps
