Although I had not seen Dr.Faith in many years, I am saddened to learn of his death. Heidi will not remember, but I was her babysitter while I was a student at Penn State. Her parents thought I was remarkable because I took her into the dark back yard to catch fireflies in a jar. Years later, Dr. Faith and I came across each other at the Princeton Pool, and we had several interesting conversations. I send all his family my condolence.
