I was saddened to read of your Father's passing, and also your mother. As a Master's student just starting my teaching career, your father was such an inspiration. He made sure that he gave us applications for life, and for use in our classrooms. I have never forgotten his kindness, intelligence, and quiet wit, and the great field trips he arranged for us. Your mother was always a gracious hostess for the parties they held for his students. Although it's been 40+ years, I still remember his teachings and passed it on to my students until my retirement in 1997. My sincere condolences to you all. he will long be remembered and missed.
