Friends will remember Cy for his lively conversation over gourmet dinners and his endless, detailed knowledge about a variety of topics. He was a powerful intellectual, but he could relate his knowledge in a down-to-earth way, which made him an excellent teacher. He adored his family and enthusiastically supported their interests. Cy was an extraordinarily caring husband, father, friend, teacher and mentor. He will be missed dearly by all.
