Dr. Sanford Kuvin, a physician and leading researcher in infectious and tropical diseases and founder and chairman of a Hebrew University center in the field that was named for him, died in Florida on Saturday. Kuvin lived both in Jerusalem and in the US with his wife Gabrielle, to whom he was married for 55 years. They had spent several months each year in the capital since 1971. The Sanford Kuvin Center for the Study of Infectious and Tropical Diseases is the world’s leading research center in the world for malaria and other infectious diseases. In 2012, the center was designated by the Health Ministry as the country’s national laboratory for leishmaniasis, the debilitating skin disease spread by certain sandflies.
