Dr. Hendrik Jan Zweerink, 86, known to most as Hans and to the lucky few as “Opa,” passed away peacefully on April 13 at home under hospice care due to complications from Parkinson’s Disease.
Born in Hilversum, the Netherlands, Hans’ early life was shaped by the hardships of World War II and the German occupation of his country. After completing his education including college in Holland, he applied to Cornell University’s graduate food science program on a whim, and was accepted. That same year, he left Holland by boat, arriving in New York with a suitcase, a thick Dutch accent, and a tenacious spirit.
