After obtaining a bachelor’s degree from Rutgers University, Joe met his first wife Jacqueline Leecock at the University of Rochester while pursuing a PhD in Chemistry. They had 11 children together living first in Evanston, Illinois where he was a postdoctoral fellow at Northwestern University before settling on a small farm in Phoenixville, Pennsylvania.  Joe is survived by his second wife of 23 joyous years, Hanni Cohen Weinstock.

Joe was an industrious mensch, actively involved B’nai Jacob Synagogue in Phoenixville, serving as its president and numerous other leadership positions.  He embraced the values of Judaism and worked to ensured that they were passed along to future generations.  He was also committed to the broader community, instrumental in the creation of the Valley Forge Sewer Authority in 1968 serving on its board for 30 years.  His service was recognized by the naming of its administration building in his honor.  In addition, he was actively involved in the local 4-H movement where his children learned civic values, exhibited the farm’s goats and learned about the poultry business among other agrarian projects.  His family feels that he embodied the words of 4-H pledge of devoting one’s head, heart, hands and health to better living.
