Schwartz grew up in West Oak Lane and later moved to Wynnefield. He graduated from Overbrook High School and earned a Bachelor of Science degree in chemistry from Penn State University in 1942. He helped found ZBT fraternity at Penn State and later became its president.
Upon graduation from Penn State, he worked for Girard Bank. Shortly thereafter, he went to work for Globe Rubber Products, a family business, where he became vice president of operations.
Schwartz retired in 1969 at the age of 48. However, because of his business acumen, he began Food Sciences Corporation with his son, Robert Schwartz, in 1976. Food Sciences manufactures nutritional food products for both the dietary and supplemental-food industries, growing from nine employees to more than 200. Schwartz continued to work until he was 83.
He gave generously to various charities and had a special fondness for children. He was involved with the Jewish Federation of Greater Philadelphia and attended the Walter H. Annenberg major-gifts dinners.
In the mid-1980s, he started the Schwartz Family Foundation, also with his son Robert, to assist underprivileged children in the United States and Israel.
In addition to his son Robert, Schwartz is survived by his wife, the former Lois Welsh; daughter Nanci Gilberg; and four grandchildren.
