At Princeton, he worked in Commons, joined Cloister, and majored in chemistry. Frank began in the Class of 1959, but left school for a year to work in engineering. He married Dale, his high school sweetheart, and then returned as a member of 1960.
Professionally, he followed his chemical-engineering education at Princeton, earning a master’s and Ph.D. from the University in 1964, with a succession of positions in chemical research and corporate management.
He retired as vice president for research and development of Hollingsworth and Vose, specialty-materials manufacturers, in 1998. After retirement, in addition to his other pursuits, he took up teaching, principally at the Academy of Lifelong Learning in Lewes, Del. Courses in “Art of the Mystery Novel” and “New Inventions that Have Failed” suggest the breadth and entertainment orientation of his scholarship.
Frank died Jan. 19, 2017, from complications of Alzheimer’s. He is survived by Dale, their five children, 11 grandchildren, and three great-grandsons; he had been devoted to all of them. The grandchildren still delight in his accounts of his accomplishments in the 1958 (!!) Olympics in “Javelin Catching” and “Porcupine Pole Climbing.”
