During his residency at Massachusetts General Hospital, he was an American Cancer Society Clinical Fellow from 1969 to 1971 and chief resident in pathology in 1970.
To fulfill his military obligation, he was a surgeon and chief of pathology at the Public Health Service hospital in Norfolk, Va., in 1972 and 1973 and surgeon and assistant pathology chief at the PHS unit in Baltimore in 1973 and 1974.
Dr. Schantz began his South Jersey career at what is now Virtua Voorhees hospital in 1974 as an associate pathologist and "at various times he was acting chairman of the department of pathology," his wife, Dr. Ilene S. Cottler, said.
In 1994, he became medical director of the department of pathology there, she said, and from 1995 to 1998 he was pathology department chairman for the Virtua health system.
"While there, he designed and implemented the photomicrography system for the department," which, she said, is the technique for photographing through microscopes.
From 1999 to 2004, he was medical director of the pathology laboratory at Virtua Camden.
In 2004, he left Virtua and until 2011 was a senior staff pathologist for Quest Diagnostics in Horsham, Montgomery County.
Two of his papers published by the medical journal Cancer "are considered classics, about the parathyroid," his wife said. He wrote one in 1973 and cowrote the other in 1976.
"Most recently," she said, "he enjoyed hydroponic gardening."
Besides his wife, Dr. Schantz is survived by a sister, Carole Sander, and several nieces and nephews.
