Dr. Hayes grew up in Havertown. He was awarded a scholarship to St. Joseph's Preparatory School, from which he graduated in 1946. Three years later, he earned a bachelor's degree from St. Joseph's University. While in college, he served in the Navy Reserve as a pharmacy technician and sailed to Nova Scotia aboard the aircraft carrier Midway.
He earned a master's degree in microbiology from the University of Pennsylvania and attended Penn's Wharton School before being drafted into the Army. From 1954 to 1956, he was a biological sciences assistant at Fort Detrick, Md.
After his discharge, he worked briefly for his father's real estate business in Havertown until enrolling in medical school.
Since 1971, he was married to Felicia Gilhool Hayes, to whom he was introduced by her brother, William, a physician.
Dr. Hayes and his wife traveled in Europe, Canada, and the United States and spent time with their family at the Jersey Shore. He was a talented photographer and sketch artist and a boat, train, and car enthusiast. He loved driving twisting back roads in a zippy little car and before his death owned a Mini Cooper, his daughter, Felicia, said.
In addition to his wife and daughter, Dr. Hayes is survived by sons James and John.
