The Kilimanjaro trek involved eight hikers, seven from South Jersey, organized by Steven Reiner, a former South Jersey podiatrist.
Reiner, who now lives in Port Townsend, Wash., said in a phone call from a ski lodge in British Columbia that he shared hours sweating with Mr. Noyovitz at a Maple Shade gym and, later, on ski slopes in Colorado.
On Kilimanjaro, Reiner said, Mr. Noyovitz "did amazingly well."
To compensate for his age, "one of the guides would leave earlier in the morning with him," before the others set out.
Fatigue stopped him short of completing the trek with Reiner and three others, but, Reiner said, Mr. Noyovitz was no less enthusiastic about what he had done.
"The man loved the challenge."
Mr. Noyovitz was a late convert to fitness.
"He quit smoking, cold turkey, at 45," his daughter said. "He gained a bunch of weight."
So he started skiing with Orlin and her husband, Alan. "In his 50s, he started to go to the gym."
After he retired in his mid-60s, she said, "he was spending three, four hours in the gym, four times a week."
And, she said, "he used to be a jogger. Five miles, six miles, into his 70s. Three, four times a week."
Mr. Noyovitz grew up near 40th Street and Girard Avenue in West Philadelphia, graduated from Overbrook High School, and flew 25 World War II combat missions as a radio operator and waist gunner on B-25 bombers based in the Philippines.
He returned to earn a bachelor's in accounting at Temple University on the GI Bill. He began his 40-year career, as an accountant with Radio Corporation of America, in 1959. Over the years he worked at several South Jersey locations and, while the family lived in Levittown, commuted to GE headquarters in Manhattan.
Besides his daughter, Mr. Noyovitz is survived by sons Paul and Philip, daughter Judi Hart, eight grandchildren, and a great-granddaughter. His wife, Evelyn, died in 1993.
A graveside service was set for 1:30 p.m. Sunday, April 6, at Roosevelt Memorial Park, 2701 Old Lincoln Highway, Trevose.
