In 1966, she married Lewis Katz, whom Mrs. Katz had met at a party when she was 16 and he was 17.
She began taking courses at the New School in New York when she moved there after college, and continued studying subjects she found interesting until she fell ill in July.
"She had no aim of a degree," Lewis Katz said. "She took classes purely to be as stimulated as possible educationally."
Mrs. Katz was hooked on the political commentary of Chris Matthews, and was an avid reader and a keen observer of world events, said her lifelong friend Phyllis Sherman.
"She was smart academically, and she was smart about people," Sherman said.
Mrs. Katz was a French teacher for a short time and later owned the Cat's Meow, a gift shop in Cherry Hill. She also had homes in New York and Florida.
When Mrs. Katz was in college, her father fell on hard times, and she began selling her clothes to earn pocket money. But she remained cheerful, adventurous, and fun-loving, said Sherman, who met her in college.
After Mrs. Katz became wealthy - her husband built a lucrative career in parking, banking, billboards, and real estate - "she never changed, not one second," her husband said.
She treated everyone equally, whether dignitary or elevator operator.
"Actually, she was skeptical of the dignitary, and would treat the elevator operator or the woman behind the counter with enormous kindness and compassion," said her son, Drew Katz.
Mrs. Katz gave freely to causes she cared about, most often with little fanfare.
Once, she met a 3-year-old in a nail salon. She was charmed by the boy, and moved him and his mother into a house she bought for them. She became another mother to the child, helping to raise him while his mother worked - attending PTA meetings, sending him to college.
"She saw him as one of her children," Lewis Katz said.
Her life was full of such stories. She adopted a church in Camden, providing scholarships to children there. She moved one of the church members she particularly connected with to an apartment in Pennsauken, and paid her rent for 20 years.
When her children were young, Mrs. Katz took them to play with physically and mentally disabled children. A group home in South Jersey will soon be named for her.
"She gave on a one-to-one basis," Drew Katz said. "She got her hands dirty. She didn't give to charities that she had no connection to. She worked to make a difference in the lives of people who touched her."
But family was always Mrs. Katz's first priority. She was the adored "Nana" to four grandchildren. When they were away at camp, a day rarely passed without her sending them a package.
"She was relentless in her love and connection to her family," Drew Katz said.
Survivors include her husband, son, and daughter; grandchildren; and her father, Irwin Hyman.
