Mr. Ginensky was a staff sergeant in the Army and was stationed on Iwo Jima after U.S. forces took control of the Pacific island in 1945.
After the war, the New York native did repair work on Cadillacs and later owned a Brooklyn deli. He liked to innovate with food. He invented the "knizza."
"It's not a pizza. It's not a knish. It's a knizza," his daughter said. And it was tasty.
He sold the deli in the 1970s and went on to manage apartments in New York.
About seven years ago, he and his wife, whose health was declining, moved to Philadelphia to be close to their children. The transplanted New Yorker became a big fan of the Phillies and 76ers.
In his later years, he became an advocate for the health-enhancing properties of vinegar and dark chocolate. "His pastime was giving everybody advice," his daughter recalled, describing how he passed out photocopied brochures on the benefits of vinegar.
Mr. Ginensky also took up painting late in life. "At Watermark, he started a painting class for people who were really sick," his daughter said.
After his wife died, Mr. Ginensky spent his time "watching Westerns," and his health deteriorated, his daughter said. But toward the end, he was at peace, she said.
In addition to his daughter, Mr. Ginensky is survived by a son, Steven; three grandchildren; and a sister.
The funeral will be at 1 p.m. Sunday, June 30, at Beth David Reform Congregation, 1130 Vaughan Lane, Gladwyne. Burial will be in Haym Salomon Memorial Park. Shivah will be at his daughter's home Sunday and Monday, and at his son's home on Tuesday.
