Mr. Kornblau tried civil-litigation cases in state and federal courts throughout Pennsylvania and New Jersey. His goal was to provide counsel and compassion, his family said.
Unofficially, Mr. Kornblau used his skills to help friends and neighbors who might be having a personal problem or need an introduction or favor.
"All you had to do was mention a problem you were having," his wife said. "He was on the phone working his magic."
Born in the Flushing section of New York City, he attended Francis Lewis High School and graduated magna cum laude from Boston University in 1979, where he obtained bachelor of science degrees in political science and history.
After graduation, he worked for the Democratic Congressional Campaign Committee in Washington.
He earned a law degree at Temple University School of Law, where he met his wife. The two graduated from Temple in 1982, and decided to settle in the area. At various times, they lived in Neshaminy Valley and Huntingdon Valley.
In 2010, Mr. Kornblau and his son Jonathon established Golden Corral franchise restaurants in Bensalem and Audubon, Camden County.
"He loved it," his wife said. Mr. Kornblau especially enjoyed treating veterans to a free meal and a personal welcome on Veterans Day.
"He would greet each one and thank them for their service to our country," his wife said. Mr. Kornblau died on the day he would have carried out his annual ritual.
In addition to his wife and sons, he is survived by his mother, Roslyn, and two brothers.
