About two years ago, Mr. Zeidel moved in with George and Joan Bradley in their Mayfair home. Joan Bradley had befriended him when he used to live with a neighbor.
"He was like a giant teddy bear," she said. "I loved him like a second father."
Nicknamed "The Rock," Mr. Zeidel also played for Detroit and Chicago. He won a Stanley Cup ring with Gordie Howe and the Red Wings in 1952.
Playing for the Flyers in 1968, Mr. Zeidel and Boston's Eddie Shack were in a stick-swinging battle at Maple Leaf Gardens in Toronto. The Flyers were playing a home game there because part of the roof had blown off at the Spectrum.
Shack had allegedly made off-color remarks about Mr. Zeidel's being Jewish.
"He was so proud of being one of the first Jewish players in the league," Joan Bradley said.
The NHL suspended Zeidel - who had been involved in several stick-swinging incidents in his career - for four games. Shack received a three-game suspension.
After his career ended, Mr. Zeidel worked for a while as a marketing consultant for investment funds.
As for his hockey career, Mr. Zeidel once said there was a couple of reasons why he played with an edge.
"First, I played some senior hockey in Québec City, and we could play well and win, but the fans would rather have us involved in a real brawl and lose the game," he said. "There were a lot of rugged guys in the league at that time, too, so maybe it was partly a matter of survival.
"The other thing is that there's the big thing of being young and having stars in your eyes. The clubs themselves are as much or more to blame. They play up the tough guys. Guts, guts, guts is all you hear from a lot of coaches and managers, even as early as junior [league]. I was playing for some coaches and managers who would tell me, 'Go get him.' So I did."
Mr. Zeidel is survived by his wife, Marie, four children and 10 grandchildren.
Services will be held Saturday, 8 a.m. to noon, at Cassizzi Funeral Home, 2915 East Thompson St., Philadelphia.
