His family is grieving the loss of Snider's first wife, Myrna Snider Thomas, who passed away on May 22 after a battle with lung cancer. Myrna Snider Thomas, 78, was the mother of four of Snider's children: Craig, Jay, Lindy and Tina.
Snider brought professional hockey back to Philadelphia when he founded the Flyers in 1966 with the help of Bill Putnam and Jerry Wolman. The Flyers won back-to-back Stanley Cups in 1974 and '75 and Snider was inducted into the Hockey Hall of Fame in 1988.
During a May 7 news conference to introduce Ron Hextall as the Flyers' sixth general manager, Snider seemed as fired up as ever that his team's quest for a third Stanley Cup fell short in the first round. Snider neither revealed nor even hinted at the brutal disease he was battling concurrently.
"It's very frustrating. Everybody wants to win the Cup," Snider said recently. "We've been to the Stanley Cup final eight times since 1973-74, which is the most of any team in that same time. We've reached the conference finals 15 times since that time, which is the most of any NHL team in that time frame. And since 1973-74, the Flyers rank first among all NHL teams in both wins and points.
"So, while we didn't win the other six times in the Stanley Cup final . . . I think that's a pretty damn good record and one that I'm very proud of."
Since their first season in 1967-68, the Flyers are 1,821-1,254-457-104 all-time.
In 1999, Snider was selected by a Daily News poll as Philadelphia's greatest sports mover and shaker. He is also a member of the Philadelphia Sports Hall of Fame, the United States Hockey Hall of Fame and the Philadelphia Jewish Sports Hall of Fame.
Snider, a one-time owner of the Eagles and 76ers, sold a 63 percent stake in Comcast-Spectacor in 1996. He retains the managing stake in Comcast-Spectacor, which includes the Flyers, international arena management company Global Spectrum, plus numerous food service, marketing, ticketing and ice rink ventures.
Comcast Cable, the majority owner of Comcast-Spectacor, has recently asserted more sway in the operating of Snider's empire with the hiring of president Dave Scott. It is Scott, the Comcast-Spectacor president, who replaced chief operating officer Peter Luukko after Luukko abruptly resigned last December.
Snider, an avid tennis player and workout fanatic, has made it abundantly clear that he is still hands-on with the day-to-day operations of Comcast-Spectacor.
Snider married Lin Spivak, 47, on Valentine's Day in 2013. He splits his time throughout the year between his suburban Philadelphia home and his residence in Montecito, Calif. Snider has six children and 15 grandchildren.
The Flyers' parent company said it would not have any further comment on his condition.
