Ken Behring, the owner of the Seahawks for nearly a decade, passed away on Tuesday at the age of 91.
"We are saddened by the loss of former Seahawks owner Ken Behring," the team said in a statement. "We send our heartfelt condolences to Mr. Behring's family and friends."
Behring bought the team from the Nordstrom family in 1988, later selling the Seahawks to Paul Allen in 1997. In 1995, Behring established the Seattle Seahawks Charitable Foundation to promote the healthy, social, emotional, intellectual and physical development of youth by enhancing opportunities for participation in sports and fitness activities.
After selling the Seahawks, Behring established the Wheelchair Foundation, committing $15 million to the cause in 2000, and he traveled the world to deliver wheelchairs to disabled people on five continents.
