Chuck Noll, the Hall of Fame coach who led the Steelers to four Super Bowls in the 1970s, died Friday at the age of 82, according to numerous reports out of Pittsburgh, the Associated Press and CNN.
According to the Pittsburgh Tribune Review, Noll's wife, Marianne, found him unresponsive at 9:45 p.m. ET. She called 911, and paramedics pronounced him dead at 9:55 p.m.
Noll had stayed out of the public eye in recent years, because, as CNN writes, he had suffered from Alzheimer's and heart problems.
In 1969, he took over a Steelers squad that had produced only two winning seasons in the previous nine years, and Pittsburgh promptly went 1-13 in Noll's first season. But by 1972, Noll (along with quarterback Terry Bradshaw, a 22-year-old running back named Franco Harris and one of the NFL's best defenses) led Pittsburgh to an 11-3 record and the franchise's first playoff appearance in 25 years.
From 1972-79, the Noll led the Steelers to an 88-27-1 regular-season record without ever missing the playoffs and while winning Super Bowls IX, X, XIII and XIV. Overall, he sported a 209-156-1 record, and he was elected to the Hall of Fame in 1993.
