Chuck Noll, who built the “Steel Curtain” Pittsburgh Steelers of the 1970s into one of the most dominant teams in pro football history, becoming the only N.F.L. coach to win four Super Bowl championships, died on Friday at his home in Sewickley, Pa., outside Pittsburgh. He was 82.

His death was confirmed by his son, Chris, who said he had Alzheimer’s disease as well as heart and back problems.

When Noll was named the Steelers’ head coach in 1969, they had never reached a league championship game since their founding in 1933, and they were coming off a 2-11-1 season. Noll had played at guard and linebacker on powerful Cleveland Browns teams of the 1950s, but he had never been a head coach.

The Steelers won only one game in Noll’s first season. But he went on to coach four Super Bowl champions in a span of six seasons with a host of brilliant draft picks that helped create the memorable Steel Curtain defense and a high-powered offense.
