Charles Henry Noll (January 5, 1932 – June 13, 2014) was an American professional football player and head coach. Regarded as one of the greatest head coaches of all time, his sole head coaching position was for the Pittsburgh Steelers of the National Football League (NFL) from 1969 to 1991. When Noll retired after 23 years, only three other head coaches in NFL history had longer tenures with one team.
After a seven-year playing career that included two NFL Championships as a member of his hometown Cleveland Browns and several years as an assistant coach with various teams, in 1969 Noll took the helm of the Steelers (which had played in only one playoff game in its previous 36 years, a 21–0 loss), and turned it into a perennial contender. As a head coach, Noll won four Super Bowls, four AFC titles and nine Central Division championships, compiled a 209–156–1 (.572) overall record, a 16–8 playoff record and had winning records in 15 of his final 20 seasons. His tenure was defined by a dominant Steelers team, built on the legendary "Steel Curtain" defense and a potent offense.
