(AP) — Longtime Pittsburgh Steelers chairman and former U.S. ambassador to Ireland Dan Rooney has died at age 84.

The Pro Football Hall of Famer took over operation of the Steelers from his father in the 1960s and turned it into a team that had four Super Bowl-winning seasons in the 1970s.

He also conceived the NFL's "Rooney Rule" that gave minorities a better opportunity to be hired for coaching and front office positions.

Funeral arrangements set for Steelers' chairman Dan Rooney

PITTSBURGH (AP) — The funeral arrangements are set for Pittsburgh Steelers Chairman Dan Rooney, and they include a public viewing at Heinz Field.

Team spokesman Burt Lauten says that will be held from 2 p.m. to 7 p.m. Monday at the PNC Champions Club at the stadium.

Rooney's funeral Mass will be Tuesday at 11 a.m. at St. Paul Cathedral in the city's Oakland section.

Gov. Tom Wolf on Friday ordered the Commonwealth flag to be flown at half-staff across Pennsylvania to honor Rooney, who died Thursday at 84.

The family is asking that memorial contributions be made to Rooney's alma mater, Duquesne University, or the United Way of Southwestern Pennsylvania.

Rooney is survived by his wife, Patricia, and seven of the couple's nine children.
