The New York Giants announced on Tuesday that John Rooney, the brother of the late chairman Daniel M. Rooney and the child of Arthur J. Rooney, the man who created the Pittsburgh Steelers, had passed away.

One of Art Rooney’s five children, John Rooney, was a tiny shareholder in the business. When ownership changed to Dan Rooney and his son, the current team president Art Rooney II, in 2008, he sold the majority of his initial 16% stake.

The Rooneys had to adhere to NFL regulations involving a major stakeholder holding more than 30% of the business’ shares as well as keeping John and Timothy Rooney’s gambling enterprises in Florida distinct from the football sector.

Rooney’s brother Patrick Rooney attended Mount St. Mary’s University in Emmitsburg, Maryland. While he was a member of the team, John Rooney oversaw the Steelers’ training camp at St. Vincent College.
