Beverly Sackler, a philanthropist and matriarch of the family that owns Purdue Pharma, whose painkiller OxyContin has been blamed for the opioid epidemic, died on Monday . She was 95 .

Her death was disclosed in a legal filing by Purdue Pharma’s lawyers in United States bankruptcy court, where last month state and local jurisdictions and other plaintiffs reached a settlement that would require the family to relinquish the company and pay at least $3 billion in claims. Purdue Pharma filed for bankruptcy; suits from 25 states are pending.

Last week a judge in bankruptcy court in White Plains, N.Y., citing the mounting legal costs, ordered a pause in those states’ action and urged the parties to work toward a compromise.

Ms. Sackler had been a board member of Purdue Pharma since 1993.

The court filing did not say where she died, give the cause of death or list her survivors. She lived in Greenwich, Conn.
