From NPR:

Justice Ruth Bader Ginsburg, the demure firebrand who in her 80s became a legal, cultural and feminist icon, died Friday. The Supreme Court announced her death, saying the cause was complications from metastatic cancer of the pancreas.

The court, in a statement, said Ginsburg died at her home in Washington, D.C., surrounded by family. She was 87.

“Our nation has lost a justice of historic stature,” Chief Justice John Roberts said. “We at the Supreme Court have lost a cherished colleague. Today we mourn but with confidence that future generations will remember Ruth Bader Ginsburg as we knew her, a tireless and resolute champion of justice.”
