Joan Ruth Bader Ginsburg (March 15, 1933 – September 18, 2020) was an American lawyer and jurist who served as an associate justice of the Supreme Court of the United States from 1993 until her death in 2020. She was nominated by President Bill Clinton to replace retiring justice Byron White, and at the time was generally viewed as a moderate consensus-builder. She eventually became part of the liberal wing of the Court as the Court shifted to the right over time. Ginsburg was the first Jewish woman and the second woman to serve on the Court, after Sandra Day O'Connor.
