Who was the first female Supreme Court Justice?

Sandra Day O'Connor was the first female Supreme Court Justice, appointed by President Ronald Reagan in 1981. Her appointment marked a significant milestone in the history of the United States, as she broke the gender barrier in the highest court, paving the way for future women in law and leadership positions.

O'Connor served on the Supreme Court until her retirement in 2006. She was known for her pragmatic approach to many issues, often acting as a swing vote in critical decisions. Her influence and legacy have had a lasting impact on the Court and women's representation in the judiciary.

The other justices mentioned, Ruth Bader Ginsburg, Sonia Sotomayor, and Elena Kagan, are significant figures in the Supreme Court, but they came after O'Connor. Ginsburg, for example, was appointed in 1993, Sotomayor in 2009, and Kagan in 2010, making O'Connor the pioneering figure among them as the first female justice.
