Who was the first female Supreme Court Justice in the United States?

The first female Supreme Court Justice in the United States was Sandra Day O'Connor. Appointed by President Ronald Reagan, she took her seat on the court in 1981. O'Connor's appointment was a significant milestone not only for women in law but also for the representation of women in government positions, marking a shift towards greater inclusivity in a historically male-dominated institution.

Her impact extends beyond her role as a trailblazer; O'Connor played a crucial role in many pivotal decisions during her time on the court, often serving as a swing vote in cases that would define the legal landscape on issues such as reproductive rights, affirmative action, and the balance of powers. Her legacy continues to inspire future generations of attorneys, judges, and public servants.
