There have been only three women to serve as U.S. Supreme Court justices in the history of the Court: Justice Sandra Day O’Connor, Ruth Bader Ginsburg, and Sonia Sotomayor. President Ronald Reagan nominated O’Connor in 1981 in part to fulfill a campaign promise to nominate the first woman on the Court. President Bill Clinton nominated Ruth Bader Ginsburg in 1993 and she still serves on the Court at the time of this writing. President Barack Obama nominated Sotomayor to the Court in 2009 to replace the retiring David Souter.
