Who was the first Chief Justice of the United States?

The first Chief Justice of the United States was John Jay. Appointed by George Washington in 1789, Jay played a crucial role in establishing the Supreme Court's authority and functions during the formative years of the United States. His leadership helped shape the early judiciary and set precedents in American law. Jay served until 1795, and his tenure was characterized by an emphasis on the rule of law and the administration of justice.

Other figures mentioned, such as John Marshall, later served as Chief Justice and significantly impacted the power of the Supreme Court, but they did so after Jay's term. John Roberts and Roger Taney also held the position at later times in U.S. history, but Jay's role as the first Chief Justice laid the groundwork for the judicial system in the young nation.
