Step 1 : Introduction to the question "Which President appointed the most Supreme Court justices?"
...The president who appointed the most Supreme Court justices was George Washington, who named a total of 11 justices to the Court. As the nation's first president, Washington had the unique responsibility of shaping the newly established judiciary under the Constitution. He appointed all six of the original justices to the first Supreme Court in 1789, including Chief Justice John Jay. Over the course of his two terms, vacancies allowed him to nominate five more justices, giving him unparalleled influence over the foundation and direction of the early Court. No other president has appointed more justices.
