During his twelve years in office, President Franklin D. Roosevelt appointed eight new members of the Supreme Court of the United States: Associate Justices Hugo Black, Stanley F. Reed, Felix Frankfurter, William O. Douglas, Frank Murphy, James F. Byrnes, Robert H. Jackson, and Wiley Blount Rutledge. Additionally, he elevated sitting Justice Harlan F. Stone to chief justice. Roosevelt's nine nominations filled eight seats on the Supreme Court because Byrnes resigned while Roosevelt was still in office. Roosevelt nominated Rutledge to the seat vacated by Byrnes.
