The only person to hold both of these positions was William Howard Taft, who was elected the 27th President of the United States (1909–1913) and then the tenth Chief Justice of the United States (1921–1930).
He established a postal savings system, established the Interstate Commerce Commission, approved the first tariff reform since 1897, and brought over 75 antitrust cases to court, far more than "trust-buster" Theodore Roosevelt did.
As president, Taft did not advance civil rights in any other way than by publicly endorsing George Washington's theory of racial relations and the advancement of African Americans.
His initiatives focused on advancing democracy, economic changes and social welfare.
