Theodore Roosevelt—McKinley’s second vice president—won the Nobel Peace Prize in 1906 when, as president, he negotiated an end to the Russo-Japanese War. Elihu Root—McKinley’s second secretary of war—also won the Nobel Peace Prize in 1912 for his efforts in attempting to bring different countries together for arbitration purposes. Root replaced Russell A. Alger as secretary of war after McKinley asked for Alger’s resignation. Root later served as secretary of state under Theodore Roosevelt. Root lived to be more than ninety years of age.
