Franklin Delano Roosevelt (/ˈroʊzəvəlt/, /-vɛlt/; January 30, 1882 – April 12, 1945), often referred to by his initials FDR, was an American politician who served as the 32nd president of the United States from 1933 until his death in 1945. Roosevelt became very ill with influenza and a complicating pneumonia, but he recovered by the time the ship landed in New York. After Germany signed an armistice in November 1918, surrendering and ending the fighting, Daniels and Roosevelt supervised the demobilization of the Navy. Against the advice of older officers such as Admiral William Benson—who claimed he could not 'conceive of any use the fleet will ever have for aviation'—Roosevelt personally ordered the preservation of the Navy's Aviation Division. With the Wilson administration coming to an end, Roosevelt began planning for his next run for office. Roosevelt and his associates approached Herbert Hoover about running for the 1920 Democratic presidential nomination, with Roosevelt as his running mate.
