In 1938 Harold E. Stassen was elected governor of Minnesota at age 31, an office he resigned in 1943 to enter the United States Navy at the height of World War II. In the postwar years he helped write the charter of the United Nations and, serving in the Eisenhower administration, very nearly achieved a nuclear test ban treaty with the Soviet Union. He is famously known as a perennial candidate for the Republican Party nomination for president, seeking it 10 times between 1944 and 1992.
