Kyösti Kallio

Kyösti Kallio was a Finnish politician who served as the president of Finland from 1937 to 1940. His presidency included leading the country through the Winter War; while he relinquished the post of commander-in-chief to Carl Gustaf Emil Mannerheim, he played a role as a spiritual leader. After the war, he became both the first president of Finland to resign and the only one to die in office, dying of a heart attack while returning home after submitting his resignation.
