William Henry Harrison [SEP] Introduction
William Henry Harrison (February 9, 1773 – April 4, 1841) was an American military officer and politician who served as the ninth president of the United States in 1841. He died of either typhoid, pneumonia, or paratyphoid fever 31 days into his term, becoming the first president to die in office and the shortest-serving president in U.S. history. His death sparked a brief constitutional crisis regarding succession to the presidency, because the Constitution was unclear as to whether Vice President John Tyler should assume the office of president or merely execute the duties of the vacant office. Tyler claimed a constitutional mandate to become the new president and took the presidential oath of office, setting an important precedent for an orderly transfer of the presidency and its full powers when the previous president fails to complete the elected term.
