About William Henry Harrison

William Henry Harrison (February 9, 1773 April 4, 1841) was the ninth President of the United States (1841), an American military officer and politician, and the first president to die in office. He was 68 years, 23 days old when inaugurated, the oldest president to take office until Ronald Reagan in 1981, and last President to be born before the United States Declaration of Independence. Harrison died on his 32nd day in office of complications from pneumonia, serving the shortest tenure in United States presidential history. His death sparked a brief constitutional crisis, but that crisis ultimately resolved many questions about presidential succession left unanswered by the Constitution until passage of the 25th Amendment. Before election as president, Harrison served as the first territorial congressional delegate from the Northwest Territory, governor of the Indiana Territory and later as a U.S. representative and senator from Ohio.
