William Harrison – 9th President of the United States
William Henry Harrison (February 9, 1773 – April 4, 1841) was an American military leader, politician, the ninth President of the United States, and the first president to die in office. The oldest president elected until Ronald Reagan in 1980, Harrison served 32 days in office, still the shortest tenure in United States presidential history, before his death in April 1841. His death created a brief constitutional crisis, but ultimately resolved many questions about presidential succession left unanswered by the Constitution until passage of the 25th Amendment.
