President William Harrison Biography
William Henry Harrison Sr. was an American military officer, politician, and the ninth President of the United States. He died of pneumonia thirty-one days into his term, thereby serving the shortest tenure in United States presidential history. Because he was the first president to die in office, his death sparked a constitutional crisis and questions and debates about succession.
