- William Henry Harrison (Wikipedia)
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 from March 4 to April 4, 1841, the shortest presidency in U.S. history. He was also the first U.S. president to die in office, causing a brief constitutional crisis since presidential succession was not then fully defined in the U.S. Constitution. Harrison was the last president born as a British subject in the Thirteen Colonies and was the grandfather of Benjamin Harrison, the 23rd U.S. president.
