William Henry Harrison was the ninth President of the United States, serving for a brief period in 1841. A member of the Whig Party, he was born on February 9, 1773, in Virginia and later moved to Ohio. Harrison is best known for his military leadership during the War of 1812, particularly at the Battle of Tippecanoe, which earned him national fame. His presidency was notably short, lasting only 31 days before he died on April 4, 1841, making him the first U.S. president to die in office.
