John Tyler (March 29, 1790 – January 18, 1862) was the tenth president of the United States from 1841 to 1845 after briefly serving as the tenth vice president in 1841; he was elected vice president on the 1840 Whig ticket with President William Henry Harrison. Tyler signed into law some of the Whig-controlled Congress's bills, but he was a strict constructionist and vetoed the party's bills to create a national bank and raise the tariff rates. He believed that the president should set policy rather than Congress, and he sought to bypass the Whig establishment, most notably senator Henry Clay of Kentucky. Tyler was of frail health, thin and prone to diarrhea throughout life. At the age of twelve, he entered the preparatory branch of the elite College of William and Mary, continuing the Tyler family's tradition of attending the college. Tyler graduated from the school's collegiate branch in 1807, at age seventeen.
