John Tyler, Jr. (March 29, 1790 - January 18, 1862) was the tenth (1841-1845) President of the United States. A long-time Democrat-Republican, he was elected Vice President on the Whig ticket and on becoming president in 1841, broke with that party. His term as Vice President began on March 4, 1841 and one month later, on April 4, incumbent President William Henry Harrison died of what is today believed to have been viral pneumonia. Wikipedia
