John Tyler (1790-1862) served as America’s 10th president from 1841 to 1845. He assumed office after the death of President William Henry Harrison (1773-1841), who passed away from pneumonia after just a month in the White House. Nicknamed “His Accidency,” Tyler was the first vice president to become chief executive due to the death of his predecessor.
