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 graduated from the school's collegiate branch in 1807, at age seventeen. Among the books that formed his economic views was Adam Smith's The Wealth of Nations, and he acquired a lifelong love of Shakespeare. His political opinions were shaped by Bishop James Madison, the college's president and namesake of the future president; the bishop served as a second father and mentor to Tyler. Hatch, Louis C.
