John Quincy Adams (/ˈkwɪnzi/ (listen); July 11, 1767 – February 23, 1848) was an American statesman, diplomat, lawyer, and diarist who served as the sixth president of the United States from 1825 to 1829. He previously served as the eighth United States Secretary of State from 1817 to 1825. While a member of the Senate, Adams served as a professor of logic at Brown University and as the Boylston Professor of Rhetoric and Oratory at Harvard University. Adams's devotion to classical rhetoric shaped his response to public issues, and he would remain inspired by those rhetorical ideals long after the neo-classicalism and deferential politics of the founding generation were eclipsed by the commercial ethos and mass democracy of the Jacksonian Era. Adams's victory made him the first child of a president to serve as president himself. Stevenson, an ally of Jackson, expected that the committee chairmanship would keep Adams busy defending the tariff even while the Jacksonian majority on the committee would prevent Adams from accruing any real power.
