John Quincy Adams — 6th President (1825–1829)

**John Quincy Adams** was the most intellectually accomplished president — fluent in seven languages, a diplomat from age 14, Secretary of State under Monroe, and the architect of the Monroe Doctrine before becoming president. His single term was paralyzed by political opposition, but his post-presidency in the House of Representatives, where he fought slavery for seventeen years, proved him one of America's greatest public servants.
