Benjamin Banneker Challenges Jefferson on Slavery
Benjamin Banneker sent a now-famous letter to Secretary of State Thomas Jefferson challenging the hypocrisy of a slaveholder writing about human liberty, enclosing a manuscript copy of his almanac as proof of Black intellectual capability. Jefferson's reply acknowledged Banneker's abilities, and the exchange was widely published as a landmark moment in early American anti-slavery thought.
