Big Idea

Banneker offered his own scientific work as evidence against claims of Black intellectual inferiority, and his letter to Jefferson confronted the new nation with the gap between its founding ideals and slavery.

Before Class

Students read the profile of Benjamin Banneker, including the Key Dates and Sources.

Discussion Questions

  1. Why did Banneker send Jefferson a manuscript of his almanac calculations along with his letter? How did the almanac serve as part of his argument?
  2. Banneker turned the language of the Declaration of Independence back on its author. Why is that such a powerful strategy?
  3. Read Jefferson’s reply. Did he answer Banneker’s challenge? What did he say, and what did he leave unsaid?
  4. Banneker taught himself mathematics and astronomy from borrowed books and instruments. What does his story suggest about access to knowledge in the eighteenth century?

Activity

Pairs read excerpts from Banneker’s letter of 19 August 1791 and Jefferson’s reply of 30 August. On a two-column chart they record each writer’s main claims and the evidence offered for them. Pairs then decide whether Jefferson’s reply meets Banneker’s challenge and draft a short response Banneker might have written back. Close by discussing why this exchange still matters in arguments about equality.
