Throughout his life Banneker was troubled that all blacks were not free. And so, in 1791, he wrote to Secretary of State Thomas Jefferson, who had signed the Declaration of Independence. Banneker attacked the institution of slavery and dared to call Jefferson a hypocrite for owning slaves. Jefferson responded. This is the story of Benjamin Banneker--his science, his politics, his morals, and his extraordinary correspondence with Thomas Jefferson. Illustrated in full-page scratchboard and oil paintings by Caldecott Honor artist Brian Pinkney.
