Banneker was a free African American who was largely self-educated in astronomy and mathematics. In 1761, he drew attention by building a wooden clock that kept precise time for some 50 years. He accurately predicted a solar eclipse in 1789 and began publishing annually the Pennsylvania, Delaware, Maryland, and Virginia Almanac and Ephemeris, sending an early copy to Thomas Jefferson to counter the belief that African Americans were intellectually inferior. How did Jefferson respond? Discuss
