Herein shall we continue the story of Benjamin Banneker, surveyor, farmer, astronomer, polymath, and noted abolitionist. Be sure to read Part One, the history of Banneker’s family and his acquisition of mathematical knowledge.
Benjamin Banneker was nearly sixty when he hit upon the idea of publishing an almanac of natural information.
