Benjamin Banneker was a free black man, astronomer, abolitionist, frequent author of almanacs, and correspondent of early American President Thomas Jefferson on the issue of slavery. He reached wide national acclaim for his almanacs published over 6 years from 1792-1797, which included his astronomical calculations alongside practical information related to medicine and literature. His almanacs were so popular that President Jefferson took it upon himself to send a copy overseas to the French Academy of Science! What would you write to the President if you had a chance?
