Benjamin Banneker was a man of many parts. He was an African American scientist, astronomer, surveyor, compiler of almanacs, farmer, and a self-educated mathematician. He was a strong advocate of racial equality and called for ending the slavery. Bannekar was born in Maryland in early eighteenth century and was an active author of almanacs who exchanged his letters with the famous Thomas Jefferson. In these letters Benjamin exhorted Jefferson to do his best for ensuring racial equality and abolition of slavery. Incidentally Bannekar was a free black man who was an owner of a farm located at close proximity to Baltimore. Benjamin Banneker is mostly known for being a member of a group that was led by Major Andrew Ellicott. This group did extensive survey work across the borders of the District of Columbia that was the United States’ federal capital district. Several advocates who were in favor of racial equality and abolitionists praised and promoted Banneker’s works extensively. A fire broke out on the day of Banneker’s funeral that destroyed many of his personal belongings and papers except Banneker’s astronomical journal.
