The last week is dedicated to science.
Benjamin Banneker was a self-educated astronomer, mathematician, and farmer. He was among a few hundred free African-Americans living in Maryland, where slavery was legal at the time. Banneker is perhaps best known for a series of almanacs he published between 1792 and 1797 that contained detailed astronomical calculations of his, as well as writings on topics of the day. Banneker also had a small role in helping to survey Washington D.C. in 1791 (this information comes from thoughtco.com)
