Benjamin Banneker

Benjamin Banneker (November 9, 1731 – October 19, 1806) was an American naturalist, mathematician, astronomer and almanac author. A landowner, he also worked as a surveyor and farmer. Born in Baltimore County, Maryland, to a free African-American mother and a father who had formerly been enslaved, Banneker had little or no formal education and was largely self-taught. He became known for assisting Major Andrew Ellicott in a survey that established the original borders of the District of Columbia, the federal capital district of the United States. Banneker's knowledge of astronomy helped him author a commercially successful series of almanacs. He corresponded with Thomas Jefferson on the topics of slavery and racial equality. Abolitionists and advocates of racial equality promoted and praised Banneker's works. Although a fire on the day of Banneker's funeral destroyed many of his papers and belongings, one of his journals and several of his remaining artifacts survived. Banneker became a folk-hero after his death, leading to many accounts of his life being exaggerated or embellished. The names of parks, schools and streets commemorate him and his works, as do other tributes.
