Benjamin Banneker was a prominent African American mathematician, astronomer, surveyor, and author who lived in the 18th century. Born on November 9, 1731, in Maryland, Banneker was largely self-taught and became known for his exceptional intellect and contributions to science and mathematics.

One of Banneker's most notable accomplishments was his work on predicting solar and lunar eclipses, which earned him recognition among leading scientists of his time. He also played a key role in surveying and designing the layout for the city of Washington, D.C., alongside Pierre Charles L'Enfant.

Banneker was a vocal advocate for the abolition of slavery and racial equality. In 1791, he famously wrote a letter to Thomas Jefferson, then Secretary of State, challenging the contradictions between the ideals of liberty and equality in the Declaration of Independence and the institution of slavery.

Benjamin Banneker's legacy as a pioneering African American mathematician and scientist has been celebrated throughout history, and he remains an important figure in Black history for his achievements and contributions to the fields of science and social justice.
