1731 - 1806
Born Benjamin Banneky in Elkridge Landing, Maryland, Banneker's mother was half African, half British, and his father was an emancipated slave. Early on Banneker took an interest in astronomy. His scientific interests led him to build what is said to be the first clock in America in 1753. In 1772 Banneker was hired by a neighboring family, the Ellicotts, to assist with the construction of a mill. He established a relationship with the family, who provided him with astronomical tools and texts, allowing him to pursue his interests and begin work on an almanac.
The Ellicotts' son Andrew shared Banneker’s scientific mindset. A successful geographer, Ellicott was retained as a surveyor by Thomas Jefferson to work with Pierre Charles L’Enfant on the creation of a plan for the new capitol city, Washington, D.C. Ellicott asked Banneker to work with him on the project. In 1792 the two men were placed in charge of the design after L’Enfant’s controversial dismissal and departure with the plans in tow. It is rumored that Banneker redrew L’Enfant’s plans from memory. Banneker and Ellicott’s modified version of L’Enfant’s plan is known as the Ellicott plan.
In 1791, during his work in Washington, Banneker published Banneker’s Almanac. After concluding work on the Capitol, he wrote and published the almanacs annually. Following his death,Banneker’s work was used by the abolitionist movement as proof of the accomplishments and intellect of the African American.
