(born Nov. 9, 1731, Ellicott's Mills, Md.—died Oct. 25, 1806, Baltimore, Md., U.S.) mathematician, astronomer, compiler of almanacs, inventor, and writer, one of the first important black American intellectuals.
A free black who owned a farm near Baltimore, Banneker was largely self-educated in astronomy by watching the stars and in mathematics by reading borrowed textbooks.
