Meet the self-educated genius who mapped the nation's capital, predicted the stars, and boldly challenged Thomas Jefferson on racial equality.
In this episode of pplpod, we dive deep into the extraordinary life of Benjamin Banneker, a free African-American mathematician, astronomer, surveyor, and almanac author born in Maryland in 1731. Despite having little to no formal education, Banneker taught himself advanced science, built a functioning wooden clock from scratch that ran for over fifty years, and published a commercially successful series of astronomical almanacs and ephemerides in the 1790s.
We explore Banneker's major turning points, including his vital (and often debated) role assisting Major Andrew Ellicott in the 1791 survey of the original borders of the District of Columbia. We also unpack his powerful 1791 correspondence with Thomas Jefferson. Banneker bravely sent the then-Secretary of State a manuscript of his almanac as proof of Black intellectual equality, using the language of the Declaration of Independence to call out the hypocrisy of slavery and demand justice for African Americans.
Finally, we separate the man from the mythology that has grown around his legacy over the last two centuries. From his fascinating journals on the 17-year cicada cycle to his influence on early American history and the abolitionist movement, discover why this 18th-century pioneer’s story still matters today.
