Maryland, 1731
The Man of
The Stars
Benjamin Banneker was a freed person of color who mastered the universe from a small farm in Baltimore. He was a scientist before America was even a nation.
The Free Farmer
Born to freed slaves, Banneker grew up on a 100-acre tobacco farm. While most Black people in America were enslaved, Banneker’s family owned their land, which gave him a rare gift: the time to think.
He attended a small Quaker school for a short time, but for the most part, he was entirely self-taught, reading every book he could get his hands on.
Precision from Wood

Using only a pocket watch as a guide, Banneker hand-carved every single gear from wood. It kept perfect time for 40 years.

Observer of the Earth
Banneker was more than an astronomer; he was an expert naturalist. He was the first to document the cycle of the **17-year locust** (Magicicada).
Bee Keeper
He studied the behavior of bees and implemented early versions of sustainable irrigation on his farm.
Locust Cycle
He recorded three distinct appearances of the 17-year cicadas, predicting their next return with scientific accuracy.
Defining the Federal City
In 1791, Banneker joined the team tasked with surveying the new Washington D.C. He lived in a tent on the site for months.
The Work
- Set the starting point at Jones Point, Virginia.
- Used his zenith sector to align the boundaries by the stars.
- Maintained the complex astronomical clocks for the team.
Calculating the Heavens
His greatest intellectual labor was his **Pennsylvania, Delaware, Maryland, and Virginia Almanac**.

Letter to Thomas Jefferson
Banneker sent Jefferson his first Almanac to prove that Black people possessed equal intellectual power. He wrote:
"Sir, suffer me to recall to your mind that time, in which the arms and tyranny of the British Crown were exerted... that you should at the same time be found guilty of that most criminal act, which you professedly detested in others."
A Reluctant Admission
Jefferson, who wrote the Declaration of Independence but owned hundreds of enslaved people, was forced to reply.
Jefferson's Reply
"No body wishes more than I do to see such proofs as you exhibit, that nature has given to our black brethren, talents equal to those of the other colors of men..."
Later Doubt
Despite Banneker's brilliance, Jefferson later wrote to friends doubting Banneker had done the math himself, showing how deep prejudice ran.
A Voice for Freedom
Banneker didn't stop at one letter. He published his correspondence with Jefferson in his Almanacs to ensure the public saw the debate.
He is considered one of America's first civil rights leaders.
The Fire in 1806
Banneker died at the age of 74. On the day of his funeral, while the mourners were at the graveyard, his house mysteriously burst into flames.
Many believe the fire was set to silence his evidence and research forever.
Legacy Among
the Stars
Benjamin Banneker proved that the human mind is universal. He measured the earth, predicted the heavens, and challenged a nation to live up to its own words of equality.
