Banneker published Almanacs until He dedicated them to the cause of equality and peace and the Almanac contains the correspondence between Banneker and Jefferson. In [ 1 ] Bedini claims that this Almanac was When he became too old to work on the farm, Banneker sold it to the Ellicot family on condition that he was allowed to live in the farm house for the rest of his days. He spent his last days alone in the farmhouse studying and continuing to carry out scientific experiments.
On the day of Banneker's funeral the farm house burnt to the ground and his laboratory and the clock he made in his younger days was all destroyed. Only one manuscript journal which Banneker had written was not in the house and so survived.
Every other record of his achievements, except the published Almanacs, were lost in this probably deliberate fire. The surviving manuscript journal contains mathematical puzzles and their solutions. To give just one example:- Divide 60 into four such parts that the first being increased by 4 , the second decreased by 4 , the third multiplied by 4 , the fourth part divided by 4 , that the sum, the difference, the product and the quotient shall be one and the same number.

Mary Bannaky grew up, purchased a slave, Robert, whom she later married and lived on the family farm. On Nov. Using the Bible, Molly Bannaky taught Mary's children to read, and soon after, Benjamin would read the bible to his mother and grandmother.
For those times, life was good to this little community, but work was hard, but not challenging to Benjamin. He learned to play the flute and the violin, and when a Quaker school opened in the valley, Benjamin attended it during the winter where he learned to write and elementary arithmetic. He had an eighth-grade education by time he was 15, at which time he took over the operations for the family farm. He devised an irrigation system of ditches and little dams to control the water from the springs known around as Bannaky Springs on the family farm.
Their tobacco farm flourished even in times of drought. Banneker became fascinated with the patent watch of a friend, Josef Levi.
Levi gave Benjamin the watch and he took it apart to 'study its workings. Due to its precision it struck every hour, on the hour, and continued to do so nearly forty years the clock brought fame to young Banneker. Thus he began a watch and clock repair business. Further, he helped another famous Marylander, the industrialist Joseph Ellicott, to build a complex clock. Banneker and the Ellicott brothers became friends. Joseph Ellicott was an amateur mathematician and astronomer and lent Banneker books on astronomy and mathematics as well as instruments for observing the stars.
Banneker taught himself astronomy and advanced mathematics and, in , he began to devote serious attention to both subjects. He successfully predicted the solar eclipse that occurred on April 14, , contradicting the forecasts of prominent mathematicians and astronomers of the day. Banneker's habits of study appear odd to the non-scientist. It is said that on many nights, he would wrap himself in a great cloak and lie under a pear tree and meditate on the revolutions of the heavenly bodies.
He would remain there throughout the night and take to his bed at dawn. As reported in the Georgetown Weekly Ledger March 12, , when Banneker was 60, he was appointed, by President George Washington, to a three man team of surveyors headed by Major Andrew Ellicott, Joseph's cousin, to survey the future District of Columbia.
Banneker, the paper said, was "an Ethiopian whose abilities as surveyor and astronomer already prove that Mr.
Banneker and Ellicott worked closely with Pierre L'Enfant, the architect in charge. However, L'Enfant could not control his temper and was fired. It was the first time in his life Banneker ventured more than ten miles from his farm. Letters from Ellicott show that in February , he set out with Banneker and several field laborers for Jones Point, Virginia, to plot the boundary lines of the nascent Federal City.
Each day, Ellicott would use the regulator clock to set his own timepiece, which he would use to determine latitude. At night, Banneker would record astronomical observations. While Banneker is not mentioned in any of the reports from that day, he undoubtedly would have attended.
After consulting on the Federal City project, Banneker returned to his farm in April and resumed work on an almanac for farmers. The following pages contained an essay on the cosmos, a fable about domestic life, a formula for tree medicine, and words of wisdom.
Finally, the almanac takes up advocacy, publishing an excerpt from an essay by abolitionist David Rittenhouse originally printed in Columbian Magazine.
The work is either correct or it is not. In this case, I believe it to be perfect. Banneker was clearly frustrated by the attention paid to his race instead of his work. No matter how unique his talents or special his accomplishments, contemporaries and critics always reverted to a discussion of his skin color.
There was no talking about Benjamin Banneker—even in praise—without remarking on his background. He could never truly know whether his almanac was worthy of publication on its own merits or just because it served a moral cause. Though he was never enslaved, Benjamin Banneker was never free to be just Benjamin Banneker.
Perhaps it was exhaustion as much as outrage that led Banneker to mail an advance copy of the almanac to Secretary of State Jefferson on August 19, Because the almanac was still in production, Banneker handwrote the entire forty-eight-page publication again.
How pitiable is it to reflect, that altho you were so fully convinced of the benevolence of the Father of mankind, and of his equal and impartial distribution of those rights and privileges which he had conferred upon them…that you should at the Same time be found guilty of that most criminal act, which you professedly detested in others, with respect to yourselves.
He stopped short of telling Jefferson to emancipate the men, women, and children he enslaved — Jefferson owned over during his lifetime — but the message was clear. He wrote: "32043o body wishes more ardently to see a good system commenced for raising the condition both of their body and mind to what it ought to be, as fast as the imbecillity of their present existence, and other circumstances which cannot be neglected, will admit.
Dated August 30, , Secretary of State Thomas Jefferson penned this letter in response to Benjamin Banneker questioning his commitment to liberty. Jefferson—a slave owner—acknowledged the paradox and expressed his personal distaste for the institution, but did little else to directly address the issue. Not to be deterred, Banneker published his correspondence with Jefferson shortly after the appearance of the almanac for The letters reinvigorated discourse over the problem of slavery.
But Banneker did not advocate for abolition in his almanacs thereafter — possibly because it was dangerous to push the envelope further in a state that permitted slavery.
