Referring to their attitude, the publishers said in their editorial notice that "they felt gratified in the opportunity of presenting to the public, through their press, an accurate Ephemeris for the year 1792, calculated by a sable descendant of Africa." They flatter themselves "that a philanthropic public, in this enlightened era, will be induced to give their patronage and support to this work, not only on account of its intrinsic merit (it having met the approbation of several of the most distinguished astronomers of America, particularly the celebrated Mr. Rittenhouse), but from similar motives to those which induced the editors to give this calculation the preference, the ardent desire of _drawing modest merit from obscurity_ and controverting the long established illiberal prejudice against the blacks."[167]
Banneker had himself not lost sight of the probable effect of his work in reshaping to some extent the public estimate concerning the intellectual capacity of his race. And this was the thought that prompted him to send a manuscript copy of his first almanac to Thomas Jefferson, then Secretary of State in Washington's cabinet. In his letter to Jefferson, dated August 19, 1791, Banneker made, with characteristic modesty, a polite apology for the "liberty" he took in addressing one of such "distinguished and dignified station," and then proceeded to make a strong appeal for the exercise of a more liberal attitude towards his downtrodden race, using his own achievements as a proof that the "train of absurd and false ideas and opinions which so generally prevails with respect to the Negro should now be eradicated."[168]
Thomas Jefferson took note of the moral courage and the loyalty to race evident throughout the whole of Banneker's remarkable letter and he honored it with the most courteous reply, under date of August 30, 1791. After thanking Banneker for the letter and the almanac accompanying it, Jefferson expressed the pleasure it afforded him to see such proofs "that nature has given to our black brethren talents equal to those of the other colors of men, and that the appearance of a want of them is owing only to the degraded condition of their existence both in Africa and America." He also added that he desired "ardently to see a good system commenced for raising the condition both of their body and mind to what it ought to be." The copy sent to Jefferson was formally transmitted to M. de Condorcet, secretary of the Academy of Sciences at Paris, and member of the Philanthropic Society because, as he said, he "considered it a document to which your whole race had a right for its justification against the doubts which have been entertained of them." This recognition of Banneker's merit very naturally added greatly to his rapidly growing reputation at home, and brought to him hundreds of letters of congratulation from scholarly men throughout the civilized world.
