Banneker, Benjamin, 1731-1806
A negro mathematician; born in Maryland, Nov. 9, 1731.
He taught himself mathematics; and for many years, while engaged in daily labor, made the necessary calculations for and published an almanac for Maryland and the adjoining States.
Mr. Jefferson presented one of his almanacs to the French Academy of Sciences, where it excited wonder and admiration, and the African almanac became well known to the scientific circles of Europe.
In 1790 he was employed by the commissioners in the survey of the boundaries of the District of Columbia.
His grandmother was an Englishwoman, who purchased a small plantation in Maryland, bought two slaves from a ship just from Africa and married one of them.
He died in Baltimore, in October, 1806.

Callender, James Thompson 1792-1813
Editor and author; born in Scotland.
He published in Edinburgh, in 1792, a book called Political progress of Great Britain, which so offended the authorities that he was banished from the kingdom, and went to Philadelphia, where he published the Political register in 1794-95, and the American annual register for 1796-97.
He was a violent and unscrupulous opponent of Washington's administration, and delighted in abusing Hamilton and other Federalist leaders.
For a season he enjoyed the friendship of Jefferson.
The latter became disgusted with Callender, when the former, becoming Jefferson's enemy, calumniated him fearfully.
He published the Richmond Recorder, in which he made fierce attacks upon the character of Washington and Adams.
He died in Richmond, Va., in July, 1813.
