Doctor Peter, who married Miss Wheatley, 1775, was a man of business, tact, and talents--being first a grocer, and afterwards studied law, which he practised with great success, becoming quite wealthy by defending the cause of the oppressed before the different tribunals of the country. And who shone brighter in his day, than Benjamin Bannaker, of Baltimore county, Maryland, who by industry and force of character, became a distinguished mathematician and astronomer,--"for many years," says Davenport's Biographical Dictionary, "calculated and published the Maryland Ephemerides." He was a correspondent of the Honorable Thomas Jefferson, Secretary of State of the United States, taking the earliest opportunity of his acquaintanceship, to call his attention to the evils of American slavery, and doubtless his acquaintance with the apostle of American Democracy, had much to do with his reflections on that most pernicious evil in this country. Mr. Bannaker was also a naturalist, and wrote a treatise on locusts. He was invited by the Commission of United States Civil Engineers, to assist in the survey of the Ten Miles Square, for the District of Columbia. He assisted the Board, who, it is thought, could not have succeeded without him. His Almanac was preferred to that of Leadbeater, or any other calculator cotemporary with himself. He had no family, and resided in a house alone, but principally made his home with the Elliott family. He was upright, honorable, and virtuous; entertaining religious scruples similar to the Friends. He died in 1807, near Baltimore. Honorable John H.B. Latrobe, Esq., of Baltimore, is his biographer. In 1812, Captain Paul Cuffy was an extensive trader and mariner, sailing out of Boston, to the West Indies and Europe, by which enterprise, he amassed an immense fortune. He was known to the commercial world of his day, and, if not so wealthy, stood quite as fair, and as much respected, as Captain George Laws or Commodore Vanderbilt, the Cunards of America. Captain Cuffy went to Africa, where he died in a few years. James Durham, originally of Philadelphia, in 1778, at the early age of twenty-one, was the most learned physician in New Orleans. He spoke English, French and Spanish, learnedly, and the great Dr. Rush said of him, "I conversed with him on medicine, and found him very learned. I thought I could give him information concerning the treatment of diseases; but I learned from him more than he could expect from me." And it must be admitted, he must have been learned in his profession, to have elicited such an encomium from Dr. Rush, who stood then at the head of his profession in the country.
