POULSON, Zachariah, publisher, born in Philadelphia, Pennsylvania, 5 September, 1761; died there, 31 July, 1844. His father, of the same name, was brought from Denmark to Philadelphia in infancy, and became a printer. The son was a pupil of Christopher Sower, in whose printing establishment at German-town, Pennsylvania, was printed, in German, the first edition of the Bible published in the United States. For many years he was printer to the senate of Pennsylvania. On 1 October, 1800, he began the publication of the "American Daily Advertiser," the first daily in the United States, which he had purchased from David C. Claypoole, and he continued as its editor and proprietor till its discontinuance, 28 December, 1839. He issued " Poulson's Town and Country Almanac" (1789-1801), and was the publisher of Robert Proud's " History of Pennsylvania" (1797-'8), the mystical works of William Gerar de Brain, and other valuable books. He was a founder and president of the Philadelphia society for alleviating the miseries of public prisons, and a member and benefactor of various other benevolent associations. He was also for twenty-one years librarian of the Library company of Philadelphia, six years its treasurer, and thirty-two years a director, and his portrait, by Thomas Sully, hangs in its hall in that city.

Anti-Papal Polemic, 1788 — Loooooong Footnotes in TINY Print
Crawford, Charles. Observations upon the downfall of the papal power, and the consequent events...a new edition. Philadelphia: Zachariah Poulson, Jun., 1788. 12mo (18 cm, 7.1"). 42 pp. (lacking pp. 43–44 [bookseller's adv.]).
•No holdings of any earlier edition of this scarce and controversial polemic, which closes with a justification of the use of violence in overthrowing the Papacy, could be located. Crawford, who sometimes called himself earl of Crawford and Lindsay, published works on an interesting array of topics including slavery, the Antichrist, and the descent of the Native Americans "from the Ten Tribes."The present work relies partially on biblical exegesis and partially on sensationalism (tortures of the Inquisition are luridly described, and unnatural lusts of the Turks denounced) to make its case against the Catholic Church.
