PINNOCK, WILLIAM (1782–1843), English publisher and educational writer, was born at Alton, Hampshire, on the 3rd of February 1782, and was at first a schoolmaster, then a bookseller. In 1817 he went to London and, in partnership with Samuel Mander, began to publish cheap educational works. The f1rm's first productions were a series of Catechzsms, planned by Pinnock, consisting of short popular manuals, arranged in the form of question and answer, of the different departments of knowledge. They were followed by abridged editions of Goldsmith's histories of England, Greece and Rome, and a series of county histories which were no less profitable. Pinnock lost nearly all his money in outside speculation, and died in London on the 21st of October 1843. His son, William Henry Pinnock (1813–1885), a clergyman, was the editor and author of several elementary textbooks and scriptural manuals, and of various works on ecclesiastical law and usage.
