Joseph Moxon (8 August 1627 – February 1691), hydrographer to Charles II, was an English printer specialising in mathematical books and maps, a maker of globes and mathematical instruments, and mathematical lexicographer. He produced the first English-language dictionary devoted to mathematics, the first detailed instructional manual for printers, and the first English-language how-to books for tradesmen. In November 1678, he became the first tradesman to be elected as a Fellow of the Royal Society. Life Between the ages of around 9 and 11, Moxon accompanied his father, James Moxon, to Delft and Rotterdam where he was printing English Bibles. It was at this time that Moxon learned the basics of printing. Printer After the First English Civil War the family returned to London and Moxon and his older brother, James, started a printing business which specialized in the publication of Puritan texts, with the notable exception of A Book of Drawing, Limning, Washing or Colouring of Mapps and Prints of 1647 which was produced for Thomas Jenner, a seller of maps. In 1652, Moxon visited Amsterdam and commissioned the engraving of globe-printing plates, and by the end of the year was selling large celestial and terrestrial globes in a new business venture. He specialized in the printing of maps and charts, and in the production of globes, and mathematical instruments made of paper. Moxon's Mechanick exercises was published in parts between 1677 and 1684. It was completed in two volumes: the first giving instructions on metalworking, woodworking, brick-laying and sundial-construction, and the second (issued 1683–1684) providing a detailed series of instructions for printers, including typefounding, composition, press-work etc., which have given printing historians much (probably idealised) information on the working practices of hand-press period printing-houses. Hydrographer In January 1662, he was appointed hydrographer to the King, despite his Puritan background. His shop at this time was on Ludgate Hill; afterwards, in 1683, it was 'on the west side of Fleet Ditch,' but always 'at the sign of Atlas.'. Moxon theorized that the Arctic was ice free, and warmed by twenty-four hours of sunlight in the summer. He also speculated that Arctic ice was created near land, and that if one sailed far enough northwards, one would be free of northern land masses and, subsequently, ice. These views led him to believe that the Northwest Passage would be found by sailing near the North Pole. These views later influenced Daines Barrington
