George Grierson (1680 - October 27, 1753) was an Irish printer and publisher active in Dublin during the first part of the 18th century. Grierson began publishing when he married Jane Blow, a daughter of the prominent Irish paper making and publishing family of James Blow. In 1727, he was admitted as a Freeman to the city of Dublin and was appointed to the office of Printer General to His Majesty in Ireland. Operating under the title, 'Kings Printer in Dublin' from 1732 to 1753, Grierson was the only printer in Dublin allowed to print Holy Bibles. Later Grierson's attention turned toward cartography, which he identified as a profitable sideline to Bible work. Most of Grierson's cartographic work involved pirating the work of the prominent English eccentric and map publisher Herman Moll. Grierson's first 'Moll' piracies were published shortly following Moll's death in 1732. Though superficially identical to the maps in Moll's The World Describ'd, Grierson's maps are in fact complete re-engravings, often with new cartouche work bearing unique ‘Irishcentric' dedications and themes. Grierson also issued piracies of The English Pilot and Salmon's Modern History. Although George Grierson can be credited with few original maps, his work established Dublin as a center for cartographic engraving and publication in the 18th century. Today's Grierson's Irish versions of Moll's maps are far rarer than Moll's own work and are highly sought after by collectors. Following his 1753 death George Grierson's son, Boulter Grierson, took over the business, beginning a family printing dynasty that would last well into the 19th century. Grierson's offices were located at the 'Sign of the Two Bibles and King's Arms', Essex Street, Dublin.
