Malachy Postlethwayt (c. 1707 - 1767) was a British economist and commercial expert famous for his publication of the commercial dictionary titled The Universal Dictionary of Trade and Commerce in 1751. The dictionary was a translation and adaptation of the Dictionnaire économique of the French Inspector General of the Manufactures for the King, Jacques Savary des Brûlons. Malachy claims to have spent nearly 20 years adapting and researching his important dictionary, which attained a popular following. The second edition of the Dictionary issued in 1752, was updated with a series of fine maps based upon D'Anville's work, but updated by Postlethwayt to reflect his political and social views. Politically Postlethwayt was extremely conservative and highly patriotic though his views more often than not took the form of rants against the social and political enemies of the British Empire. In the mid-1740s Postlethwayt lobbied for the Royal Africa Company and was known for his pro-slavery advocacy. His belief that the slave trade had a place in the larger "political arithmetic" of empire, promoted through his many popular books and other publications, in time became the party line for the ruling class. Despite his misguided feelings about the Africa slave trade, Postlethwayt was an influential and thoughtful economist whose ideas influenced Adam Smith, Samuel von Pufendorf, Alexander Hamilton, and others. Postlethwayt also commonly spelled his name as Postlethawyte and Postlethwait. More by this mapmaker...

Solomon Boulton (fl. c. 1750-1775), sometimes written as 'Bolton,' was an English cartographer active in the middle part of the 18th century. Bolton's most notable works are the adaptions of Jean Baptiste Bourguignon d'Anville (1697 - 1782) maps published in conjunction with Malachy Postlethwayte's Dictionary of Commerce. These were later reprinted and embellished by Sayer and Bennett, and again by Laurie and Whittle. Learn More...

Thomas Kitchin (August 4, 1718 – June 23, 1784) was a London based engraver, cartographer, and publisher. He was born in London to a hat-dyer of the same name. At 14, Kitchin apprenticed under Emanuel Bowen, under whom he mastered the art of engraving. He married Bowen daughter, Sarah Bowen, and later inherited much of his preceptor's prosperous business. Their son, Thomas Bowen Kitchin, also an engraver joined the family business, which thereafter published in Thomas Kitchin and Son. From 1858 or so Kitchin was the engraver to the Duke of York, and from about 1773 acquired the title, 'Royal Hydrographer to King George III.' He is responsible for numerous maps published in the The Star, Gentleman's Magazine, and London Magazine, as well as partnering with, at various times, with Thomas Jefferys, Emmanuel Bowen, Thomas Hinton, Issac Tayor, Andrew Dury, John Rocque, Louis de la Rochette, and Alexander Hogg, among others. Kitchin passed his business on to his son, Thomas Bowen Kitchin, who continued to republish many of his maps well after his death. Kitchin's apprentices included George Rollos, Bryant Lodge, Thomas Bowen Kitchin, Samuel Turner Sparrow, John Page, and Francis Vivares. Learn More...
