Detailed map of the Island of Jamaica and the Mosquito Coast, with the islands and shoals between, from Jefferys West India Atlas.
Thomas Jefferys (ca. 1719-1771) was a prolific map publisher based in London. His father was a cutler, but Jefferys was apprenticed to Emanuel Bowen, a prominent mapmaker and engraver. He was made free of the Merchant Taylors’ Company in 1744. Jefferys was the Geographer to Frederick Price of Wales and, from 1760, to King George III. He is most known today for his maps of North America, and for his central place in the map trade—he not only sold maps commercially, but also imported the latest materials and had ties to several government bodies for whom he produced materials.
Upon his death in 1771, his workshop passed to his partner, William Faden, and his son, Thomas Jr. However, Jefferys had gone bankrupt in 1765 and some of his plates were bought by Robert Sayer (1725-1794). Sayer, who had partnered in the past with Philip Overton (d. 1751), specialized in (re)publishing maps. In 1770 he partnered with John Bennett and many Jefferys maps were republished by the duo.
