Laurie & Whittle refers to the partnership of Robert Laurie (1755?-1836) and James Whittle (1757-1818), engravers and map publishers. Both men were employed by Robert Sayer (ca. 1724-1794), one of the most prominent British publishers and map sellers of the eighteenth century. Sayer died in 1794 and his business was taken over by his assistants. The two worked together as Laurie & Whittle until 1812, when Laurie retired. They were especially known for publishing sea charts and maritime atlases. From 1812-1818, when he died, Whittle worked with Laurie’s son, Richard Holmes Laurie, as Whittle & Laurie. After 1818, the firm was known as R. H. Laurie, even though Richard died in 1858. Later, the firm was managed by Laurie’s draughtsman, Alexander George Findlay, and, later, Daniel and William Kettle.
Samuel Dunn (bap. 1723-1794) was a teacher of mathematics and navigation who published, among other things, maps and charts. Although information about his early education is lacking, by age nineteen he was leading his own school and teaching writing, accounting, navigation, and mathematics in Devon. In 1751, he moved to London, where he taught in several schools and tutored privately.
By the 1760s, Dunn was known as a respected astronomer and had published a range of textbooks on math, navigation, and astronomy. After the publication of the Nautical Almanac, Dunn acted as a certifier of ships’ masters under the new system, on behalf of the Board of Longitude. He performed similar work for the East India Company, as well as made charts of the East Indies. In 1776 he published A New Variation Atlas and, in 1777, A New Epitome of Practical Navigation, or, Guide to the Indian Seas. By 1780, he was named editor of the New Directory for the East Indies, which included his own charts. In 1786, he released a pioneering study, Theory and Practice of Longitude at Sea. He also designed several instruments for navigation.
Dunn died at his home in Fleet Street in January 1794. His books and maps were auctioned at Sothebys in a sale of over 1,000 lots. Many of these were bought by Alexander Dalrymple, hydrographer of the East India Company and soon-to-be-named first head of the Hydrography Office.
