Edmund March Blunt (June 20, 1770 - 1862) was an American navigator, bookseller, chartmaker, and cartographer based in Newburyport, Massachusetts. Blunt was born in Portsmouth, New Hampshire in 1770. In 1796, along with the nominal assistance of prominent navigator Captain Lawrence Furlong, Blunt published The American Coast Pilot, one of the most important published works on American navigation. Although much of the work was plagiarized from British publications, the Coast Pilot was an immediate popular success. In response to the popularity of his work, Blunt published 21 subsequent editions, each with important updates and revisions. The first edition to contain map plates was printed in 1804. Following a fire that destroyed his offices at The Sign of the Bible in 1811, Blunt moved his business to New York and opened a new shop, The Sign of the Quadrant. His sons Edmund Jr. (1799 - 1866) and George William (1802 - 1878), joined the firm in 1824 and eventually took over the family business, renaming the firm 'E. and G. W. Blunt'. They both produced their own nautical books, charts, and instruments, as well as republished their father’s work. In 1830, Edmund accepted a position under Ferdinand Hassler at the United States Office of the Coast Survey. Much of Blunt's original work eventually found its way into U.S. Coast Survey Publications. George closed the firm in 1872 and sold the plates and chart copyrights to the U.S. Coast Survey and the U.S. Navy Hydrographic Office. Due to the quality and detail of Blunt's work, revised editions of his most important charts were republished well into the 1880s. More by this mapmaker...

William Hooker (fl. c. 1811 - 1846) was an important American geographer, surveyor, and engraver active in New York during the early part of the 19th century. He is responsible for a number of important maps and geographies particularly focusing on the New York area. As a young man, Hooker may have been apprenticed to Edmund March Blunt, the well established publisher of the New England Coast Pilot. What is certain, is that in 1819, Hooker married Eliza Carleton, Blunt's daughter. He went on to publish a number of nautical charts, school geographies, guide books, and atlases in conjunction with Blunt and others, including Humphrey Phelps, Peabody & Company, and A. W. Wilgus. Hooker passed away in 1846. Learn More...

George Gauld (October 26, 1732 - June 8, 1782) was a Scottish surveyor, painter, and military engineer active in the mid to late 18th century. Gauld was born in Ardbrack, Banffshire, Scotland and educated at King's College, Aberdeen. He subsequently served in 1861 briefly on the HMS Deptford while it was testing John Harrison's revolutionary marine chronometer. He served in North America during the French and Indian War (1754 - 1763). In the immediate aftermath of the war, between 1764 and 1781, he was made Surveyor General of West Florida assigned to survey the coast. Gauld's survey efforts ended in 1781 when Spain besieged Pensacola and invaded West Florida, capturing him. It is not clear if his survey work found its way into Spanish hydrographic charts, but it may have been incorporated into general Direccion Hidrografía knowledge. Gauld was repatriated to England in 1782 and died shortly after. His survey work remained unpublished throughout the American Revolutionary War (1775 - 1783), when the valuable data might have fallen into rebel hands. It remained the best and most detailed survey of the Gulf Coast until the work of the U.S. Coast Survey in the 1840s. Learn More...
