1861 U.S. Coast Survey Chart or Map of the Coast of Georgia and South Carolina

Beautifully detailed chart showing the triangulation of the coast of Georgia and South Carolina.

This is an appealing 1861 U.S. Coast Survey triangulation chart or map of the Georgia and South Carolina coastline from Cumberland Island to Bald Head Island in North Carolina. E essentially three maps on a single sheet, the top map features a triangulation of the coast from Bull’s Island to Savannah River. The bottom map extends from Ossabaw Island to Cumberland Island. The center map focuses on the coastline from Cumberland Sound in Georgia to Cape Fear in South Carolina. Focuses on the inlets and waterways, indicates, lighthouses and important channels and shows the progress of the survey work in this area by date-annotated sections. Nautically this map offers a wealth of practical information for the Mariner, including countless depth soundings and notes on light hoses, tides, shoals, and other undersea dangers.

This map was compiled under the direction of A. D. Bache, Superintendent of the Survey of the Coast of the United States and one of the most influential American cartographers of the 19th century, and issued in the 1861 edition of the Superintendent's Report.

Cartographers

The Office of the Coast Survey (1807 - present), founded in 1807 by President Thomas Jefferson and Secretary of the Treasury Albert Gallatin, is the oldest scientific organization in the U.S. Federal Government. Jefferson created the "Survey of the Coast," as it was then called, to produce accurate navigational charts of the new nation's coasts and harbors. The first two superintendents defined the spirit of the Coast Survey. The Coast Survey's first superintendent was Swiss immigrant and West Point mathematics professor Ferdinand Hassler. Under Hassler's direction, from 1816 to 1843, the Coast Survey established its ideological and scientific foundations. These included the use of the most advanced techniques and most sophisticated equipment, along with unstinting attention to detail. Hassler devised a labor-intensive triangulation system that divided the entire coast into a series of enormous triangles. These were then subdivided into smaller triangulation units, which were individually surveyed. No one had ever attempted this exacting technique on such a massive scale. As a result, Hassler and the Coast Survey under his leadership earned a reputation for uncompromising dedication to accuracy and excellence. Unfortunately, despite being a masterful surveyor, Hassler was abrasive and politically unpopular, and Congress cut funding for the Coast Survey twice. Nonetheless, Hassler led the Coast Survey until his death in 1843, when Alexander Dallas Bache, Benjamin Franklin's great-grandson, took the helm. Bache was fully dedicated to the principles established by Hassler, but proved more politically astute and successfully lobbied Congress to fund the endeavor generously. Under A. D. Bache's leadership, the Coast Survey completed its most important work. During his long tenure with the Coast Survey, from 1843 to 1865, Bache steadfastly advocated American science and navigation and, in fact, founded the American Academy of Sciences. Benjamin Pierce succeeded Bache and ran the Survey from 1867 to 1874. Pierce was succeeded by Carlile Pollock Patterson, Superintendent from 1874 to 1881. In 1878, under Patterson's superintendence, the U.S. Coast Survey was reorganized as the U.S. Coast and Geodetic Survey (USCGS) to accommodate both topographic and nautical surveys. Today, the Coast Survey is part of the National Oceanic and Atmospheric Administration (NOAA) as the National Geodetic Survey.   Further Details...

Alexander Dallas Bache (July 19, 1806 - February 17, 1867) was an American physicist, scientist, and surveyor. Bache is best known in cartographic circles as the Superintendent of the U.S. Coast Survey from 1843 to 1865. Born in Philadelphia, Bache, a great-grandson of the statesman and inventor Benjamin Franklin, had a varied career primarily focused on education. He toured Europe on behalf of Girard College and composed an important treatise on European Education. Later he served as president of Philadelphia's Central High School and was a professor of natural history and chemistry at the University of Pennsylvania. On the death of Ferdinand Rudolph Hassler (1770 - 1843), Bache was appointed Superintendent of the United States Coast Survey. Picking up where Hassler left off, Bache presided over the Survey during its most prolific period and oversaw the mapping of most of the United States coastline. To this day his name appears on countless marine pilot books and U.S. Coast Survey nautical charts. For his work, he was elected Associate Fellow of the American Academy of Arts and Sciences, a Fellow of the Royal Society of Edinburgh, and a Foreign Member of the Royal Society. Following the Civil War, Bache was elected a 3rd Class Companion of the Military Order of the Loyal Legion of the United States. He died in Newport, Rhode Island, and was buried in the Congressional Cemetery in Washington, DC, where he is commemorated by a monument designed by American architect Henry Hobson Richardson.   Further Details...
