A fine example of the U.S. Coast Survey's 1867 nautical chart or maritime map of Brazos Santiago, Texas. This map focuses on the Brazos Santiago Pass, a narrow waterway between South Padre Island and Brazos Island. This area provides access from the Gulf of Mexico to the Madre Lagoon, an excellent natural harbor. The map identifies military installations at the northern tip of Brazos Island as well as the Point Isabel lighthouse Supposedly the island was named in 1519 by Alonso Alverez de Pineda. Later the natural port became exceptionally important for military control of the region. In 1846, it was the first military objective of the U.S. Navy in support of General Zackary Taylor's invasion of Mexico. Control over this important seaport was said by Harvard historian Leroy Graf to be the primary reason for the U.S. aggression against Mexico. During American Civil War Union soldiers occupied the island and its strategic harbor. From this island they staged the Brazos Santiago expedition. This expedition led to Battle of Palmito Ranch, the last battle of the Civil War. Issued under A. D. Bache for the 1866 edition of the U. S. Coast Survey Superintendent's Report.
The Office of the Coast Survey, founded in 1807 by President Thomas Jefferson and Secretary of Commerce 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, in response to a need for accurate navigational charts of the new nation's coasts and harbors. The spirit of the Coast Survey was defined by its first two superintendents. The first superintendent of the Coast Survey was Swiss immigrant and West Point mathematics professor Ferdinand Hassler. Under the direction of Hassler, from 1816 to 1843, the ideological and scientific foundations for the Coast Survey were established. These included using the most advanced techniques and most sophisticated equipment as well as an unstinting attention to detail. Hassler's devised a labor intensive triangulation system whereby the entire coast was divided into a series of enormous triangles. These were intern subdivided into smaller triangulation units that were then individually surveyed. Employing this exacting technique on such a massive scale had never before been attempted. Consequently Hassler and the Coast Survey under him developed a reputation for uncompromising dedication to the principles of accuracy and excellence. Unfortunately, despite being a masterful surveyor, Hassler was abrasive and politically unpopular, twice loosing congressional funding for the Coast Survey. Nonethelss, Hassler lead the Coast Survey until his death in 1843, at which time Alexander Dallas Bache, a great-grandson of Benjamin Franklin, took the helm. Bache was fully dedicated to the principles established by Hassler, but proved more politically astute and successfully lobbied Congress liberally fund the endeavor. Under the leadership of A. D. Bache, the Coast Survey completed its most important work. Moreover, during his long tenure with the Coast Survey, from 1843 to 1865, Bache was a steadfast advocate of American science and navigation and in fact founded the American Academy of Sciences. Bache was succeeded by Benjamin Pierce who ran the Survey from 1867 to 1874. Pierce was in turn succeeded by Carlile Pollock Patterson who was 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 (C & GS or USGS) to accommodate topographic as well as nautical surveys. Today the Coast Survey is part of the National Oceanic and Atmospheric Administration or NOAA.
