1846 U.S. Coast Survey Nautical Map of New York Bay and Newark Bay

The Office of the Coast Survey (1807 - present) 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 devised a labor intensive triangulation system whereby the entire coast was divided into a series of enormous triangles. These were in turn 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 losing congressional funding for the Coast Survey. Nonetheless, Hassler led 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 to 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) to accommodate topographic as well as nautical surveys. Today the Coast Survey is part of the National Oceanic and Atmospheric Administration or NOAA as the National Geodetic Survey. More by this mapmaker...

Andrew Atkinson Humphreys (November 2, 1810 - December 27, 1883) was a career U.S. Army officer. Born in Philadelphia, Pennsylvania, Humphreys came from an illustrious family. His grandfather is remembered as the 'Father of the American Navy', because he served as the chief naval constructor from 1794 - 1801, and designed the first U.S. warships, including the USS Constitution. Samuel Humphreys, Andrew's father, designed the USS Pennsylvania, the largest and most heavily armed ship at the time. Humphreys graduated from Nazareth Hall (modern day Moravian College and Theological Seminary), then entered the United States Military Academy at West Point. Humphreys graduated on July 1, 1831, was commissioned as a second lieutenant, and joined the Second Artillery Regiment. in South Carolina. In the summer of 1836, Humphreys and his regiment went to Florida to fight in the Seminole Wars. Disgusted by the war's mismanagement, Humphreys resigned his commission on September 30, 1836, and became a civil engineer. Nearly two years later, on July 7, 1838, Humphreys rejoined the U.S. Army as a 1st lieutenant in the Corps of Topographical Engineers. In 1844, Humphreys was put in charge of the Central Office of the U.S. Coast Survey in Washington, D.C. He received a promotion to captain in 1848. Humphreys began an extensive survey of the Mississippi River Delta in 1850, a project that lasted ten years. He also worked on the Pacific Railroad Surveys from 1853 - 1857. During these years just before the American Civil War, Humphreys earned a glowing reputation as a scientist both nationally and abroad. Humphreys was promoted to major at the beginning of the American Civil War and became the Army of the Potomac's chief topographical engineer. During the war, Humphreys fought beside McClellan during the Peninsula Campaign, when he was prmoted to brigadier general, given command of a division, and saw combat at the Battle of Antietam, the Battle of Fredericksburg, and the battle of Chancellorsville. He was transferred to a different division just before the Battle of Gettysburg, where, because of poor command decisions by his immediate superior, his division was annihilated. Humphreys was promoted to major general after the Battle of Gettysburg and consented to becoming General Meade's chief of staff, a position he had been offered in the days before Gettysburg. He served in this position until November 1864, when he was given command of the II Corps during the Siege of Petersburg. He held this command until the end of the war and his corps played a part in the Appomattox Campaign. After the war, Humphreys became Chief of Engineers in 1866, a position he held until he retired on June 30, 1879. Learn More...
