1879 Raynolds Civil War Map of Vicinity of Gauley Bridge, West Virginia

William Franklin Raynolds (March 17, 1820 - October 18, 1894) was an American explorer, engineer, and U.S. Army officer. Born in Canton, Ohio, Raynolds was the fourth of six children to William Raynolds and Elizabeth Seabury. Raynolds entered the United States Military Academy at West Point on July 1, 1839 and graduated fifth in his class of thirty-nine in 1843. Initially commissioned as a second lieutenant and posted with the 5th U.S. Infantry, he was soon transferred to the U.S. Army Corps of Topographical Engineers. His first assignments were as an assistant topographical engineer involved in improving navigation of the Ohio River and then mapping the northeastern boundary of the United States. During the Mexican-American War, Raynolds served in Winfield Scott's campaign which marched overland from Veracruz to Mexico City. After the war and during the occupation, Raynolds and a few other engineers decided to map and explore the nearby mountains. He and his party are credited as being the first to summit Pico de Orizaba, the tallest mountain in Mexico and the third tallest in North America. After returning from Mexico, Raynolds again took up the project of surveying the northern border of the United States. This project, however, did not last long, as Raynolds was soon assigned a project to develop water sources for Washington, D.C. and then was tasked with surveying and mapping the shorelines of the Great Lakes while identifying potential lighthouse locations. In 1857, he designed and supervised the construction of lighthouses along the Jersey Shore and the Delmarva Peninsula. In early 1859, Raynolds was given the task of leading an expedition into the Yellowstone region of Montana and Wyoming with the goal of determining, 'as far as practicable, everything relating to...the Indians of the country, its agricultural and mineralogical resources...the navigability of its streams, its topographic features, and the facilities or obstacles which the latter present to the construction of rail or common roads.' Raynolds and his party would spend the next two years in the West and was the first federally funded party to enter Jackson Hole or observe the Teton range. The American Civil War, however, would keep Raynolds from presenting his findings until 1868. At the outbreak of the Civil War, Raynolds made his way back to Washington, D.C. where he was named chief topographic engineer of the Department of Virginia in July 1861. As no suitable maps of Virginia existed for military use, Raynolds and his team immediately set to work surveying and mapping the part of Virginia that remained loyal to the Union. This part of the state would become the State of West Virginia in 1863. In January 1863, Raynolds was put in charge of the defense of Harper's Ferry, West Virginia, but by 1864 hostilities in the West, particularly with the Sioux Indians, made Raynold's knowledge of the Great Lakes more valuable than his understanding of the defenses of Harper's Ferry. He was transferred in April and would not see any more combat for the rest of the war. After the war, Raynolds remained in the Army Corps of Engineers and worked on various projects, including improving the navigation of the Arkansas, Missouri, and Mississippi River, building harbors, and overseeing lighthouse construction. Raynolds retired from the Corps of Engineers in 1884, after a forty year career. We know very little about Raynold's private life, however, we do know that he married young and he and his wife did not have any children. More by this mapmaker...

William C. Margedant (November 15, 1835 - January 12, 1900) was a German-American engineer and U.S. Army soldier. Born in Dusseldorf, Germany (then Prussia), Margedant was educated in Germany and immigrated to the United States in 1854. He settled in Cincinnati, Ohio, where he was employed by C.A. Latta and assisted in constructing the first steam fire engine in the United States. He then started working as a machinist in Hamilton, Ohio, in the shops of Owens, Lane, and Dyer and eventually began working for the Bentel and Margedant Company, which designed and manufactured wood working machinery. In 1861, Margedant volunteered to serve in the Union army and organized a company of forty-eight volunteers from Hamilton. This company then joined the Ninth Ohio Volunteer Infantry in Cincinnati and Margedant was elected captain of his unit. Margedant, after his first three month enlistment was up, was appointed to the topographical engineers on the staff of General William Starke Rosecrans (September 6, 1819 – March 11, 1898). He was involved in the organization and compilation of the first detailed topographic maps of West Virginia. While serving on Rosecrans's staff, Margedant

invented method of duplicating maps in the field by which all corps, divisions and brigades, as well as individual regiments when acting or moving alone, were furnished at each camp with maps of the surrounding country on the march, with those showing the roads, streams and other military features of country in advance. These maps were printed on cloth, often on a handkerchief and distributed in great numbers. Photographic duplications of charts gave valuable information as to camp grounds, water forage, kind of roads and trails and their condition. Every organization down to brigades had a topographical engineer whose business it was to gather daily all the information possible of the country where the troops halted, and of the region in advance, and reported it in the evening to the next superior headquarters. At army headquarters Capt. Margedant's force consolidated the topographical notes received, and the next day maps and charts containing everything ascertained the day before were in the hands of all commanding officers.

Walter Angelo Powell (January 6, 1829 - May 21, 1911) was an American architect and engineer. Born in Baltimore, Maryland, and received an education in Baltimore and Philadelphia in medicine before moving to New York City to study architecture. After five years of study, he worked as an architect in New York City for a time before returning to Baltimore, where he studied civil engineering and worked with on topography for the Baltimore and Ohio Railroad. he then became associate with Robert Mills, an architect of public buildings in Washington, D.C. With Mills, Powell worked on designs for the extension of the United States Capitol, the Washington National Monument, the Marine Hospital, and other public buildings. He then moved to Cincinnati, where he opened his own firm, and was successful until the outbreak of the American Civil War. He then was convinced by General Rosecrans to join his staff in Virginia and served through the entire war. He was in twenty-four engagements and planned and built the fortifications at Harper's Ferry, among other locations. After the war, Powell moved to Nashville, Tennessee and became an engineer with a large mining company. After losing all his money speculating on oil wells, he returned to Cincinnati, and, finding the city 'full of architects', he turned his sights to Missouri. He arrived in St. Joseph, Missouri, in 1866, and developed a reputation as one of the best architects in the West. Powell married Celia Gillmyer in 1857, with whom he had seven children. Learn More...
