Information trouvée : Stephen Harriman Long, explorer and surveyor, son of Moses and Lucy (Harriman) Long, was born on December 30, 1784, in Hopkinton, New Hampshire, one of thirteen children. He graduated from Dartmouth College in 1809 and taught school for a time before entering the United States Army in December 1814 as a second lieutenant of engineers. He taught mathematics for two years at the United States Military Academy at West Point; in 1816 he was brevetted a major in the Corps of Topographical Engineers. In July he joined Gen. Henry W. Atkinson's "Yellowstone Expedition," bound from St. Louis to the Rocky Mountains aboard the United States Steamboat Western Engineer. In 1823 Long explored the sources of the Minnesota and Red rivers in the north and the United States-Canadian boundary west of the Great Lakes. He was brevetted a lieutenant colonel in 1826 and assigned by the War Department as consulting engineer to the Baltimore and Ohio Railroad in 1827. In that position he promoted the adaptation of wooden bridges to railroad use and formulated a series of tables for determining curves and grades, which he published in his important Rail Road Manual in 1829. Long remained with the B&O until 1830 and from 1834 to 1837 surveyed railroad routes in Georgia and Tennessee. For the next three years he was chief engineer of the Atlantic and Great Western Railroad, in which post he was promoted to regular major when the Topographical Engineers became a separate corps in 1838. Along with his army duties, Long continued his consulting services to various railroads until 1856, when he was put in charge of navigation improvements on the Mississippi. In 1861 he was promoted to colonel and called to Washington, D.C., to succeed Col. John J. Abert, father of James W. Abert, as commander of the Topographical Engineers. Long remained in that position until his retirement from the army in June 1863, three months after his corps had been merged with the Corps of Engineers. He died at his home in Alton on September 4, 1864.
