James Chatham Duane (June 10, 1824 – December 8, 1897) was an engineering officer in the Union Army during the American Civil War, being the Chief Engineer of the Army of the Potomac.
Duane was born on June 10, 1824 in Schenectady, New York to James Duane and Harriet Constable. His paternal grandparents were James Chatham Duane (1769–1842) and Mary Ann Bowers (1773–1828). His great-grandfather James Duane (1733–1797) was a member of the Continental Congress and mayor of New York City. Duane graduated from Union College in 1844, where he was a founding member of Chi Psi fraternity, and from the United States Military Academy in 1848, where he ranked third in his class.
He taught practical military engineering there from 1852–54 during the superintendency of Robert E. Lee. Serving with the Army's company of sappers, miners, and pontoniers for nine years before the American Civil War, he led the engineers on a 1,100-mile march on the Utah Expedition in 1858 and commanded select engineer troops to guard President Abraham Lincoln at his inauguration in 1861.
Duane built the first military pontoon bridge over the Potomac River at the Battle of Harpers Ferry in 1862, served as Chief Engineer of the Army of the Potomac from 1863–65, and in seven hours in 1864 built the longest pontoon bridge of the Civil War (2,170 ft) across the James River.
