William Emery Merrill was born on 11 October 1837, at Fort Howard, Wisconsin. He was the son of Capt. Moses E. Merrill and Virginia (Slaughter) Merrill. His father, born in Maine, was of New England ancestry, being descended from Nathaniel Merrill who settled at Newbury, Massachusetts, in 1635; his mother came of an old Virginia family. When William was not quite ten, his father was killed while leading his troops in an attack at the battle of Molino del Rey, Mexico.
Because of the father's services, President Pierce, in 1854, appointed the son a cadet at the United States Military Academy. He graduated at the head of his class in 1859 and was assigned to the Corps of Engineers.
Throughout the Civil War, Merrill served as a military engineer, first in the Department of Ohio, subsequently in the Army of the Potomac and the Army of Kentucky, and finally, January 27, 1864, to June 27, 1865, as chief engineer of the Army of the Cumberland. During McClellan's campaign in West Virginia, he was captured, on September 12, 1861, and was a prisoner until the following February, except for two days in November when he escaped and was recaptured. Wounded in an engagement near Yorktown, Virginia, in April 1862, he was brevetted captain for gallantry. Subsequently, he served under Pope in the Cedar Mountain and Manassas campaigns and was then transferred to the West to fortify Covington and Newport, (September - October 1862) when threatened by Kirby-Smith's invasion of Kentucky. Promoted captain, March 3, 1863, he served under Rosecrans in the Chickamauga campaign, under Thomas in the battle of Missionary Ridge, and under Sherman in the advance on Atlanta. He was specially charged with the construction of fortifications for the protection of the railways supplying Sherman's army. For his services in the battles of Chickamauga, Lookout Mountain and Missionary Ridge, and Resaca and New Hope Church, he received the brevets of major, lieutenant-colonel, and colonel. His military services closed in 1870 after three years of duty on Sherman's staff as chief engineer of the Division of Missouri. As a military engineer, he was excelled by none. The second half of his career was devoted mainly to the river and harbor improvement work carried on by the Corps of Engineers. In 1870 he was charged with the improvement of this river and in 1878, at his own request, he was sent to Europe to study the improvement of non-tidal rivers by means of locks and movable dams. On his return, he advocated this method of improving Ohio and, after overcoming great opposition, in 1879 succeeded in securing from Congress an appropriation for the Davis Island lock and dam below Pittsburgh. These were completed in 1885 and led to the approval of his project, with some modifications, for the entire river. He lived long enough to build only the first lock and dam; the entire project was not completed until 1929 when the President of the United States took part in the celebration which announced its accomplishment. In 1870 Merrill published Iron Truss Bridges for Railroads and later he published studies of the improvement of non-tidal rivers and of inland navigation in France and the United States. In 1889 he was the United States representative at the Congress of Engineers in Paris.
