TYLER, Daniel, engineer, born in Brooklyn, Windham County, Connecticut, 7 January, 1799; died in New York city, 30 November, 1882. His father served in the Revolutionary army, and his mother was a granddaughter of Jonathan Edwards. After graduation at the United States military academy in 1819, as 2d lieutenant of light artillery, he served in garrison in New England in 1819-'24, and on the reorganization of the army, 1 June, 1821, he was made 2d lieutenant in the 5th infantry. In 1824-'6 he served in the Fort Monroe artillery-school for practice, of which he was for a time adjutant. He became 1st lieutenant in the 1st artillery on 6 May, 1824, and in 1826 commanded the Pikesville arsenal, near Baltimore, Maryland. While there he translated from the French a work on "Manoeuvres of Artillery," which led to his being sent to Europe in January, 1828, to obtain data for a more comprehensive work for the regular army. In April, 1829, he was admitted into the artillery-school of practice at Metz, and began a translation of the latest French system of artillery. The task was completed at the end of a year, and 300 lithographed copies in three volumes were sent to the war department in Washington, D.C. He also collected copies of every drawing and memoir connected with the French system of field, siege, sea-coast, and mountain artillery at a personal expense of about $2,000, which he offered to the government at Washington, provided a board should adopt the system for the United States artillery. This was not done, but he received from the government $1,600 for his collection of drawings. After his return in 1829 he was kept on ordnance duty to prepare a translation of the "School of the Driver," which in the French service is separate from the artillery. In 1830 he was sent to the Springfield armory to report upon the manufacture of small arms, and he was a member of the board that met to reorganize the national armories. In 1832 he was made superintendent of the inspectors of contract arms. He resigned on 31 May, 1834, became president of an iron and coal company in Lycoming county, Pennsylvania, and was sent to Great Britain to examine the methods of coal-mining and operating furnaces and rolling-mills. On his return in 1835 he erected the first coke hot-blast furnace that was built in this country, and succeeded in making pig-iron, but the operations of the company were suspended. In 1840 he became president of the Norwich and Worcester railroad, and completed the road. In 1843 he was appointed president and engineer of the Morris canal and banking company. In 1845-'9 he was president of the Macon and Western railroad, and he was afterward superintending engineer of the Dauphin and Susquehanna railroad and coal company and of the Auburn and Allentown railroad, and president and engineer of the Schuylkill and Susquehanna railroad company. At the beginning of the civil war he became colonel of the 1st Connecticut volunteers, 23 April, 1861, and commanded a division at the battles of Blackburn's Ford and Bull Run, 18-21 July, 1861. He was mustered out at the expiration of service on 11 August, 1861, but was reappointed in the United States volunteer service, with the rank of brigadier-general, on 13 March, 1862. He served with the Army of the Mississippi, engaged in the siege of Corinth from 29 April till 8 June, 1862, organized volunteer regiments in Connecticut from 13 August till 15 September, 1862, served on the military commission that investigated General Don Carlos Buell's campaign in Kentucky and Tennessee, 24 November, 1862, till 10 May, 1863, and guarded the upper Potomac, and was in command of Harper's Ferry and Maryland Heights in June. Afterward he was in command of troops in Baltimore, Maryland, and of the district of Delaware, and resigned his commission on 6 April, 1864.
