BOONVILLE, a city and the county-seat of Cooper county, Missouri, U.S.A., on the right bank of the Missouri river, about 210 m. W. by N. of St Louis. Pop. (1890) 4141; (1900) 4377, including 1111 negroes; (1910) 4252. It is served by the Missouri Pacific, and the Missouri, Kansas & Texas railways. The city lies along a bluff about 100 ft. above the river. It is the seat of the Missouri training school for boys (1889), and of the Kemper military school (1844). Among its manufactures are earthenware, tobacco, vinegar, flour, farm-gates (iron), sash and doors, marble and granite monuments, carriages and bricks. Iron, zinc and lead are found in the vicinity, and some coal is mined. Boonville, named in honour of Daniel Boone, was settled in 1810, was laid out in 1817, incorporated as a village in 1839, and chartered as a city of the third class in 1896. Here on the 17th of June 1861, Captain (Major-General) Nathaniel Lyon, commanding about 2000 Union troops, defeated a slightly larger, but undisciplined Confederate force under Brigadier-General John S. Marmaduke. David Barton (d. 1837), one of the first two United States senators from Missouri, was buried here.
