John Quincy Adams Nadenbousch (31 October 1824 – 13 September 1892) was a businessman, Confederate officer during the American Civil War and local politician in Martinsburg, West Virginia.
Early in life he had worked as a carpenter and proprietor of a Martinsburg lumber yard, and, by 1852, expanded his business affairs with the purchase of the Beeson flour mill, and soon established a distillery on the north side of Tuscarora Creek.
[citation needed] The distillery he built in Martinsburg in 1857 was destroyed during the Civil War but was rebuilt in 1863 and became the Hannis Distilling Company.
When the federal armory at Harpers Ferry was attacked by John Brown, on October 16, 1859, Nadenbousch's company was one of the first to respond.
On account of impaired health, and at his own request, Nadenbousch was relieved later that summer, from duty in the field, and assigned to the command of the post at Staunton, Virginia.
Beginning in 1870, he became Marshall of the Martinsburg Fire Company, and he also maintained membership in the Tuscarora Lodge of the Independent Order of Odd Fellow, and was an officer of the Berkeley County Agricultural and Mechanical Association.
