DE ZENG, Frederick Augustus, Baron, soldier, b. in Dresden, Saxony, in 1756; d. in Clyde, N. Y., 26 April, 1838. He received a military education, and at the age of eighteen became lieutenant of the guard in the service of the landgrave of Hesse-Cassel. He saw service in Moravia and Bohemia, and in 1776 received the court appointment of gentleman of the chamber. He came to this country about the close of 1780 as captain of one of the Hessian regiments in the British service. He was honorably discharged from the German service in 1783, and in 1784 married an American lady and purchased an estate at Red Hook, N. Y. He was naturalized in 1789, and in 1792 commissioned major of a battalion of militia in Ulster county, N. Y., in which county he had become joint owner with Chancellor Livingston of a large tract of land. He was intimate with Gov. Clinton, interested like him in the opening of the interior water communications of the state, and personally surveyed in 1790-'2 the entire country from Albany to the Genesee river. He was connected with Gen. Schuyler in the Western Inland Lock Navigation company, and in 1796 was one of three who established near Albany a manufactory of window-glass, the first in the state, which proved a financial success until 1815, when it closed, owing to failure of fuel in the neighborhood. In 1812 he suggested measures that resulted in the improvement of the navigation of Seneca river and its associated lakes, and in 1814-'5 began what ultimately became the Chemung canal. He resided at Kingston, Ulster co., and later at Bainbridge, Chenango co., N. Y., where he built and owned the bridge over the Susquehanna river.
