Charles Frederick Zimpel
Charles Friedrich Zimpel (December 11, 1801 - June 26, 1879) was a German architect who designed buildings in New Orleans, Louisiana, U.S. from 1830 to 1837; and later, in 1864, the plan for the Jaffa to Jerusalem railway line. In particular, he designed the Bishop's City Hotel in 1831, the Bank of Orleans in 1832, as well as the Banks Arcade and the Orleans Cotton Press in 1833.<https://www.lahistory.org/resources/dictionary-louisiana-biography/dictionary-louisiana-biography-z/ Charles F., surveyor, engineer, cartographer, architect. Probably came to New Orleans as the surveyor and engineer for the course of the  New Orleans and Carrollton Railroad (now the St. Charles Avenue streetcar line); also spent the years 1831-1832 compiling surveys for the production of the map “Topographical Map of New Orleans and Its Vicinity . . . “, which he had engraved in Prussia, probably his native country. The map includes the first survey of the town of Carrollton (now the upper limits of New Orleans) done by Zimpel. In 1834, he is listed as deputy city surveyor and engineer. Zimpel was the architect for four New Orleans buildings, all designed and built in the 1830s: the Bank of Orleans, Banks Arcade, Bishop's  City Hotel, and Orleans Cotton Press. He also remodeled the Charity Hospital building as the State House. Apparently left New Orleans by the late 1830s. By 1864, he was in Constantinople, where as “Ingénieur en chef” he drew up plans for the proposed Jaffa to Jerusalem railway line. J.A.M.
