Daniel Fawcett Tiemann (January 9, 1805 – June 29, 1899)[1] was Mayor of New York City from 1858 to 1860.

[3] The Tiemann laboratory and factory was originally located on 23rd Street and Fourth Avenue in New York City, near Madison Square Park, later relocating uptown to Manhattanville in 1832.

[3] He was educated in a private seminary and at age thirteen began an apprenticeship in the drugstore of H. M. Schiefflin & Co., on Pearl Street, until 1824, when he joined his father's company.

Fed up with the corruption of Wood's administration, members of the Democratic Party's inner circle, powerful merchants such as August Belmont, John A. Dix, William Havemeyer, and John van Buren left the party and joined with reformers such as Peter Cooper, Republicans and Know-Nothings to create a fusion Independent Party.

[3] Tiemann Place, near 125th Street and Broadway in the New York City borough of Manhattan, and Tiemann Avenue, which extends from Pelham Parkway North to East 222nd Street in the northeastern part of the borough of the Bronx, are named for him.
