Daniel Fawcett Tiemann

Daniel Fawcett Tiemann was the mayor of New York from 1858 to 1860. He was a founding trustee of the Cooper Union for the Advancement of Science and Art. Tiemann was an industrialist, who lived in Manhattanville where he owned D.F. Tiemann & Company Paint & Color Works which manufactured pigments and paints. This business had been started originally in 1804 by his father, I. Anthony Tiemann, with his brother, Julius William Tiemann, and Nicholas Stippel. His father retired from the business in 1839.

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. He became a partner in the company in 1826.

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.

His paternal uncle, Julius William Tiemann, was one of the founding partners in the D.F. Tiemann company, and father of Hermann Newell Tiemann (1863–1957), who was a commercial photographer in New York City.

D.F. Tiemann was nephew-in-law of Peter Cooper, the American industrialist and inventor. In 1826, he had married Martha Clowes, Cooper's niece, and they had three sons and three daughters.
