Frederick Gottlieb Niedringhaus (October 21, 1837 – November 25, 1922) was a German-born American businessman and politician.

[1] With his brother William, Niedringhaus started a tinware stamping company in the early 1860s, just as the Civil War fueled demand for tin products.

The brothers spent long hours at the factory, "engrossed in detail of production, or absorbed in plans to capture new markets, and sometimes even taking turns at the stamping machines when rush orders piled up.

"[2] With his brother, Niedringhaus developed a process for creating a decorative mottled surface on enameled metal in 1875.

The brothers also incorporated the Home Land & Cattle Company and bought a ranch at Little Dry Creek northwest of Miles City, Montana.

They bought ranches on Perico Creek near the town of Clayton, New Mexico, to serve as the N-N's winter range.
