Amsterdam, New York, had a carpet manufacturing business that was started by John Stanford in the 1840s; the firm of Bigelow-Sanford left the city in 1955. Amsterdam was called the “Carpet City” by at least 1899, but the name is mostly historical today.

Amsterdam is a city located in Montgomery County, New York, United States. As of the 2010 census, the city had a total population of 18,620. The name is derived from the city of Amsterdam in the Netherlands.

The completion of the Erie Canal in 1825 was an economic boom to the city, which became an important manufacturing center. It was known for its carpets. In 1865, the population of Amsterdam was 5,135. By 1920, it was 33,524. Through the late 19th and early 20th centuries, it was a destination for immigrants from southern and eastern Europe, who initially worked in the factories.

ON THE Mohawk River, about 25 miles northwest of Albany, capital of New York, is Amsterdam, widely known as the “Carpet City of the World.” Fabric gloves, men’s shirts, dresses, pearl buttons, are other products that keep employment up, but rugs and carpets form Amsterdam’s industrial backbone. Not long ago some of the textile companies moved southward into the U. S. cotton-growing region, leaving hundreds of workers without jobs.

The Sanford family was instrumental in making Amsterdam the Carpet City. The first family member to move to Amsterdam was John Sanford, born in Roxbury, Conn., in 1803. He migrated to the Mohawk Valley as a young man and became a teacher and merchant. He served in Congress from 1841 to 1843.
 
After Sanford came home from Washington, he went into the carpet manufacturing business, bringing his son Stephen into the firm.
(...)
Former Sanford employees William McCleary, Samuel Wallin and David Crouse founded their own carpet mill in the 1880s.
