Rogers Locomotive and Machine Works was a 19th-century manufacturer of railroad steam locomotives based in Paterson, in Passaic County, New Jersey, in the United States. It built more than six thousand steam locomotives for railroads around the world. Most railroads in 19th-century United States rostered at least one Rogers-built locomotive. The company's most famous product was a locomotive named The General, built in December 1855, which was one of the principals of the Great Locomotive Chase of the American Civil War.
The company was founded by Thomas Rogers in an 1832 partnership with Morris Ketchum and Jasper Grosvenor as Rogers, Ketchum and Grosvenor. Rogers remained president until his death in 1856 when his son, Jacob S. Rogers, took the position and reorganized the company as Rogers Locomotive and Machine Works. The younger Rogers led the company until he retired in 1893. Robert S. Hughes then became president and reorganized the company as Rogers Locomotive Company, which he led until his death in 1900.
Rogers avoided the American Locomotive Company (ALCO) merger in 1901 through closing and reopening as Rogers Locomotive Works. The company remained independent until 1905, when ALCO purchased it; ALCO continued building new steam locomotives at the Rogers plant until 1913. ALCO used the Rogers facilities through the 1920s as a parts storage facility and warehouse, but eventually sold the property to private investors. Today, several Rogers-built locomotives exist in railroad museums around the world, and the plant's erecting shop is preserved as the Thomas Rogers Building; it is the current location of the Paterson Museum, whose mission is to preserve and display Paterson's industrial history.
