Rogers Locomotive and Machine Works was a manufacturer of railroad steam locomotives based in Paterson, in Passaic County, New Jersey, in the United States. Between its founding in 1832 and its acquisition in 1905, the company built more than 6,000 steam locomotives for railroads around the world. Most 19th-century U.S. railroads owned 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. His son, Jacob S. Rogers, reorganized the company as Rogers Locomotive and Machine Works and 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 1901 American Locomotive Company (ALCO) merger by closing and reopening as Rogers Locomotive Works, but the company's independence lasted only until 1905, when ALCO purchased it. ALCO continued building new steam locomotives at the Rogers plant until 1913 and used the Rogers facilities through the 1920s as a parts storage facility and warehouse. Eventually, ALCO 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.
