Settlement of the city of Rochester in western New York State began in the late 18th century, and the city flourished with the opening of the Erie Canal. It became a major manufacturing center, and attracted many Italians, Germans, Irish and other immigrants, as well as a dominant group of Yankees of New England origin. The Yankees made Rochester the center of multiple reform movements, such as abolitionism and women's rights. It was famous as the center of the American photography industry and the headquarters of Eastman Kodak. In the 1970s it became fashionable to use the term "Rust Belt" for the industrial cities along the Great Lakes following the move away from steel, chemical and other hard goods manufacturing. Rochester, with the presence of Ritter-Pfaudler, Bausch and Lomb, Eastman Kodak, Xerox, Gannett and other major industries, defied the trend for many decades following World War II.
Of the 19 places in the United States named "Rochester", at least 8 were named directly after the city, having been founded or settled by former residents. These include: Rochester, Indiana; Rochester, Texas; Rochester, Iowa; Rochester, Kentucky; Rochester, Michigan; Rochester, Minnesota; Rochester, Nevada; and Rochester, Ohio.
