History of Rochester, New York This article documents the history of Rochester, New York, in western New York State. Settlement 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 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, with headquarters of Eastman Kodak. In the 1970s it became fashionable to call the industrial cities along the Great Lakes 'rustbelt cities' following the move away from steel, chemical and other hard goods manufacturing. Rochester, with the presence of Ritter-Pfaulder, Bausch and Lomb, Eastman Kodak, Xerox, Gannett and other major industries, defied the trend for many decades following WWII.
