In 1900, Buffalo was the eighth largest city in America. It was located on one of the busiest sections of the Erie Canal, the terminus of the canal on the Great Lakes. Thanks to its location, Buffalo had huge grain milling operations and one of the largest steel mills in the country. Buffalo prospered during WWII as did many northern industrial cities. After the WWII, the manufacturing plants returned to the production of cars and industrial goods. The population rose to more than 500,000 in the mid-1950s. It is half that today. Buffalo was wounded irreparably by the de-industrialization of America.
