Big Apple
"The Big Apple" was popularized as a name for New York City by John J. Fitz Gerald in a number of horse-racing articles for the "New York Morning Telegraph" in the 1920s. The earliest of these was a casual reference on 3rd May, 1921:
Western New York
The two major Western New York cities, Buffalo and Rochester, benefited greatly from the opening of the Erie Canal. With its strategic position at the western end of the Erie Canal, the eastern end of Lake Erie and proximity to Niagara Falls and Canada, Buffalo emerged as a major port. Niagara Falls provided Buffalo with a ready supply of power, so much so that one of its enduring nicknames is "The City of Light". Buffalo experienced steady growth during the 19th century and at one point was one of the 10 most populated cities in the United States. According to some, Rochester was "America's First Boomtown" and was a key player in the flour industry (hence its initial nickname "Flour City"). Its growth was attributed to both the completion of the Erie Canal and its resulting significance in the flour industry. Olean was originally planned to be a similar major hub, but it proved to be at a major disadvantage: located near the headwaters of the Allegheny River (a factor its planners had hoped would make the city a gateway to the Midwest), the river was too shallow to support large boat travel or shipping on a consistent basis. As a region, Western New York played a significant role in the American economy during the 19th century. Large scale immigration from Ireland, Italy, Poland, Great Britain and Germany soon followed into the region.
