Spa towns experienced a boom with the creation of rail lines that brought tourists to the resorts. These customers, beckoned by the climate and environment, sought healthful cures and leisurely activities. Resorts like those crafted by François Blanc at Bad Homburg and Monte Carlo exploded in part because they offered gambling, but they also grew because they were able to take advantage of the mechanization of travel in the mid-nineteenth century that developed in tandem with a culture of tourism. Industrialized transportation networks promoted industrialized forms of leisure even as they gestured to healthful living.
