In the course of the nineteenth century some hydrothermal resorts, mainly located in the Austrian Alpine area and frequented by guests with modest incomes, managed to emerge from a situation of stagnation in which they were used only by the local population and their fame was confined to only a circumscribed geographical area, to assume the role of centres of international attraction. Several of these spas and health resorts developed through stages that were in many respects similar. These Kurorte attained their most substantial growth when they managed to achieve a business synergy between local and external economic forces interested in their development. The study of some cases of success reveals that there could be several forms of collaboration between external and local business interests and with the active involvement of the local public administration, which aimed at adjusting supply to demand. On the other hand, when the aim of entrepreneurship and capital from outside was not so much development of the Kurort as the marketing of a product produced at the spa, thus, when supply sought to impose new paradigms, which were to be accepted by demand, the Kurorte did not achieve any effective economic take-off.
