Richard Wagner was a composer keenly aware of the state of his health and willing to go to great lengths to improve it. Like many Europeans of his era, Wagner often sought relief for his physical and mental afflictions at one of the region’s many spas. The basic principles of hydrotherapy dated back to Roman times, but the nineteenth century saw an explosion in the development of spa facilities and an accompanying profusion of professional and lay healers who proffered their healing methods to spa patrons of all classes. Offering a glimpse into the flourishing culture of water cures during Wagner’s time, this chapter illuminates key elements of the spa regimen, explores several of Wagner’s spa getaways and their curative aims, and weighs various views on diet, exercise, and hydrotherapeutic techniques promoted by nineteenth-century health advocates such as Vincenz Priessnitz and Sebastian Kneipp.
