quantities of water. Priessnitz's treatments also included a great deal of less strenuous exercise, mostly including walking. Ultimately, Priessnitz's clinic was extremely successful, and he gained fame across the western world. His practice even influenced the hydropathy that took root overseas in America. Sebastian Kneipp (1821–1897) Sebastian Kneipp was born in Germany and he considered his own role in hydropathy to be that of continuing Priessnitz's work. Kneipp's own practice of hydropathy was even gentler than the norm. He believed that typical hydropathic practices deployed were "too violent or too frequent" and he expressed concern that such techniques would cause emotional or physical trauma to the patient. Kneipp's practice was more all encompassing than Priessnitz's, and his practice involved not only curing the patients' physical woes, but emotional and mental as well. Kneipp introduced four additional principles to the therapy: medicinal herbs, massages, balanced nutrition, and "regulative therapy to seek inner balance". Kneipp had a very simple view of an already simple practice. For him, hydropathy's primary goals were strengthening the constitution and removing poisons and toxins in the body. These basic interpretations of how hydropathy worked hinted at his complete lack of medical training. Kneipp did have, however, a very successful medical practice in spite of, perhaps even because of, his lack of medical training. As mentioned above, some patients were beginning to feel uncomfortable with traditional doctors because of the elitism of the medical profession. The new terms and techniques that doctors were using were difficult for the average person to understand. Having no formal training, all of his instructions and published works are described in easy to understand language and would have seemed very appealing to a patient who was displeased with the direction traditional medicine was taking. A significant factor in the popular revival of hydrotherapy was that it could be practised relatively cheaply at home. The growth of hydrotherapy (or 'hydropathy' to use the name of the time), was thus partly derived from two interacting spheres: "the hydro and the home". Hydrotherapy as a formal medical tool dates from about 1829 when Vincenz Priessnitz (1799–1851), a farmer of Gräfenberg in Silesia, then part of the Austrian Empire, began his public career in the paternal homestead, extended so as to accommodate the increasing numbers attracted by the fame of his cures. At Gräfenberg, to which the fame of Priessnitz drew people of every rank and many
