Robert Walter (1841-1921) was born in Acton, Ontario, Canada, and died in Reading, Pennsylvania. During much of his youth he was in poor health, and he worked at various times as a store clerk, bookkeeper, and public school teacher. Following his marriage to Eunice C. Walter (b. Lippincott) in 1872, he lectured throughout the country on mental science. The Walters attended the Hygeio-Therapeutic College of New York and graduated as sanatorium physicians in 1873. The following year, they rented and ran The Mountain Home (later renamed Grand View Sanatorium) until 1876, when they founded Drs. Walter's Mountain Park (also called Walter's Park Sanatorium) in Wernersville, Pennsylvania. In 1886, Eunice wrote to Mary Baker Eddy that they were involved in healing work and would like to learn about Christian Science. Walter later graduated from the Hahnemann Medical College of Philadelphia in 1888. His published works include Vital Science Based Upon Life's Great Law: The Analogue of Gravitation (1899) and The Exact Science of Health (1903), which espoused fasting, homeopathic medicine, and vitalism. Walter was a Quaker.
