 After a brief hospitalization in Basel, he spent 1889 in a sanatorium in Jena at the Binswanger Clinic, and in March 1890 his mother took him back home to Naumburg, where he lived under her care for the next seven years in the house he knew as a youngster. After his mother’s death in 1897, his sister Elisabeth—having returned home from Paraguay in 1893, where she had been working since 1886 with her husband Bernhard Förster to establish an Aryan, anti-Semitic German colony called “New Germany” (“Nueva Germania”)—assumed responsibility for Nietzsche’s welfare. In an effort to promote her brother’s philosophy, she rented the “Villa Silberblick,” a large house in Weimar, and moved both Nietzsche and his collected manuscripts to the residence. This became the new home of the Nietzsche Archives (which had been located at the family home for the three years preceding), where Elisabeth received visitors who wanted to observe the now-incapacitated philosopher.
