The Szani opened its doors to fifteen children in 1911. In addition to adopting the methods of the well-known children’s sanatoriums and open-air schools, the creation of a homely space and a family atmosphere were also a primary consideration for Révész. Her aim was to examine, provide therapeutic assistance to, educate, and cure “nervous children and adolescents”. The ever-increasing number of children and the expansion of services enriched her goals. In the 1920s and 1930s, in addition to a staff of twenty-five (teachers, aides, doctors, and nurses), seventy children were cared for as students in the sanatorium and the forest school. The villa, which was extended with an annex, was joined by a new two-storey building. During the summer holidays, children and adults came for recuperation, and during the school year, boarding was also provided for children with behavioral problems who did not require medical treatment. A new feature was a four-class private forest school with public access, which admitted boys and girls in classes of 6–10. With their light furniture, they held their lessons on the covered terrace or outdoors. Every six months, the older children took formal differential examinations at other external schools to prove their progress. The natural environment was the most important tool for healing and education. Lessons were held outdoors, with tennis courts, swimming pools, sandpits, playgrounds and scout castles, and activities included gardening, outdoor woodwork and clay work. Cultural and historical excursions, including visits to art galleries and museums, were a frequent activity. At the Szani, individualized medical treatment and education was supplemented as necessary by physiotherapy, massage, hydrotherapy and bed rest. A dietetic and weight-gain diet was provided on request, supplementing those in need with blood-forming and strengthening agents. The Szani maintained its services during the economic crisis, helped by their own garden and farm. The children were also involved in animal care and crop production since “one of the unwritten laws of the Szani was that everyone cared for each other. Everyone tried to help by doing what he or she knew more about than the other.”
