What we know
Sanatorium run in the late 1920s by Yosemite Nabona, whom the library's record calls a Navajo doctor: ten buildings on five acres, including a nurses' dormitory and a 35-by-70-foot main building (PPLD records of survey B21; the 1987 Black Forest Preservation Plan's Map 2 No. 21). Yosemite Nabona came about 1928 (Ellett), after a hurricane wrecked his Florida sanatorium (von Ahlefeldt). The Trumps gave the land: five acres (von Ahlefeldt) or two, with three more bought (Ellett). A 1929 Gazette article put spending at $60,000. He left in the early 1930s over 'marital troubles' (von Ahlefeldt p. 84), or was 'run out of town' in 1934 for practicing without a license (Ellett p. 24). The place was a Civilian Conservation Corps camp, the 'Black Forest Camp', in 1935-36, then a camp for transient girls (Ellett p. 25).
