Episode notes
Mammoth Cave TB Experiment Turned Tragic
- Dr John Croghan tried treating TB by housing patients in Mammoth Cave in 1842 as a luxury underground health spa experiment.
- The group lived in roofless stone huts with oil lamps; five of fifteen died within five months and more after leaving the cave.
Sanatoria Emphasized Environment Over Cure
- Early 20th century sanatoria continued the idea of removing TB patients for recovery via controlled environment rather than effective medical cures.
- Physicians prized altitude, sunlight, ventilation and convalescence as primary therapies before antibiotics emerged.
Waverley Hills Expanded Into Gothic Sanatorium
- Waverley Hills grew from wooden pavilions in 1912 to a five-story Gothic red stone sanatorium completed in 1926 with room for 435 patients.
- The 1926 structure had long wings and many windows designed to maximize light and ventilation for TB therapy.
