Before antibiotics, a tuberculosis diagnosis came with a prescription for months of rest, fresh air and rich food in a scenic setting. This episode traces the sanatorium from English physician George Bodington, whose 1840 essay on cold air and beef, wine and milk was dismissed by The Lancet as very crude ideas, to Hermann Brehmer’s 1863 facility in Silesia, which proved the model at scale. It explains why it helped: TB bacteria survive inside macrophages, so the body walls them off in granulomas, and rest and nutrition supported that effort. The name itself came from the Latin verb sanare, to heal.

Sanatoriums spread from Saranac Lake, New York, to the Swiss Alps and to Alvar Aalto’s Paimio Sanatorium in Finland, completed in 1933 with a chair reclined at 110 degrees and silent sinks. In the United States, Asheville and Arizona marketed their climates, and penniless migrants ended up in tent camps like Sunnyslope, with 7,000 arriving in Tucson by 1920. Black Americans were largely excluded. Albert Schatz’s 1943 discovery of streptomycin emptied the buildings in the West, while Soviet sanatoriums became worker spas.
