For centuries consumption was a fashionable, even beautiful death, until Robert Koch showed on March 24, 1882 that it was an infection. The episode traces tuberculosis from an ancient burial through the Romantic age to crowded industrial cities, and New York's first reporting rules and spitting law. It closes on the great argument over whether better food and living conditions, rather than medicine, brought the disease down.
Why tuberculosis declined is still debated: McKeown credited nutrition and living standards, Szreter public health politics, and others isolation of the infectious and ridding cattle of TB. The age of the disease is also argued, as is how far the Romantic ideal of consumption reached beyond the comfortable classes.
