In the 19th century, cities were grimy places, where thousands of people lived in overcrowded tenement buildings and walked streets polluted with trash, sewage, and the carcasses of dead animals. Unsurprisingly, these cities were also hotbeds of infectious disease.
One of the leading causes of death was tuberculosis, which spreads from person to person in the tiny droplets that spray through the air when an infected person coughs or sneezes. "In the 19th century, tuberculosis [was] the greatest single cause of death among New Yorkers," explains Anne Garner, the curator of rare books and manuscripts at the New York Academy of Medicine Library and the co-curator of the Museum of the City of New York’s new exhibition, "Germ City: Microbes and the Metropolis."
