Abstract
Galveston, Texas is one of the oldest seaport cities in the Gulf of Mexico west of New Orleans, making it a historically prime location for disease outbreaks. The bubonic plague bacterium, Yersinia pestis, likely spread to Galveston via infected rats and fleas on steamboats. Known as the Black Death, the bubonic plague infected 17 Galvestonians from 1920 to 1921. This article examines the "War on Rats," the public health response to the Galveston bubonic plague outbreak in the 1920s. As part of public health practices at the time, the rat-proofing of buildings provides a glimpse into the intersection of public health and architecture. This exploration of the war on rats in Galveston offers insights into 20th-century examples of cross-disciplinary collaboration to promote human health in urban contexts.
