Asiatic Cholera Epidemic breaks out in Boston.

[6/3-Puleo] The initial outbreak is centered around Half Moon Place and Burgess Alley on Fort Hill. The epidemic eventually kills over 500 residents, mostly Irish immigrants, whose life expectancy city health inspector Lemuel Shattuck estimates at the time is 14 years. Norman Ware later describes a visit by Dr. Henry Clark to the cellar of a house on Half Moon Place in which 39 persons were living, and to the flooded cellar of another house, in which a child’s body “was actually sailing about the room in its coffin.” However, Boston suffered fewer deaths than other large U.S. cities that also experienced similar epidemics at the time.
