|Typhoid Fever in Chicago, 1892
Chicagoans were very concerned with the onset of typhoid in the year before the World's Columbian Exposition. This article by William T. Sedgwick, a professor of biology at Massachusetts Institute of Technology, and Allen Hazen, a chemist at the Lawrence Experimental Station in Massachusetts, originally appeared in the Engineering News and American Railway Journal in April 21, 1892. The authors expressed concern about water polluted by sewage and the “makeshifts and expedients” that characterized Chicago’s sanitary history.
