Edwin O. (Edwin Oakes) Jordan

Born in Thomaston, Maine, in 1866, Edwin Oakes Jordan studied at the Massachusetts Institute of Technology, where he was influenced by bacteriologist William Thompson Sedgwick. He began his scientific career soon after graduating and went on to become one of the leading American voices in bacteriology and public health.

Jordan spent much of his career at the University of Chicago, where he built its Department of Bacteriology into an important center for research and teaching. He wrote widely used scientific books and papers, helped found The Journal of Infectious Diseases, and became known for clear, practical work on sanitation, water quality, food poisoning, and the spread of infectious disease.

Remembered as both a researcher and a teacher, Jordan stood at the point where laboratory science met everyday public health. His career reflects a time when bacteriology was transforming medicine, and he played a major part in bringing that new science into universities, public institutions, and public life.
