Notes:

     Appointed first "Professor of Bacteriology" in 1894; director of the Chicago Health Dept. Laboratories; and bacteriologist at Cook County Hospital.  Involved with Chicago Drainage Canal, and founded the Chicago Bureau of Food Inspection of which he was superintendent.  The EAB claims that he was "among the first to trace the indisputable connection between unhygienic conditions of living, carelessness in the protection of sources of food and water supply, neglect in their handling and distribution and the diseases....He preached the gospel of cleanliness as the first requisite of health... (He had a vision) that children should grow to maturity unhandicapped by physical conditions for which they were not responsible and which they could not improve." (5)

     In his Handkerchief study, he argued that they were a "nuisance to collect any kind of excrement about us and store it."   He chastised ladies who wiped the eyes of a lap‑dog, put the hanky back into a bag and then wave them in the wind in the presence of others.  "I think this distinctly dangerous, and the only waving of handkerchiefs that I would allow is when newlywed couples go away on the train and wave the handkerchief out the car window."  (8)

     While at the Dept. of Health Gehrmann mostly performed milk analysis and routine diphtheria examinations.   He also produced diphtheria antitoxin in 1894, and started water examinations in 1895, along with ice samples, and checks on smallpox vaccines and Widal tests.  He published a series of article dealing with the newly developed agglutination methods for diagnosis of typhoid fever, laboratory tests of smallpox vaccine, and for the control of the bacterial content of milk.  He authors one of the key reports for the "Streams Examinations" document used in the court case between Illinois and Missouri.

     At the 1900 meeting of the SAB, Gehrmann submitted "The Effect of Salt Solution and other Fluids on Bacteria Compared with Serum Reactions," which was read by title.
