Herbert William Conn

Herbert William Conn, born on January tenth, eighteen fifty-nine, in Fitchburg, Massachusetts, was a prominent American bacteriologist and educator. The son of Reuben Rice Conn and Harriot Elizabeth, Conn faced health challenges in his youth due to rheumatic fever, which led to his withdrawal from public school. He received his education at Cushing Academy, a private institution in Ashburnham, Massachusetts, before matriculating to Boston University, where he graduated second in his class with an A.B. in eighteen eighty-one.

Conn continued his academic journey at Johns Hopkins University, earning his Ph.D. in eighteen eighty-four with a thesis titled 'Life-history of Thalassema,' for which he was awarded a Walker prize by the Boston Society of Natural History. In August eighteen eighty-five, he married Julia M. Joel, and together they had two children, including Harold J. Conn, who became a noted soil bacteriologist and stain expert.

After completing his education, Conn joined Wesleyan University as a biology instructor, quickly rising to the position of biology professor in eighteen eighty-seven and founding the university's biology department. He held this chair for the remainder of his career, also serving as acting director of the department of zoology at Martha's Vineyard Summer Institute. His teaching career included a stint at Trinity College and a directorship at the Cold Springs Biological Laboratory from eighteen ninety to eighteen ninety-seven.

In December eighteen ninety-eight, Conn played a pivotal role in founding the American Society for Microbiology, serving as its secretary for three years and later as president in nineteen hundred two. He became a bacteriology lecturer at the Connecticut Agricultural College in nineteen hundred one and was appointed Connecticut State Bacteriologist in nineteen hundred five, where he organized the State Bacteriological Laboratory. His expertise led to his appointment to the National Commission on Milk Standards by the New York Milk Committee in March nineteen eleven.

Throughout his career, Conn published over one hundred fifty papers and authored a series of school textbooks. He is particularly noted for his discovery that typhoid fever can be transmitted through oysters and for his specialization in the bacteriology of dairy products. A proponent of home economics, his text 'Bacteria, Yeasts, and Moulds in the Home' became a standard in home economics courses. Later in his career, Conn also challenged the emerging theories of eugenics, advocating for the consideration of social factors in understanding human outcomes.
