February 4, 1909: Dr. John L. Leal testified at the second Jersey City trial about the first use of chlorine for continuous disinfection of a U.S. water supply at Boonton Reservoir, which was the water supply for Jersey City, New Jersey. The transcript from February 5, 1909, revealed that Leal had also installed a chloride of lime feed system at the filtration plant at Little Falls, New Jersey. He stated that he had experimented with chloride of lime addition some months before and that he was now using it daily. Thus, the trial transcript provides the first written evidence of the second continuous use of chlorine to disinfect a drinking water supply. This was also the first time chlorine was used in conjunction with mechanical filtration.

February 4, 1877: Charles-Edward A. Winslow is born. “Charles-Edward Amory Winslow (4 February 1877 – 8 January 1957) was an American bacteriologist and public health expert who was, according to the Encyclopedia of Public Health, “a seminal figure in public health, not only in his own country, the United States, but in the wider Western world.”
Winslow was born in Boston, Massachusetts and attended Massachusetts Institute of Technology (M.I.T.), obtaining a B.S. in 1898 and an M.S. in 1910.
He began his career as a bacteriologist. He met Anne Fuller Rogers when they were students in William T. Sedgwick’s laboratory at M.I.T., and married her in 1907. He taught at the Massachusetts Institute of Technology while heading the sewage experiment station from 1908 to 1910, then taught at the College of the City of New York from 1910 to 1914.
He was the youngest charter member of the Society of American Bacteriologists when that organization was founded in 1899. With Samuel Cate Prescott he published the first American textbook on the elements of water bacteriology.
In 1915 he founded the Yale Department of Public Health within the Yale Medical School, and he was professor and chairman of the Department until he retired in 1945. (The Department became the Yale School of Public Health after accreditation was introduced in 1947.) During a time dominated by discoveries in bacteriology, he emphasized a broader perspective on causation, adopting a more holistic perspective. The department under his direction was a catalyst for health reform in Connecticut. He was the first director of Yale’s J.B. Pierce Laboratory, serving from 1932 to 1957. Winslow was also instrumental in founding the Yale School of Nursing.
He was the first Editor-in-Chief of the Journal of Bacteriology, serving in that position from 1916 to 1944. He was also editor of the American Journal of Public Health from 1944 to 1954. He was curator of public health at the American Museum of Natural History from 1910 to 1922. In 1926 he became president of the American Public Health Association, and in the 1950s was a consultant to the World Health Organization.”
