English: In the Butler Building in Washington, D.C., the Hygienic Laboratory had room to spread out, which enabled many more physicians to make their way through Joseph Kinyoun’s training in bacteriology and public health. In this photo from about 1899 are Hill Hastings, Ezra Sprague, Kinyoun, Hugh Cumming, John Eager, William McIntosh, and Louis Williams. Cumming later became Surgeon General, Eager was an Assistant Surgeon General, and Williams became Chief Medical Officer on Ellis Island. Many other notable federal and state health officials trained at this precursor to the National Institutes of Health.
