This collection includes a set 45 glass lantern slides about leprosy; including the history, diagnosis treatment, transmission, pathogenicity, epidemiology of the disease. This slide presentation was originally labelled âMcCoy collectionâ and was probably created by the U.S. Public Health Service using photographs and data compiled by Dr. George McCoy (1876-1925). McCoy was director of the Leprosy Investigation Station in Hawaii, head of the Hygienic Laboratory / National Institute of Health in Washington, DC, and professor of public health and preventive medicine at Louisiana State University in New Orleans. See also OHA 225.03: McCoy Personal Papers Collection, 1938-1980; A Profile of the United States Public Health Service, 1798-1948 (Bess Furman, 1973); and The United States Public Health Service, 1798-1950 (Ralph Williams, 1951). Arrangement Note: According to the original inventory that accompanied the slides, this collection may be missing as many as 25 slides, including clinical photographs and data. The slides are arranged in numerical order. Missing slides are noted on the finding aid and captions are included when they are known.
