The Eugene Opie Papers includes extracts from diaries from several of his peers that illuminate his notable career in pathology, most especially his work on tuberculosis in Jamaica between 1937-1941. The Opie Papers include typed, loose diary notes from three of his peers: Wilbur A. Sawyer, John M. Weir, and Edward W. Flahiff. Sawyer supplies brief notes related to a pair of meetings within scientists in Montegomery (6/20-6/21/1937) and at Cornell University (11/17/1937). Weir's notes record one year of hospital and asylum work in Jamaica (2/1/1939-1/31/1940), with regular references to tuberculin tests, injections, and vaccinations. Of note, Weir devotes about a week to research Yellow Fever (4/1-4/8/1940). Finally, Flahiff offers the most exhaustive account of the Jamaica efforts. Contained in three folders, his notes span two and half years of work (10/1/1938-5/14/1941). Notably, Flahiff makes regular mentions of Opie, and notes that cultural issues impede their medical work. For example, he writes, "Birth control propaganda continues to be a serious deterrent to our nurses' efforts in the field" (3/7/1939). Perhaps most notably, Flahiff registers the effects of World War II obliquely in his entries. He notes a "new contingent of soldiers in Jamaica…composed of Canadians who have replaced the English troops in the Island" (7/1/1940) and glosses a public holiday for a "Peacemaker's Day" with the parenthetical "(Why???)" (11/9/1940). Together, these three sets of diaries ought to interest scholars researching Eugene Opie's career in pathology, especially his work to address tuberculosis in Jamaica.
