Trudeau, Edward Livingston (trōˈdō) [key], 1848–1915, American physician, b. New York City, M.D. Columbia, 1871. As a result of taking care of his brother, who had tuberculosis, he developed the disease. He went to live in the Adirondacks, spending much time in the open, and regained his health. Seeking to aid others suffering from tuberculosis, he founded (1884) at Saranac Lake the Trudeau Sanatorium, where he employed the open-air treatment of the disease and organized (1894) the first laboratory for the study of tuberculosis. The sanatorium closed in 1954 for lack of patients, modern methods of early diagnosis and of treatment having drastically reduced incidence of the disease.
