In this letter, Dr. Simon Flexner reported to Osler on tissue samples taken from leprous patients at Johns Hopkins Hospital. He gave a detailed analysis of the relation of the disease bacteria and the lesions, and commented on likely routes of transmission. Flexner (1863-1946), a pathologist and bacteriologist, became the first director of the Rockefeller Institute for Medical Research in 1901.
