For his discovery of the tuberculosis bacilli, Robert Koch received the Nobel Prize in Medicine in 1905. Like many scientists of his time, Robert Koch also researched cholera.
Who Cured Tuberculosis?
Schuchart, Sabine. Robert Koch received the Nobel Prize for Medicine in 1905 for his research into the tubercle bacterium. Contrary to what he had hoped, however, he did not succeed in developing an effective vaccine against the dangerous infectious disease.
When was tuberculosis cured?
At this low point, in 1856, Hermann Brehmer (1826 – 1899) declared tuberculosis to be curable. He believed in so-called “immune places”, areas where the phthisis cannot occur and where it must therefore heal. He founded the “Görbersdorf” sanatorium, which was opened in 1871.
