Tuberculosis research. German physician Ernest von Bergmann (left, 1836-1907) supervising an injection for a tuberculosis patient. Bergmann worked with the German bacteriologist Robert Koch (1843-1910) on treatments for tuberculosis (TB). One such treatment was the injection of tuberculin, extracts of the tuberculosis bacterium. This was ineffective as a treatment, but was later developed as a diagnostic tool. Artwork from the seventh volume (first period of 1891) of the French popular science weekly 'La Science Illustree'.
