My DH's great grandfather was a famous scientist....Dr. Robert Koch, a German physician and scientist, presented his discovery of Mycobacterium tuberculosis, the bacterium that causes tuberculosis (TB), on the evening of March 24, 1882. He became known as "The Father of Bacteriology." He was presented with the Nobel Prize in Physiology or Medicine in 1905 "for his investigations and discoveries in relation to tuberculosis."
