Robert Koch’s discovery of the tubercle bacillus in 1882 was a major event in the history of medicine, a turning point in our understanding and conquest of that deadly disease which had plagued mankind for millenia. After centuries of speculation as to the possible infectious nature of tuberculosis, Koch proved conclusively that the cause of the disease was infection by a specific micro-organism which he isolated. In tuberculosis, both seed and soil play their part, but without the seed — the tubercle bacillus — there is no disease.
