Prize share: 1/1
After Robert Koch discovered that tuberculosis is caused by a bacterium, the hunt for a cure began. In 1939 Selman Waksman and colleagues began systematic studies of how microorganisms in soil affect tubercle bacteria. They found that their growth was impeded by another bacterium, Streptomyces grisues. In 1943 Selman Waksman's colleague, Albert Schatz, isolated streptomycin from this bacterium, which proved an effective medicine against tuberculosis.
