  • Robert Koch
    • successfully identified the different germs
    • published his ideas on the methods that could be used to identify disease-causing microbes
      • the microbe is present in every case of the disease
      • once taken from the body, the microbe can be re-produced into a pure culture
      • the disease can be reproduced in test animals using that culture
      • the microbe can then be taken out of the test animals and used to start a fresh culture
    • 1882 -     Koch discovered the bacteria that caused tuberculosis
    • 1883 -        he discovered the bacteria that caused cholera
      • 1884 -  proved that it was spread in water supplies
    • made it easier for future scientists to study bacteria by developing a new method of studying them, using agar in a petri dish
    • Koch's research inspired other scientists
    • received the Nobel Prize for Medicine in 1905
    • Koch's influence in Britain
      • by developing the dye to stain microbes, Koch made it easy to see microbes
      • before Koch's discoveries, symptoms were studied. Afterwards, diseases themselves were studied by British scientists
      • Koch's new methods of growing microbes made it easier for other scientists to study specific diseases
      • the British government did not listen to Koch's discoveries in the short term
      • Koch inspires other to look for microbes responsible for other diseases
