Developed a way to stain different bacteria using coloured dyes which made it easier to single out and study each type of bacteria
Discovered cholera microbe
Made it easier for future scientists to study bacteria by growing them in a petri dish and using microscopes.
Louis Pasteur - famous for germ theory
French scientist who worked in France for the second half of the 19th Century.
Asked by the French government to investigate why wine was going bad. He used a powerful microscope to observe microbes in the wine and proved that it could be kept fresh as long as it was not exposed to air.
Proved that microbes did not grow from within the liquid but only published his ideas until 1878.
Edwin Chadwick
Lawyer, but also published studies into health and social problems in towns and cities.
Proved that people in larger cities had shorter lives than the rest of the population, and that the main reason was the filthy living conditions.
