Anton van Leeuwenhoek
invented the microscope
was able to create diagrams that clearly showed the three major
shapes of bacteria (bacilli, cocci, spiral)
Lazzaro Spallanzani
conducted experiments to dispute the inspired Louis Pasteur and John Tyndall to continue experimentation
microlevel theory of spontaneous
that eventually disproved the doctrine of spontaneous generation
generation
once and for all
Edward Jenner
first experiemented with cowpox as
an way to prevent smallpox
led to some 6000 people receiving inoculations to prevent smallpox inspired Pasteur's development of vaccinations
Louis Pasteur
developed the germ theory of
fermentation
inspired the developmnet of the germ theory of disease - specific
vaccines were made from a weakened or atenuated pathogens - due
to his work on bacteria and vaccines, he is known as the "father of
bateriology and immunology"
Ignaz Philipp Semmelweis
noted that illness could be spread to
other patients by the treating
physicians
Developed a hypothesis for the first real safety precaustions in a
hospital. All hands had to be carefully washed before a patient was
examined. His work inspired Joseph Lister to expand on this idea of
a clean environment to prevent infection.
Joseph Lister
prevented the growth of
microorganisms by using carbolic
acid in the washing or disinfection of
hands and surgical tools
lowered fatality rate of his surgical patients and introducted aseptic
technique to medical facilities
Robert Koch
developed an elaborate technique of
isolating and identifying specific
pathogens that cause specific
diseases
established rules that identified specific organisms as the cause of a
specific disease - 4 rules or postulates
