Contributions
- Louis Pasteur is one of the three main founders of
bacteriology, along with
Ferdinand Cohn and
Robert Koch.
He is also regarded as the "father of microbiology".
- Invented Pasteurization,
a technique used for treating milk and wine to stop bacterial contamination.
- Theses on fermentation and germ theory of diseases. He proved that fermentation
happens because of living organisms.
- Immunology and vaccination:
Discover vaccines for
chicken cholera,
rabies,
and anthrax.
- He discovered the existence of Molecular Asymmetry.
Controversies
- Fermentation by living organisms were said to had been studied
by Charles Cagniard-Latour, Friedrich Traugott Kützing and Theodor Schwann in the
1930s, before Louis Pasteur findings.
- Publicization of Pasteur's laboratory notes reveals that his anthrax vaccines
use a large amount of work from
Jean Joseph Henri Toussaint, who
Pasteur did not mention in his final work.
- Experimental ethics: Many of Pasteur's works and procedures were
under critism. He practiced medical experienments even though he did not have
a medical license. Pasteur's procedures were also under questions because he
always kept them secret. It is later revealed that Pasture did not use proper
pre-clinical trials on animals before testing the rabies vaccines a human.
