Contributions

  1. 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".
  2. Invented Pasteurization, a technique used for treating milk and wine to stop bacterial contamination.
  3. Theses on fermentation and germ theory of diseases. He proved that fermentation happens because of living organisms.
  4. Immunology and vaccination: Discover vaccines for chicken cholera, rabies, and anthrax.
  5. 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.
