Lister’s work was only made possible by Louis Pasteur’s discoveries.
- Louis Pasteur developed the pasteurization technique, which involves heating liquids and then letting them cool in order to kill bacteria, after learning that microbes were the cause of alcohol that had soured.
- His research on germ theory also inspired him and his team to develop the anthrax and rabies vaccines.
- Only Pasteur's discoveries made Lister's research possible. Infection was first thought to be caused by germs according to Pasteur.
- Lister developed the concepts of sterile surgery based on the "germ theory."
- Surgery was transformed into a sterile procedure thanks to Lister and Pasteur.
