Louis Pasteur; the germ theory

Louis Pasteur, a renowned French scientist, is known for his germ theory. His interest in microorganisms began when a brewery sought his help to understand why their beer was spoiling. Pasteur discovered that specific microorganisms were responsible and developed pasteurization, a process of heating and cooling liquids to kill germs. This method gained popularity across industries facing similar issues, such as wine, vinegar, and milk. Pasteur's work on germ theory led him to enter a scientific competition organized by the French Academy of Science, where he competed against another scientist, Pouchet.
