1822-1895 – The Process of Pasteurization is Developed by Louis Pasteur

French chemist and biologist Louis Pasteur, considered one of the fathers of microbiology, helped prove that infectious diseases and food-borne illnesses were caused by germs, known as the “germ theory.”

Pasteur’s research demonstrated that harmful microbes in milk and wine caused sickness, and he invented a process – now called “pasteurization” – whereby the liquids were rapidly heated and cooled to kill most of the organisms.
