French chemist and microbiologist Louis Pasteur was born on December 27, 1822 in Dole, France. Pasteur is most known for his work in germ theory which led him to create the first vaccines for rabies and anthrax and for the invention of pasteurization. Pasteurization is a process by which you heat and cool liquids (like milk and wine) to prevent bacterial contamination.
Louis Pasteur is considered the father of microbiology and one of the three founders of Bacteriology. He suffered multiple strokes, from which he never fully recovered, and died on September 28, 1895 at the age of 72 in Marnes-la-Coquette, France. Pasteur’s breakthroughs in bacterial studies and vaccinations have saved countless lives all over the world.
