Datebook: April 20 - Louis Pasteur Develops Pasteurization 150 Years Ago

Apr 20, 2012

Louis Pasteur was a French chemist and microbiologist known for his remarkable breakthroughs in vaccinating rabies and anthrax, and for reducing mortality from fevers. He may be best remembered for the discovery that is his namesake: pasteurization, a method to stop milk, beer, and wine from causing sickness. His research showed that the growth of micro-organisms were responsible for spoiling beverages. So he invented a process in which liquids were heated to kill most the bacteria already present within. He, along with Physiologist Claude Bernard, completed the  first test on April 20, 1862. Because of his study in germs, Pasteur encouraged doctors to sanitize their hands and equipment before surgery, a practice relatively unheard of at the time.
