1822 - Louis Pasteur was born on the 27th of December in Jura, France.

1854 - He was named Dean of the new College of Science in Lille.

 

1856 - He became Administrator and Director of Scientific Studies of the École Normale Supérieure.

1895 - He won the Leeuwenhoek medal which is granted to the most significant contribution to microbiology during the preceding decade.
