French chemist and microbiologist Louis Pasteur was born December 27, 1822 in Dole, France.

His immense legacy can even be seen in our homes, in the “pasteurized” products derived from one of his discoveries. And it was Pasteur who laid the scientific foundations for the principles of hygiene, which took on such importance during the pandemic. Louis Pasteur himself always avoided shaking hands, and if he ever made an exception he would wash them immediately. While Pasteur is famous for his rabies vaccine – which earned him the title “benefactor of humanity” –, the full breadth of his scientific achievements is less well known, despite the fact that they continue to have an impact on our daily lives and on today’s research and medicine.
