This year (2022) marks the bicentenary birth (December 27, 1822) of Louis Pasteur. He has a global reputation. His contributions can be seen in our homes, in the "pasteurized" products derived from one of his discoveries and in disease prevention. It was in his discovery of gently heating beverages and food for what we today call pasteurization that he first said: “Man's first look at the universe discovers only variety, diversity, multiplicity of phenomena. Let this gaze be enlightened by science — by science which brings man closer to God — and simplicity and unity shine everywhere.” Louis Pasteur (Vallery-Radot, Life of Pasteur, 1902, English translation, p. 194, Monday, Nov. 11, 1867; 730 pm Orleans France)
