Louis Pasteur’s devotion to truth transformed what we know about health and disease

Louis Pasteur demonstrated, more dramatically than any other scientist, the benefit of science for humankind.

Great scientists become immortalized in various ways.
Some through names for obscure units of measurement (à la Hertz, Faraday and Curie). Others in elements on the periodic table (Mendeleev, Seaborg, Bohr, among many others). A few become household names symbolizing genius — like Newton in centuries past and nowadays, Einstein. But only one has been honored on millions and millions of cartons of milk: the French chemist, biologist and evangelist for experimental science Louis Pasteur.
