In the fields of observation, chance favors only the prepared mind
Born in Dole, Jura, France. My father was a tanner and decorated sergeant in Napoleon's army. Mediocre student as a boy. But at the Ecole Normale Superieure, I fell in love with crystallography. Discovered molecular chirality at 25. That led to fermentation, germ theory, pasteurization, and vaccines. I proved life does not arise spontaneously with swan-neck flask experiments. Developed vaccines for anthrax, cholera, and rabies. The rabies vaccine on young Joseph Meister in 1885 -- if it failed, the boy would die. It worked. Tip: The prepared mind comes from working 16-hour days, six days a week, for 40 years. There are no shortcuts.

Hands-on. We will ferment grape juice, observe yeast under the microscope, test for alcohol and acetic acid. This is how I started -- wine merchants of Lille asked why their fermentations kept failing...

Replicate my famous experiment. Two flasks of broth: one open, one with a swan-curved neck. The straight one spoils. The swan-neck stays clear for years. I still have flasks from the 1860s that are st...
