French chemist and biologist whose discovery that fermentation is caused by microorganisms resulted in the process of pasteurization (1822-1895)

Pasteur is a station of the Paris Métro, named after the Boulevard Pasteur. Louis Pasteur (1822-1895) was a French microbiologist and chemist. He is best known for demonstrating how to prevent milk and wine from going sour, which came to be called pasteurization.

Pasteur is a large lunar crater belonging to the category termed a walled plain. It lies on the far side of the Moon as seen from the Earth, just beyond the eastern limb. The vicinity of this crater is occasionally brought into view of the Earth due to librations, although not much detail can be seen.
