A French chemist who discovered that heat could kill bacteria that spoiled liquids, including milk, is who?

Heat treatment of liquids to kill microbes is tied to the discovery by Louis Pasteur. This French chemist showed that heating beverages could destroy the bacteria causing spoilage, which led to pasteurization—a process used to make milk and other liquids safer by reducing microbial load. He also helped establish germ theory, showing that microorganisms are responsible for fermentation, spoilage, and disease. The other names don’t fit this description: the Hippocratic Oath is a physician’s ethical pledge, Joseph Lister is known for antiseptic surgery, and Galen is an ancient physician.
