This first experiment became the foundation of a new area in organic chemistrycalled stereochemistry. This was a revolutionary idea at the time, as it also corroborated a theory that Pasteur had been developing: that symmetry is the key to life and that all life processes stem from the precise...

Louis Pasteur discovered that microbes were responsible for souring alcohol and came up with the process of pasteurization, where bacteria are destroyed by heating beverages and then allowing them to cool. His work in germ theory also led him and his team to create vaccinations for anthrax and ra...
Pasteur went on to try this on cows who were suffering from anthrax poisoning. Once again his experiment was successful. His next set of experiments was on pigs and dogs. All this research helped him develop a vaccine for rabies. With this vaccine, he saved a seven-year-old’s life in ...
On June 13, 1881, less than 2 weeks after his celebrated success at Pouilly-le-Fort, Pasteur presented his account of the experiment before the Academie des Sciences (Pasteur et al., 1881a): The Academie ought to realize that we did not draw up such a (experimental) program without ha...
In May 1881, in the French village of Pouilly-le-Fort, Pasteur launched a “bold public demonstration” of the vaccine in an experiment involving 50 sheep. When it was successful, he returned in June “to bask in the applause” from an appreciative crowd of reporters and dignitaries. “It...

Pasteur was still a student when he made his first discovery with an experiment in crystallography. He noted that the organic compound, when synthesised in the laboratory, was optically inactive, or unable to rotate the plane of polarised light. And yet, natural tartrate, an acid formed in gra...

In the mid-nineteenth century, French chemist and microbiologist Louis Pasteur (1822-1895) was developing his germ theory. The theory held that specific microorganisms cause specific diseases. Pasteur's first experience with microorganisms as the cause of disease occurred when he was investigating a ...
