Louis Pasteur’s work

Every discovery opened a new field of investigation leading to further breakthroughs. Louis Pasteur’s life’s work can be divided into three main parts. Chemistry and the observation of crystals led him to study fermentation. And this led to his disproving of the spontaneous generation theory, a key discovery which opened the doors to microbiology and vaccination.

 

The early years 1847-1862

In 1847 Louis Pasteur, a young chemist freshly graduated from the prestigious Ecole normale supérieure, attempted to understand why two seemingly identical chemical substances affect polarized light differently.

 

The middle years 1862-1877

Louis Pasteur’s work raised a new set of research questions, such as "Where do fermentation agents come from ?" and " Do they originate from germs similar to themselves or do they appear spontaneously as explained by the spontaneous generation theory? "

 

The final years 1877-1887

Between the age of 55 and 65 Louis Pasteur developed microbiology, applying it to medicine and surgery. Having established that diseases were caused by microorganisms, he then sought to identify and find a means of fighting them. His finest accomplishment was rabies.
