Louis Pasteur

Louis Pasteur was born to Jean-Joseph and Jeanne-Étiennette Pasteur in Dole, France. His father was a tanner, and his mother was a deeply religious woman who instilled a strong work ethic in Louis.

Pasteur begins his secondary education at the Royal College of Besançon, where he shows a keen interest in science and drawing. His talent in these areas is recognized by his teachers.

Pasteur graduates from the École Normale Supérieure in Paris with a degree in chemistry. He becomes a teacher at the same institution, where he begins his research in crystallography and organic chemistry.

Pasteur is appointed Professor of Chemistry at the University of Strasbourg. He continues his research on the structure of crystals and the properties of tartaric acid, which leads to significant discoveries in the field of stereochemistry.

Pasteur is appointed Dean of the Faculty of Sciences at the University of Lille. He focuses on fermentation and the role of microorganisms, which will later lead to his groundbreaking work in microbiology.

Pasteur discovers that certain crystal structures can exist in two forms that are mirror images of each other, a phenomenon known as molecular asymmetry. This work has profound implications for the field of organic chemistry.

Pasteur conducts experiments that disprove the theory of spontaneous generation, demonstrating that microorganisms come from pre-existing microorganisms. This work is a significant milestone in the development of microbiology.

In response to the wine industry's problems with spoilage, Pasteur develops the process of pasteurization, which involves heating liquids to kill harmful microorganisms. This process revolutionizes the food industry.

Pasteur and his team develop the first successful vaccine against rabies, which is tested on humans in 1885. This achievement cements his reputation as a pioneer in medical science and public health.

The Pasteur Institute is founded in Paris, with Pasteur as its director. The institute becomes a leading center for medical research and the development of vaccines and treatments for infectious diseases.

Louis Pasteur dies at his home in Marnes-la-Coquette, France. He is remembered as one of the most influential scientists in history, whose work laid the foundation for modern microbiology and immunology.
