Louis Pasteur

Louis Pasteur (French: Louis Pasteur, French: [lwi pastœʁ]; December 27, 1822 - September 28, 1895) was a French biologist, chemist, and one of the founders of the fields of microbiology, immunology, and fermentation technology. He is famous for using the theory of panspermia to deny the theory of spontaneous generation (theory of spontaneous generation), advocating the germ theory of disease (the theory of panspermia), and inventing vaccination methods and pasteurization. He is the first scientist to create vaccines for rabies and anthrax. He is praised by the world as "the most flawless person who has entered the kingdom of science." Together with Ferdinand Cohen and Robert Koch, he pioneered bacteriology and is considered one of the founders of microbiology. He is often called the "Father of Microbiology". In 2005, French National Radio 2 held a selection event for the "Greatest Frenchman", and Pasteur ranked second, second only to Charles de Gaulle.
