In his youth, Pasteur did not especially excel as a student. His interests inclined toward art rather than science, and he did display exceptional skill at drawing and painting. But in light of career considerations (his father wanted him to be a scholar), Pasteur abandoned art for science and so applied to the prestigious École Normale Supérieure ...
Pasteur’s investigations of the growth of microorganisms in fermentation collided with another prominent scientific issue: the possibility of spontaneous generation of life. Popular opinion even among many scientists held that microbial life self-generated under the proper conditions (spoiled meat, for example). Demonstrations by the 17th century I...
As geniuses go, Pasteur was the opposite of Einstein. To get inspiration for his theories, Einstein imagined riding aside a light beam or daydreamed about falling off a ladder. Pasteur stuck to experiments. He typically initiated his experiments with a suspected result in mind, but he was scrupulous in verifying the conclusions he drew from them. P...
Learn how Pasteur invented pasteurization, established the germ theory of disease, and transformed public health with his scientific discoveries. Explore his life, achievements, controversies, and legacy in this article by Tom Siegfried.
Louis Pasteur, France Louis Pasteur's spontaneous generation experiment illustrates that liquid nutrients are spoiled by particles in the air rather than the air itself. These results of these experiments supported the germ theory of disease.

Jul 24, 2023 · The germs involved included bacteria, viruses, fungi, protozoa, and prions. Louis Pasteur (1822-1895), a French chemist and microbiologist, and Robert Koch (1843-1910), a German physician and microbiologist, are credited with the discovery of the germ theory in the 1860s-1880s.
Learn about the history and development of germ theory, which states that specific microbes cause specific diseases. Explore the contributions of Louis Pasteur and other scientists, the public awareness campaigns, and the challenges of treatment.
Learn how Pasteur's discovery of bacteria and pasteurisation challenged the theory of spontaneous generation and led to changes in medicine in 19th-century Britain. Find out how Lister applied Pasteur's ideas to surgery and how microscopes helped to identify bacteria.
