Although highly controversial when first proposed, germ theory was validated in the late 19th century and is now a fundamental part of modern medicine and clinical microbiology, leading to such important innovations as antibiotics and hygienic practices. The French chemist and microbiologist Louis Pasteur , the English surgeon Joseph Lister , and the German physician Robert Koch are given much of the credit for development and acceptance of the theory. Pasteur proposed that “a growing living organism was responsible for the spoilage”; thus the name germ actually originated from germination- which indicates that the growth of the microbe in the food (wine and beer) was responsible for the spoilage.
