dec 1, 1880 - Germ Theory
Germ theory is a scientifically proven theorem that states many diseases are caused by microbes. It was originally thought of by Girolamo Fracastoro in 1546, however it was developed more during the golden age of microbiology. Before this, most societies believed in the Miasma theorem, where diseases were caused by bad air, also known as miasma. However, this was disproved in the late 19th century with the help of two scientists, Louis Pasteur and Robert Koch. Louis discovered that microbes cause disease, while Koch discovered a way to make sure it was created by a disease, called Koch's Postulates.
