Pasteur did. And he was pretty freaking smart. He developed the method of culturing organisms (in this case bacteria) using Petri plates and a nutritive substrate. We still use this today. . .like 200 years later. Anyway, he successfully linked the disease of anthrax with the microorganism that caused it. He took blood from healthy and diseased rats and compared the cultures. After identifying and isolating the one bacterial strain that was absent in the healthy and present in the disease, he injected that bacteria into a healthy rat. He proved the connection by again culturing blood from the newly diseased rat and finding the same bacteria. Very smart guy. This protocol is still used today.

"Louis Pasteur (December 27, 1822 – September 28, 1895) was a French chemist best known for his remarkable breakthroughs in microbiology. His experiments confirmed the germ theory of disease, also reducing mortality from puerperal fever (childbed), and he created the first vaccine for rabies. He is best known to the general public for showing how to stop milk and wine from going sour - this process came to be called pasteurization. He is regarded as one of the three main founders of bacteriology, together with Ferdinand Cohn and Robert Koch. He also made many discoveries in the field of chemistry, most notably the asymmetry of crystals."
