100 Greatest Discoveries - Top Ten [2/7]

[09.2] Microorganisms (1674): Microscope lens grinder Anton Van Leeuwenhoek accidentally discovers microorganisms in a drop of water. Using his own microscopes, he observes sperm, bacteria and red blood cells. His observations lay the foundation for the sciences of bacteriology and microbiology.

[08] Penicillin (1920s--1930s): Alexander Fleming discovers penicillin, then Howard Florey and Boris Chain isolate and purify the compound, producing the first antibiotic. Fleming's discovery comes completely by accident when he notices that mold has killed a bacteria sample in a petri dish that is languishing under a pile in his lab's sink. Fleming isolates a sample of the mold and identifies it as Penicillium notatum. With controlled experimentation, Florey and Chain later find the compound cures mice with bacterial infections.

[07.1] Germ Theory (1800s): French chemist Louis Pasteur finds that certain microbes are disease-causing agents. At the time, the origin of diseases such as cholera, anthrax and rabies is a mystery. Pasteur formulates a germ theory, postulating that these diseases and many others are caused by bacteria. Pasteur is called the "father of bacteriology" because his work leads to a new branch of scientific study.
