  • Alexander Fleming. "Alexander Fleming, a Scottish bacteriologist in London, discovered penicillin by mistake when he was trying to study staphylococci bacteria in 1928. He was running experiments with the bacteria in his laboratory at London's St. Mary's Hospital, and set a laboratory dish containing the bacteria near an open window. Upon returning to the experiment, he found that some mold blown in through the open window onto the dish, contaminating the bacteria. Instead of throwing away his spoiled experiment, Fleming looked closely at it under his microscope. Surprisingly, he saw not only the mold growing on the staphylococci bacteria, but a clear zone around the mold. The Penicillium mold, the precursor to penicillin, was dissolving the deadly staphylococci bacteria." Source and more: http://www.wisegeek.com/how-was-penicillin-discovered-and-developed.htm
