In 1928 Alexander Fleming left a culture plate smeared with staphylococcus bacteria on his lab bench while he went on a two-week holiday. When he returned, he noticed a clear halo surrounding the bacteria. Unknown to him, a spore called penicillium notatum had drifted in from a mycology lab one floor below. Later, as the temperature in the room rose, the bacteria grew, covering the entire plate — except for the area surrounding the penicillium. Seeing that halo was Fleming's "Eureka!" moment. He deduced that the mold must have released a substance that inhibited the growth of the bacteria.
In 1939 a team of scientists at Oxford were able to make penicillin widely available. Pneumonia, syphilis, gonorrhea, diphtheria, scarlet fever, and many wound and childbirth infections suddenly became treatable.
