What happened at the Discovery of penicillin

Alexander Fleming returned from vacation to his laboratory at St Mary's Hospital, London, and noticed that a stray mold, Penicillium notatum, had contaminated a petri dish of Staphylococcus bacteria and killed the surrounding colonies. He identified the active substance as penicillin and published his findings in 1929, though its therapeutic potential was not immediately pursued. Over a decade later, in the late 1930s and early 1940s, scientists Howard Florey and Ernst Chain developed methods to produce and purify penicillin for medical use, enabling mass production during World War II. This discovery launched the era of antibiotics, transforming the treatment of bacterial infections and saving countless lives worldwide.
