Penicillin is one of the most important medicines in the world. It is a type of antibiotic that kills many harmful bacteria. Before penicillin, even a small infection could become deadly. People often died from diseases that we can easily cure today.

The discovery of penicillin happened by accident. A scientist named Alexander Fleming was studying bacteria in his laboratory. One day, he noticed something strange. A mold had grown on one of his experiment dishes, and around the mold, the bacteria had disappeared. Fleming realized that the mold was producing a substance that could kill bacteria. He called this substance penicillin.

However, making penicillin useful for patients was not easy. Many years passed before other scientists found a way to produce it in large amounts. During the Second World War, penicillin was used to treat wounded soldiers, saving countless lives. This discovery changed medicine forever. It opened the door to the development of many other antibiotics. Today, we still use penicillin to treat infections, and it remains one of the most important tools in modern healthcare.
