Who discovered penicillin?

Penicillin was discovered by Sir Alexander Fleming in 1928. He noticed that a mold called Penicillium notatum inhibited the growth of bacteria in one of his petri dishes. This accidental observation led to the development of penicillin, the world’s first true antibiotic. Penicillin revolutionized medicine by effectively treating bacterial infections that were once deadly, such as pneumonia, meningitis, and wound infections. During World War II, it saved countless lives and became widely produced. Fleming’s discovery paved the way for modern antibiotics, transforming healthcare and contributing to the significant decline in mortality from infectious diseases across the globe.
