Who discovered penicillin?

Alexander Fleming discovered penicillin. In 1928, while working at St. Mary’s Hospital in London, he noticed that a mold called Penicillium notatum inhibited bacterial growth in a culture plate. This serendipitous observation led to the recognition of penicillin’s antibiotic properties, revolutionizing medicine and earning Fleming the Nobel Prize in Physiology or Medicine in 1945. His discovery marked a pivotal moment in the history of medicine, providing a potent weapon against bacterial infections and saving countless lives. Penicillin’s introduction transformed the treatment of infectious diseases, significantly reducing mortality rates associated with bacterial infections and laying the groundwork for the development of other antibiotics. Fleming’s contribution to medical science remains unparalleled, and his discovery continues to have a profound impact on healthcare worldwide, serving as a testament to the importance of serendipity and curiosity-driven research in scientific breakthroughs.
