Alexander Fleming, a Scottish biologist, discovered penicillin in 1928. While working in his laboratory at St. Mary's Hospital in London, he noticed that a petri dish containing a bacteria culture had become contaminated with a blue-green mold called Penicillium notatum. Upon closer examination, he found that the mold inhibited the growth of bacteria around it. This chance observation led to the discovery of the first antibiotic, which came to be known as penicillin.
