I heard that he accidentally discovered penicillin.  Is that true?
user
It is true. Alexander Fleming worked at St. Mary’s Hospital in London, where he studied bacteria. He was observing a petri dish that had some Penicillium mold growing on it. During this time, a spore of a deadly bacteria known as staphylococcus developed on the petri dish.  Unfortunately, the staphylococcus bacteria introduced the growth of the Penicillium mold.
