On September 28, 1928, Alexander Fleming accidentally discovered penicillin. He was investigating the properties of staphylococcus bacteria and, after returning from a vacation, discovered that one culture had been contaminated by a mold, and the bacteria surrounding the mould had been killed. Fleming named the mold’s secretions penicillin, and discovered that it was effective against a number of diseases. He was awarded the Nobel prize in 1945 for his discovery.
