Notice to the world of perhaps the greatest single medical innovation of the 20th century. Fleming's discovery of penicillin was somewhat by chance, as related in Printing and the Mind of man, while he was seeking a more powerful antiseptic - "in the course of this research Fleming noticed the accidental contamination of a culture plate of staphylococci by a mould which had floated through the window. The colonies of this common pus-forming bacterium adjacent to the mould appeared to be destroyed by it..." It was not until ten years later that practical application for the drug was made, by Ernst Chain and Howard Foley, just in time for the later stages of the Second World War. PMM 420.
