Greatest Discoveries that have changed the world

A Penicillin

While the brilliant yet notoriously absent-minded biologist Sir Alexander Fleming was researching a strain of bacteria called staphylococci, he noticed that one of the glass culture dishes he had accidentally left out had become contaminated with a fungus, and so threw it away. Soon he observed that the staphylococcus bacteria seemed unable to grow in the area surrounding the fungal mould. Fleming did not even hold out much hope for his discovery, it was not until 1945 after further research by several other scientists that penicillin was able to be produced on an industrial scale, changing the way doctors treated bacterial infections forever. Penicillin antibiotics are historically significant because they are the first drugs that were effective against many previously serious diseases.
