Many truly amazing and inspiring things came out of Alexander's discovery of penicillin. Before penicillin, people around the world would routinely die from infections of the simplest wounds. After penicillin was created, it was shown to save many lives, so the antibiotic started being used in wars, specifically World War 2. It became a revolutionary medicine in wars and for regular people with illnesses as well. Once the world realized how much of an impact penicillin was having on society, the U.S. government and pharmaceutical companies embraced the idea of the new antibiotic. Penicillin also made the job of a doctor much more simple. Instead of trying to find out ways to prevent the spread of bad bacterias, doctors could now kill off bacteria immediatley.

Sir Alexander Fleming's creation of penicillin has impacted the world of science and medicine.
