Alexander Fleming

Alexander Fleming, who had been famous for his discovery of the antibiotic substance penicillin, was born on August 6th, 1881 in the Scottish city of Lochfield, near Darvel. He studied medicine at St Mary's Hospital Medical School in Paddington because his elder brother suggested him to study it.

So, after being working at St Mary’s Hospital of London until the World War I, where he worked in the microbiology and the vaccines and showed interest about new treatments about it, he was a doctor during the war and he stayed impressed about the huge number of soldiers who died because of infections. At that point, he started to investigate about the bacteria and ten years later of the finish of the war, Fleming discovered accidentally the Penicillin.

Fleming reported his discovery of penicillin in the British Journal of Experimental Pathology in 1929. Unfortunately, until the World War II, the Penicillin hadn’t caught the recognition and the importance that it really had. What is more, Fleming could improve the antibiotic with the help of two chemicals, Ernst Boris Chain and Howard Walter Florey. His discovery of penicillin had changed the world of modern medicine by introducing the age of useful antibiotics; penicillin has saved, and is still saving, millions of people around the world.
