Alexander Fleming was one of the most well known world famous scientist. He was born in Scotland. He was the fourth child of his parents. LAter in 1906 he jained a medical school situated in London. He completed his graduation there in 1906. During world war 1 held on 1911-1918 in also assisted the hospital battlefield held in France. There he noticed that his soldier was dying only after a few years due to other diseases or septicemia  but not due to the war. When the war was over he started finding the medicines to get over these infections and heal the wounds. He got the medicineces and spays but were not so much effective the spray creates the wound more dangerous if it deep. Fleming got so much upset and decided to discover some more medicines.
He moved to his laboratory in 1928 and started the experiments. He creates many cultures of different bacteria in different dishes after sometimes he moticed the contaminatons appears in some dishes due to a fungus, he though that his effort was ruined and decided to discard the dishes but suddenly he noticed that in some places around the fungus the bacteria could not be able to develop in the dish.

He moved that fungus seperated in other dish and discovered that it is from the Penicillium group. In 1929, he made his discovery publicily. At that time few other doctors thought that about penicillin that it was an antibiotic could be a topical antiseptic, obtained through Penicillin fungus. Here Fleming was sure and confident that this antiseptic penicillin should also work within the body also. He also concluded through various experiments that the fungus also had a germ killing power yet after diluted it with a lot of water. Again in 1940 he tried to cultivate the penicillin but it was very difficult to develop, and also it was very difficult to get seperated the germ kill agent present in that fungus.
By the luck after sometime Ernst Chain who was a German Chemist had discovered a unique process of how to isolate the germ kill agent and concentrate it. One of the other scientist named Howard Florey also discovered the process to create a mass production of this fungus. During world war 1 this penicillin had cured many diseases and due to this discovery Florey and Chain also the Nobel Prize in 1945.
