Introduction

Who played the most important role in the development of penicillin? Fleming rediscovered the properties of penicillin in 1928, he made extensive notes on his findings and later on published a paper/book on what he had discovered. His main findings showed that when various bacteria were added to dishes containing penicillin; some grew until they touched the penicillin mould and then stopped. Other bacteria wouldn't even go near it. Scientists later established that this was an antibacterial material, that is, that it was a micro organism capable of killing another micro organism. Few scientists showed interest in Fleming's findings at this time, apart from a man called Professor Rainstrick who studied at the London School of Hygiene and Tropical Medicine. ...read more.

It would also make the battle of preventing and fighting infection much easier. In a lot of the places where Fleming failed to succeed Chain and Florey provailed. They developed a method of growing penicillin. This proved to be costly and labourous at first, but it was a start. After producing enough pure penicillin Florey and Chain began to test its effectiveness on mice. The tests were successful and the two scientists were convinced that the drug would be able to cure many people who would otherwise die. Already Florey and Chain had taken the whole theorem of Penicillin having curative properties to a new level. They had already began to prove their research and the results were being seen as more and more convincing. ...read more.

Conclusion

Florey and Chain along with Flemming each received the Nobel Prize for the development of the penicillin drug in 1945. In my opinion each of the men played an active role in the developement of penicillin, however as you can see the more practical approach seems to have come from both Florey and Chain. Fleming has to be credited for rediscovering penicillin, however many critics would agree that this discovery was mainly due to chance. However, without that element of chance the development of the drug penicillin could never have happened. We owe Florey and Chain for their hard work and perseverence, and Fleming for his detailed accounts and research papers on penicillin and its antibiotic properties. Quite rightfully, each of them were awarded for their triumphs in 1945. ...read more.
