Alexander Fleming, Howard Florey and Ernst Chain


	Who?	What did they do?
	Fleming was a Scottish physician (1981- 1955). Florey was an Australian pathologist (1898 -1968). Ernst Chain was a German biochemist (1906 -1979).	Fleming saw hundreds of soldiers die during World War 1 and noticed that wounds were often infected by Staphylococcal. He searched for a cure and found an antiseptic that only killed certain bacteria. When he was clearing away some dishes he noticed a mould had grown and the Staphylococci around it had stopped growing. This was Penicillium notatum. It produced a substance called Penicillin. However, he could not prove his discovery. Florey and Chain developed Fleming's theory. They set out to start a mass production of Penicillin.

Teamwork - Florey and Chain worked together using Flemings work. Communication - They used Flemings work and helped each other.
