Alexander Fleming, Howard Florey and Ernst Chain


	Who?	What did they do?
	Alexander Fleming was a Scottish physician (1881 - 1955). Howard Florey was an Australian pathologist (1898 - 1968). Ernst Chain was a German biochemist (1906 - 1979).	Flemming found an antispetic that could kill most bacteria, however he wanted to find one for Staphylococcal. In 1928, he saw that on one of his experimental dishes a mould grew on the dish of Staphococcoli. Around the mould the bacteria had stopped growing. He had found Penicillium notatum. It produced a substance called Penicillin. However he could not prove his theory. Florey and Chain resumed his work nearly thirty years later. They made a project to produce a large amount of Penicillin. They couldn't get a grant from the British government so Florey went to America. They gave a grant when they joined the war.
