Alexander Fleming, Howard Florey and Ernst Chain shared the 1945 Nobel Prize in Physiology or Medicine for the discovery and development of penicillin. After the end of the war in 1945, penicillin became widely available. Dorothy Hodgkin determined its chemical structure, for which she received the Nobel Prize in Chemistry in 1964.
His discovery in 1928 of what was later named benzylpenicillin (or penicillin G) from the mould Penicillium rubens has been described as the "single greatest victory ever achieved over disease". [ 3 ] [ 4 ] For this discovery, he shared the Nobel Prize in Physiology or Medicine in 1945 with Howard Florey and Ernst Chain .
The source of the fungal contamination in Fleming's experiment remained a speculation for several decades. Fleming suggested in 1945 that the fungal spores came through the window facing Praed Street. This story was regarded as a fact and was popularised in literature, [23] starting with George Lacken's 1945 book The Story of Penicillin. [5]
The 1945 Nobel Prize in Physiology or Medicine was shared by Chain, Fleming, and Florey. ... (as first evidenced by the discovery of penicillin in 1928 [46]).
Howard Walter Florey, Baron Florey, OM FRS FRCP (/ ˈ f l ɔːr i /; 24 September 1898 – 21 February 1968) was an Australian pharmacologist and pathologist who shared the Nobel Prize in Physiology or Medicine in 1945 with Ernst Chain and Sir Alexander Fleming for his role in the development of penicillin.

In 1945, Hodgkin and her colleagues, including biochemist Barbara Low, solved the structure of penicillin, demonstrating, contrary to scientific opinion at the time, that it contains a β-lactam ring. The work was not published until 1949. [37] [nb 1]
Chain and Florey discovered how to isolate and concentrate the germ-killing agent in penicillin. For this research, Chain, Florey, and Fleming received the Nobel Prize in 1945. Along with Edward Abraham he was also involved in theorising the beta-lactam structure of penicillin in 1942, [ 17 ] which was confirmed by X-ray crystallography done by ...
