Penicillin Mould, 1952, Recto


Case containing a colony of Penicillium notatum, the mould from which penicillin is derived.

Scottish biochemist Sir Alexander Fleming (1881-1955) inadvertently discovered the antibacterial properties of the mould at St. Mary's Hospital, London, in 1928, when he observed its ability to inhibit the growth of staphylococcus. For his discovery, Fleming shared the 1945 Nobel Prize with Howard Walter Florey and Ernst Boris Chain, who were responsible for the purification and first clinical trials of penicillin in 1941. Infections from casualties during World War II prompted the efficient production of this landmark antibiotic into the common drug we know today.

Fleming presented this case to the Student Representative Council when he was elected Rector of Edinburgh University (1951-1954).
