Sample of penicillin mould presented by Alexander Fleming to Douglas Macleod in 1935. The discovery of penicillin was one of the most important scientific discoveries in the history of medicine. Ancient societies used moulds to treat infections and in the following centuries many people observed the inhibition of bacterial growth by moulds.
Commemorative plaque marking Fleming's discovery of penicillin at St Mary's Hospital, London. The laboratory in which Fleming discovered and tested penicillin is preserved as the Alexander Fleming Laboratory Museum in St. Mary's Hospital, Paddington. The source of the fungal contaminant was established in 1966 as coming from La Touche's room ...
Original – Microbiologist Alexander Fleming in his laboratory, 1943 Reason Alexander Fleming discovered penicillin in 1928. This photo shows him in his laboratory around 1943, a few years before receiving the Nobel Prize in medicine in 1945 along with Florey and Chain who established penicillin's therapeutic application. The photo shows him ...
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.
Penicillin was discovered in 1928 by Scottish scientist Alexander Fleming as a crude extract of P. rubens. [6] Fleming's student Cecil George Paine was the first to successfully use penicillin to treat eye infection (neonatal conjunctivitis) in 1930.
Penicillium rubens is a species of fungus in the genus Penicillium and was the first species known to produce the antibiotic penicillin. It was first described by Philibert Melchior Joseph Ehi Biourge in 1923. For the discovery of penicillin from this species Alexander Fleming shared the Nobel Prize in Physiology or Medicine in 1945.

Electrocardiography: Alexander Muirhead (1869) [144] [145] Discovery of Staphylococcus: Sir Alexander Ogston (1880) [146] Discovering insulin: John Macleod (1876–1935) with others [11] The discovery led him to be awarded the 1923 Nobel prize in Medicine. [147] Penicillin: Sir Alexander Fleming (1881–1955) [10]
Molecular phylogeny has established that Alexander Fleming's first discovered penicillin producing strain is of a distinct species, P. rubens, and not of P. notatum. [4] [5] It has rarely been reported as a cause of human disease. [6] It is the source of several β-lactam antibiotics, most significantly penicillin.
