Storyboard Text

  • What's happened here?
  • Sir Alexander Fleming (6 August 1881 – 11 March 1955) was a Scottish physician, microbiologist, and pharmacologist.  
  • His best-known discovery is the world's first antibiotic substance from the mould Penicillium notatum in 1928.
  • I should call this pencillin
  • AlexanderFleming came back from a vacation and realises that one of his petri dishes containing Staphylococcus aureus had been stopped in growth by a bacterium called Penicillium notatum.
  • Fleming grew the mould in a pure culture and found that it produced a substance that killed a number of disease-causing bacteria.
  • He identified the mould as being from the genus Penicillium, and, after some months of calling it "mould juice", Fleming decided to call this ‘antibiotic’ penicillin on 7 March 1929.
  • The laboratory in which Fleming discovered and tested penicillin is preserved as the Alexander Fleming Laboratory Museum in St. Mary's Hospital, Paddington.
