Who they were
Born in Adelaide, South Australia, Florey led pathology at the University of Oxford, where he built a team to study penicillin.
What they did
Penicillin had been discovered by Alexander Fleming; Florey, Ernst Chain, and others purified it and proved it could cure infections as a drug — saving many lives in the Second World War.
Legacy
In 1945 he shared the Nobel Prize with Fleming and Chain. Florey is regarded as one of the most influential scientists Australia has produced.
