Fleming Museum

A compact, story-rich site at St Mary’s Hospital where Alexander Fleming observed a mould killing bacteria in 1928. A faithful lab reconstruction, a concise film and interpretive panels carry you from that bench-top accident to the antibiotic era.

Fleming’s Laboratory

Birthplace of penicillin

See the bench, Petri dishes and simple tools that turned a stray contaminant into the most consequential drug discovery of the 20th century.

Stand by the window bench and imagine noticing a clear ‘halo’ where bacteria failed to grow.

Discovery Film

From observation to therapy

A 10-minute overview links Fleming’s 1928 note to the Oxford group’s proof in 1940 and wartime scale-up.

Watch first, then re-enter the lab and spot items mentioned on screen.

Fleming published penicillin’s antibacterial action in 1929, but therapeutic success arrived a decade later with Florey and Chain’s Oxford experiments.
Early hospitals sometimes recovered scarce penicillin from patients’ urine and reused it during wartime shortages.
Industrial deep-tank fermentation—borrowed from food science—made mass penicillin possible by the mid-1940s.
