Sir Alexander Fleming (1881-1955)

Bacteriologist and discoverer of penicillin

Alexander Fleming studied medicine at St Mary’s Medical School in London and worked at that hospital’s Inoculation Department (later the Wright Fleming Institute) until he retired.  During the First World War he served as a captain in the Royal Army Medical Corps. He discovered penicillin in 1928 although its anti-bacterial properties were not fully exploited until the Second World War. It is one of the most important developments in modern medicine and he shared the Nobel Prize in 1945. He died suddenly in 1955 and his ashes are interred in St Paul’s Cathedral. He is commemorated in the Alexander Fleming Laboratory Museum and a collection of his papers are held by the British Library.
