Alexander Fleming was born on 6 August 1881 in Lichfield, Staffordshire, England, UK. He was previously married to Ama Lia Koutsouri-Voureka and Sara Marion McElroy. He died on 11 March 1955 in London, England, UK.
He won the 1945 Nobel prize for Medicine and Physiology for his
discovery of penicillin. He shared it with Howard W. Florey and Ernst
B. Chain who helped develop it as an antibiotic.
[from his 1945 speech accepting the Nobel Prize in Physiology or Medicine] The time may come when penicillin can be bought by anyone in the shops. Then there is the danger that the ignorant man may easily under-dose himself and, by exposing his microbes to non-lethal quantities of the drug, make them resistant.
