Alexander Fleming was born in Ayrshire on the 6th August 1881 to two farmers. He attended the Louden Moor School, the Darvel School, Kilmarnock Academy throughout his childhood, eventually enrolling in Regent Street Polytechnic in London marking the conclusion of his basic education.
Fleming studied at St Mary's Hospital Medical School in the University of London, going on to win the medal for top medical student in 1908. He was briefly dispatched in the line of duty but soon returned to St Mary's thereafter.
Fleming was a member of the Territorial Army and served in the Army Medical Corps, gaining first hand experience of the field as a bacteriologist studying wound infections.
In 1928, Fleming happened upon a discovery that forever changed medicine. After leaving a set of culture dishes out in the sun he noticed a bacteria-free circle created by and surrounding the mould. After much research he dubbed the active substance "penicillin" but was forced to leave his discoveries be, finding no further path to be taken.
Fleming's work was continued by two scientists who further developed penicillin and spread its use as a drug to eventually be mass produced. For their collective works the three were awarded the Nobel Prize in medicine in 1945.
Alexander Fleming died on the 11th March, 1955. It was a heart attack that took him in his London home. He was buried in St Paul's Cathedral.
