Sir Alexander Fleming FRS FRSE FRCS^[2] (6 August 1881 \u2013 11 March 1955) was a Scottish physician and microbiologist, best known for discovering the world's first broadly effective antibiotic substance, which he named penicillin. His discovery in 1928 of what was later named benzylpenicillin (or penicillin G) from the mould Penicillium rubens has been described as the \"single greatest victory ever achieved over disease\".^[3]^[4] For this discovery, he shared the Nobel Prize in Physiology or Medicine in 1945 with Howard Florey and Ernst Chain.^[5]^[6]^[7]\n

He also discovered the enzyme lysozyme from his nasal discharge in 1922, and along with it a bacterium he named Micrococcus lysodeikticus, later renamed Micrococcus luteus.\n

Fleming was knighted for his scientific achievements in 1944.^[8] In 1999, he was named in Time magazine's list of the 100 Most Important People of the 20th century. In 2002, he was chosen in the BBC's television poll for determining the 100 Greatest Britons, and in 2009, he was also voted third \"greatest Scot\" in an opinion poll conducted by STV, behind only Robert Burns and William Wallace.\n
