Sir Alexander Fleming (6 August 1881 – 11 March 1955) was a Scottish biologist and pharmacologist. Fleming published many articles on bacteriology, immunology and chemotherapy. His best-known achievements are the discovery of the enzyme lysozyme in 1923 and the antibiotic substance penicillin from the fungus Penicillium notatum in 1928, for which he shared the Nobel Prize in Physiology or Medicine in 1945 with Howard Walter Florey and Ernst Boris Chain.[1]

In 1999, Time Magazine named Fleming one of the 100 Most Important People of the 20th Century for his discovery of penicillin, and stated; "It was a discovery that would change the course of history. The active ingredient in that mold, which Fleming named penicillin, turned out to be an infection-fighting agent of enormous potency. When it was finally recognized for what it was—the most efficacious life-saving drug in the world—penicillin would alter forever the treatment of bacterial infections. By the middle of the century, Fleming's discovery had spawned a huge pharmaceutical industry, churning out synthetic penicillins that would conquer some of mankind's most ancient scourges, including syphilis, gangrene and tuberculosis".[2]
Early life

St.Mary's Hospital, Paddington, London.Fleming was born on 6 August 1881 at Lochfield, a farm near Darvel in East Ayrshire, Scotland. He was the third of the four children of Hugh Fleming (1816–1888) from his second marriage to Grace Stirling Morton (1848–1928), the daughter of a neighbouring farmer. Hugh Fleming had four surviving children from his first marriage. He was 59 at the time of his second marriage, and died when Alexander (known as Alec) was seven.


Fleming went to Louden Moor School and Darvel School, and then for two years to Kilmarnock Academy. After working in a shipping office for four years, the twenty-year-old Fleming inherited some money from an uncle, John Fleming. His older brother, Tom, was already a physician and suggested to his younger sibling that he follow the same career, and so in 1901, the younger Alexander enrolled at St Mary's Hospital, Paddington, London. He qualified for the school with distinction in 1906 and had the option of becoming a surgeon.
