Biography
Sir Alexander Fleming (6 August 1881 – 11 March 1955) was a Scottish doctor, bacteriologist, and pharmacologist. His discovery of penicillin changed the practice of medicine in the 20th century. Born in Lochfield, Ayrshire, Scotland, Fleming studied medicine at St Mary's Hospital Medical School and Imperial College London, becoming a notable figure in microbiology. He spent most of his career at St Mary's Hospital, where his careful and curious approach to lab work led to some of the most important discoveries in medical history.
Before Fame
Fleming was born on August 6, 1881, at Lochfield Farm near Darvel in Ayrshire, Scotland. He was the seventh of eight children in a farming family. After finishing his early education at Kilmarnock Academy, he moved to London and worked in a shipping office. A small inheritance enabled him to study medicine. He enrolled at St Mary's Hospital Medical School and became a qualified doctor in 1906. Afterward, he joined the Inoculation Department under Sir Almroth Wright, a leader in vaccine therapy. During World War One, his research on wound infections and the limitations of antiseptics made him believe that the body's natural defenses were more important than harsh chemicals in fighting bacterial diseases.
Key Achievements
- Discovery of penicillin from the mould Penicillium rubens in 1928, described as the single greatest victory ever achieved over infectious disease
- Discovery of the enzyme lysozyme in 1922, an important component of the body's natural antibacterial defenses
- Awarded the Nobel Prize in Physiology or Medicine in 1945, shared with Howard Florey and Ernst Chain
- Knighted for scientific achievement in 1944, becoming Sir Alexander Fleming
- Elected a Fellow of the Royal Society in 1943, in recognition of his contributions to microbiology and medicine
Did You Know?
- 01.Fleming discovered the enzyme lysozyme in 1922 after observing that his own nasal mucus could dissolve certain bacteria on a culture plate, leading him to identify both the enzyme and a new bacterium he named Micrococcus lysodeikticus.
- 02.The famous discovery of penicillin in 1928 came about partly by accident: Fleming returned from a holiday to find that a mold, later identified as Penicillium rubens, had contaminated a petri dish and was visibly killing the surrounding Staphylococcus bacteria.
- 03.Fleming's discovery of penicillin did not immediately lead to its widespread clinical use; it was Howard Florey and Ernst Chain who, more than a decade later, developed methods to purify and mass-produce the antibiotic during World War Two.
- 04.In 1999, Time magazine named Fleming one of the 100 Most Important People of the 20th century, and in 2009 a Scottish Television poll voted him the third greatest Scot of all time, behind Robert Burns and William Wallace.
- 05.Fleming received honorary doctorates from multiple European universities, including the University of Madrid Complutense in 1948 and the University of Graz, reflecting the international scope of his scientific reputation.
