The discovery of antibiotics represented a key milestone in the history of medicine.
Brief history of antibiotic development as medicines
1928: Alexander Fleming discovered the first antibiotic, penicillin. However, it took over a decade before penicillin was introduced as a treatment for bacterial infections.
1930s: The first commercially available antibacterial was Prontosil, a sulfonamide developed by the German biochemist Gerhard Domagk.
1945: Penicillin was introduced on a large scale as a treatment for bacterial infections. This was possible through the work of Florey and Chain who managed to efficiently purify the antibiotic and scale-up production. The introduction of penicillin marked the beginning of the so-called “golden era” of antibiotics.
1940 – 1962: The golden era of antibiotics. Most of the antibiotic classes we use as medicines today were discovered and introduced to the market. Each class typically contains several antibiotics that have been dis

Sir Alexander FlemingFRS FRSE FRCS[2] (6 August 1881 – 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]
He also discovered the enzymelysozyme from his nasal discharge in 1922, and along with it a bacterium he named Micrococcus lysodeikticus, later renamed Micrococcus luteus.
Fleming was knighted for his scientifi
