The history of penicillin follows observations and discoveries of evidence of antibiotic activity of the mould Penicillium that led to the development of penicillins that became the first widely used antibiotics. Following the production of a relatively pure compound in 1942, penicillin was the first naturally-derived antibiotic.
The discovery of penicillin and the initial recognition of its therapeutic potential occurred in the United Kingdom, but, due to World War II, the United States played the major role in developing large-scale production of the drug, thus making a life-saving substance in limited supply into a widely available medicine.

According to British hematologist and biographer Gwyn Macfarlane, the discovery of penicillin was “a series of chance events of almost unbelievable improbability” ( 1 ). After just over 75 years of clinical use, it is clear that penicillin’s initial impact was immediate and profound. Its detection completely changed the process of drug ...

Feb 23, 2021 · Florey, Chain and members of the Oxford penicillin team. After three years of trial and error, they developed a successful but painfully inefficient process that produced pure penicillin. The team finally had enough penicillin to start animal trials. In 1940, eight mice were infected with deadly streptococci bacteria.
The discovery of penicillin was one of the most important scientific discoveries in the history of medicine. Ancient societies used moulds to treat infections and in the following centuries many people observed the inhibition of bacterial growth by moulds. While working at St Mary's Hospital in London in 1928, Scottish physician Alexander ...
Alexander Fleming was a Scottish physician-scientist who was recognised for discovering penicillin. The simple discovery and use of the antibiotic agent has saved millions of lives, and earned Fleming – together with Howard Florey and Ernst Chain, who devised methods for the large-scale isolation and production of penicillin – the 1945 ...
