[5] In his Nobel lecture he gave a further explanation, saying: I have been frequently asked why I invented the name "Penicillin".
Glass phial of British Standard penicillin. 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 ...
Penicillin was discovered in 1928 by Scottish scientist Alexander Fleming as a crude extract of P. rubens. [6] Fleming's student Cecil George Paine was the first to successfully use penicillin to treat eye infection (neonatal conjunctivitis) in 1930.
"It was an accident" is never a phrase that you want to hear in the laboratory -- well, almost never. After all, taking an experimental drug from the fume hood of a chemistry lab all the way to ...
The 1961 edition of Encyclopedia Britannica vol.9 p.371 Title: Fleming, Sir Alexander - states that his discovery of the antibacterial powers of the mold from which penicillin is derived was made in 1928 and was a "triumph of accident and shrewd observation."
Her first visit to China was in 1959. Over the next quarter century, she travelled there seven more times, the last visit a year before her death. [60] Particularly memorable was the visit in 1971 after the Chinese group themselves independently solved the structure of insulin, later than Hodgkin's team but to a higher resolution.
Production of antibiotics is a naturally occurring event, that thanks to advances in science can now be replicated and improved upon in laboratory settings. Due to the discovery of penicillin by Alexander Fleming, and the efforts of Florey and Chain in 1938, large-scale, pharmaceutical production of antibiotics has been made possible.
The true story is that it was invented utterly by accident one fateful day more than 70 years ago, when a Raytheon engineer named Percy Spencer was testing a military-grade magnetron and suddenly ...
