He called this juice "penicillin", explaining the reason as "to avoid the repetition of the rather cumbersome phrase 'Mould broth filtrate'." [12] He invented the name on 7 March 1929. [5] In his Nobel lecture he gave a further explanation, saying: I have been frequently asked why I invented the name "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 naturally-derived antibiotic.
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.
1942 – benzylpenicillin, the first penicillin; 1942 – gramicidin S, the first peptide antibiotic; 1942 – sulfadimidine; 1943 – sulfamerazine; 1944 – streptomycin, the first aminoglycoside [2] 1947 – sulfadiazine; 1948 – chlortetracycline, the first tetracycline; 1949 – chloramphenicol, the first amphenicol [2] 1949 – neomycin
Rachel Fuller Brown (November 23, 1898 – January 14, 1980) was an American chemist best known for her long-distance collaboration with microbiologist Elizabeth Lee Hazen in developing the first useful antifungal antibiotic, nystatin, while doing research for the Division of Laboratories and Research of the New York State Department of Health.
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.
How the Microwave Was Invented by Accident Pictorial Parade - Getty Images Yes, the microwave oven was invented accidentally, when a test for a magnetron melted an engineer’s snack in 1946.
Antibiotics revolutionized medicine in the 20th century. Synthetic antibiotic chemotherapy as a science and development of antibacterials began in Germany with Paul Ehrlich in the late 1880s. [8] Alexander Fleming (1881–1955) discovered modern day penicillin in 1928
