Hodgkin won the 1964 Nobel Prize in Chemistry, and is the only British woman scientist to have been awarded a Nobel Prize in any of the three sciences it recognizes. In 1965 she was appointed to the Order of Merit. She was the second woman [citation needed] to receive the Order. In 1976, she was the first woman to receive the prestigious Copley ...
The first volume is dedicated to Penicillin and her research on that topic. The British Journal of Surgery published a review on the book in 1953 reading: "It is a veritable encyclopaedia for the use and abuse of penicillin. It surely must take its place in the library of every hospital as valuable work of reference, not only for the clinician ...
Later, when highly pure penicillin became available, it was found to have 2,000 Oxford units per milligram. [72] Yet in testing the impure substance, they found it effective against bacteria even at concentrations of one part per million. Penicillin was at least twenty times as active as the most powerful sulfonamide. [68]
Sample of penicillin mould presented by Alexander Fleming to Douglas Macleod in 1935. 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.
They discovered that penicillin was a powerful germ-killer that reduced the severity of infectious diseases and made procedures such as organ transplantation and open-heart surgery possible. [6] Their findings received media coverage, which helped attract funding from the United States Government to mass-produce penicillin during World War II ...
Penicillin molecules are small enough to pass through the spaces of glycoproteins in the cell wall. For this reason Gram-positive bacteria are very susceptible to penicillin (as first evidenced by the discovery of penicillin in 1928 [46]). [47] Penicillin, or any other molecule, enters Gram-negative bacteria in a different manner. The bacteria ...

Commemorative plaque marking Fleming's discovery of penicillin at St Mary's Hospital, London. The laboratory in which Fleming discovered and tested penicillin is preserved as the Alexander Fleming Laboratory Museum in St. Mary's Hospital, Paddington. The source of the fungal contaminant was established in 1966 as coming from La Touche's room ...
