Sir alexander fleming - biography

Alexander fleming penicillin. Alexander Fleming's discovery was not known.

History of Penicillin Originally noticed by a French medical student, Ernest Duchesne, in 1896. Penicillin was re-discovered by bacteriologist Alexander Fleming working at St. Mary's Hospital in London in 1928. He observed that a plate culture of Staphylococcus had been contaminated by a blue-green mold and that colonies of bacteria adjacent to the mold were being dissolved. Curious, Alexander Fleming grew the mold in a pure culture and found that it produced a substance that killed a number of disease-causing bacteria. Naming the substance penicillin, Dr. Fleming in 1929 published the results of his investigations, noting that his discovery might have therapeutic value if it could be produced in quantity. Dorothy Crowfoot Hodgkin Hodgkin used x-rays to find the structural layouts of alexander fleming

Atoms and the overall molecular shape of over 100 molecules including penicillin. Dorothy's discovery of the molecular layout of penicillin helped lead scientists to develop other antibiotics. Dr. Howard Florey It was not until 1939 that Dr. Howard Florey, a future Nobel Laureate, and three colleagues at Oxford University began intensive research and were able to demonstrate penicillin's ability to kill infectious bacteria. As the war with Germany continued to drain industrial and government resources, the British scientists could not produce the quantities of penicillin needed for clinical trials on humans and turned to the United States for help. They were quickly referred to the Peoria Lab where scientists were already working on fermentation methods to increase the growth rate of fungal cultures. One July 9, 1941, Howard Florey and Norman Heatley, Oxford University Scientists came to the U.S. with a small but valuable package containing a small amount of penicillin to begin work.
