Alexander Fleming, The Discoverer of the Antibiotic Effects of Penicillin
Abstract
In 1928, Sir Alexander Fleming observed the bacterial-killing effects of penicillin in his laboratory in London. This was the first step in the discovery of one of the most important pillars of today’s medicine: the antibiotics. It took many years to find a way to produce penicillin in large amounts, and large-scale production did not start until 1945. However, to this day, Fleming is considered the father of the antibiotics, and without his discovery we could not treat many infections caused by bacteria. This means that, without antibiotics, even a small infected wound could become fatal. In addition, surgery is much safer with antibiotics, and people with weak immune systems (like children or elderly) can now easily recover from bacterial infections. However, bacteria are becoming resistant to antibiotics, which was also predicted by Fleming in 1945, during his acceptance speech for the Nobel Prize.

Sir Alexander Fleming knew in 1936 bacteria would beat antibiotics
Dr Bill Frankland, acclaimed allergy expert and now 106 years old, recalls clearly when Sir Alexander Fleming foretold the demise of antibiotics.
As you can hear in this interview, Dr Frankland, who worked with Fleming at Imperial College London, remembers hearing Fleming’s dire warning as a medical student in 1936.
Not long before this, in 1928, Fleming had discovered the first ever antibiotic – penicillin – at St Mary’s Hospital, London.
Fleming said there would be a revolution, but doctors will overuse it, and because bacteria have to survive...they will become resistant to itDr Bill Frankland
Dr Frankland, who was awarded an MBE for his services to allergy research, recalls: “It was [at a lecture] in 1936 that Fleming said ‘we have this new substance that I have designated penicillin, because it comes from a penicillin mould.. And when we are able to use it commercially, on humans, it will change the whole of medicine.'
“He said there would be a revolution, but doctors will overuse it, and because bacteria have to survive - they are very very clever - they will become resistant to it. I didn’t know what he was talking about at the time, it seemed all r
