Study Notes
Alexander Fleming: British Innovator
- Born in Scotland in 1881, Alexander Fleming moved to London at age 13 and trained as a doctor.
- Began a career in research at the University of London, focusing on illnesses and vaccines.
- Served with distinction in the Army Medical Corps during World War I before returning to research.
- Discovered penicillin in 1928 after spores of the Penicillium mould contaminated his petri dishes, inhibiting bacterial growth.
The Discovery of Penicillin
- Albert Alexander, a policeman, lost an eye due to an infected scratch from a rose bush in early 1941.
- Despite the immediate effects of penicillin on his infection, Alexander died after four days due to insufficient production of the drug.
- Howard Florey, an Australian scientist, rediscovered Fleming's work and began treatment of Alexander using penicillin.
Challenges and Breakthroughs
- Early production of penicillin faced difficulties; scientists struggled to find and replicate the mould.
- Mary Hunt discovered the mould on a melon in a grocery store, providing a sample large enough for consistent reproduction of penicillin.
- This single melon has since been the source of all penicillin produced to this day.
Recognition and Legacy
- Alexander Fleming was knighted in 1944 for his contributions to science.
- Awarded the Nobel Prize for Medicine in 1945, shared with Howard Florey and Ernst Chain.
- Fleming passed away on March 11, 1955, leaving a lasting legacy through the life-saving drug, penicillin.
